Polar Bear Activities, Polar Bear Polar Bear,

We did pretty watercolor pictures with winter animal cutouts added…..Link HERE to the tutorial.

At DLTKs website they did a lot of other things with  Polar Bear, Polar Bear.  And they also have the puppets that you can copy in black and white or color to use to make your own big book, puppets or minibooks for your students.  I love their website  HERE.

Everydayteaching.com had this cute polar bear art project.


I also do some fun activities with Polar Bear, Polar Bear also by Bill Martin, in the wintertime.Eskimos and characters from Stone Fox by John Reynolds Gardiner, which I like to read in the wintertime, and all the arctic animals are our characters in an ARCTIC ADVENTURE STORY.

 Another link for Polar Bear activities is HERE at dltk teach.

Here at filefolder fun is a cute arctic animal matching game that would be great for a center during this unit. Some free polar bear writing paper can be found at Classroom Freebies.

Marco the Polar Bear Poem
Marco the Polar Bear white as the snow,
Sat down on the ice near the cold water’s flow.
“Lunch! I need lunch,” he said “I’ll make a wish!”
He stuck in his paw, and up it came with a fish!

Polar Bear Facts:  Link HERE to Kidsoup
  • The polar bear is the world’s largest land predator.
  • They can be found in the Arctic, the U.S. ( Alaska), Canada, Russia, Denmark (Greenland), and Norway.
  • Females usually only have two cubs and they have these babies in a cave that they’ve dug in a large snowdrift. The babies are about the size of a rat and weigh only a pound.
  • Male polar bears may grow up to 10 feet tall and weigh can over 1400 pounds. Females can grow to 7 feet and weigh up to 650 pounds. 
  • In the wild polar bears live up to age 25.
  • A polar bear’s fur is not white. Each hair is clear hollow tube. Polar bears look white because each hollow hair reflects the light. On sunny days, the polar bear’s hair traps the sun’s heat to keep the bear warm.
  • Polar bear fur is oily and water repellent. The hairs don’t mat when wet, allowing the polar bears to easily shake off water and ice.
  • Polar bears have wide front paws with webbed toes that help them swim. They paddle with their front feet and steer with their hind feet. Their paw pads are rough, helping to them from slipping on the ice.
  • Polar bears have been known to swim 100 miles at a stretch.
  • Polar bears primarily eat seals.
  • A male polar bear is called a boar and a female polar bear is called a sow.

HERE at Jan Brett’s website  are lots of pretty blacklines of all of her winter characters that you can use  to do activities with polar bears as the theme.

  I love Bill Martin Books! And I love doing Polar Bears as a theme in winter.

Valentines Day Card Holders

Valentines Day Card Holders 

These are the Valentine Holders we do every year to collect Valentine cards in. Super cute right?

And we line them along our bulletin board in the hallway so it is easy to walk along and drop the cards in. I also have them write about what  they LOVE ABOUT THEMSELVES. It’s a hard assignment for most kids. But an important one. 

 Start by taking a rectangle piece of butcher paper from the rolls. Then fold up the bottom to make the heart pointed bottom.

Then staple the Valentine Holder together, just the top pieces at the seams. I usually staple twice on each one. 

 Next, cut 2 rounded edges along the top of each one. I do all of these steps for the kids or I get a mom helper to do it a week before Valentines day.

This is one of my centers on Valentines Day….filling the hearts of your friends. So sweet! 

  I usually choose the colors of red, pink, purple (2 shades) and white. The kids get to choose which color they like. We make 1 for the principal and 1 for the teacher to. That’s me. LOL.

 Then we decorate them with stickers, die cut punch outs, copied heart designs on colored paper etc. The kids get to choose whatever they like. Some years I buy small doilies too in heart shapes. 
Finished heart valentine holders 

 Another game we do is HOT POTATO HEART, using a small stuffed heart to pass around. When you are out you get to choose a treat from a bag of treats.

    Here everybody is being silly for the camera, playing hot potato. Then as part of this center we also make a heart bead bracelet using pipe cleaners and pony beads. I usually have bought some special heart beads of some sort too.

Hi MOM! Happy Valentines Day! 

 This year I found little metal penguins and hearts and star beads to add to our bracelets. Kids just did their own bracelets

I had to show you my cute decorations at home that I put up.
I love Valentines Day Decor! So sweet. 
And we decorate the classroom pretty good for Valentines Day too! 

 The 3rd center is decorating a Valentine cookie with frosting and candy. Here are some finished cookies we made this year.

Valentine Cookie decorating 
We had a mom helper at every center…thanks everybody! Here we are decorating cookies….

A pretty finished Valentine cookie. 

All the kids loved decorating their cookies. They were huge so I told them only eat half before lunch. 

 Bulletin board with “I LOVE MYSELF BECAUSE” writings and our finished Valentine Card Holders.

Valentines Day Card Holders and “I Love Myself” writing….

 The 4th center for Valentines Day centers is Valentines Bingo using conversation hearts as markers.

The heart bowl has cool prizes for winners. Everybody gets a candy prize though, thanks to
the parent helpers who each brought a bag of candy. Yum! 
The Valentines Party sure was a fun day for everybody. Hope yours was too!

100s Day Fun

Thursday was the 100th Day of school. We HAD to celebrate!

Our 100s day badges we wore all day.

And our 100s Day hats of course…..Patties Classroom kids 2013 on 100s day. 
And we drew pictures of what we will all look when we turn 100 years old…haha….I don’t look forward to THAT I don’t think, from the looks of it….lol…

Look what I have to look forward to!  Lots of grey hair and canes and stuff.

And some kind of red problem area that will happen to my hands! EEK!

One of the assignments was to bring in a brown bag of 100 edible things and write 3 clues on the bag for us to guess what was inside. Then we put all the stuff in a big bowl, mixed it up and passed out cups of 100s Day Trail Mix!
Then I passed everybody a 100 dollar bill (fake of course) and asked them what they’d spend it on if it were real? 

Here’s what they all came up with. Some of them would give to the poor. Loved that.

And many of them would buy toys for little brothers and flowers for their mom. Sniff…..

And some of them would buy a Disney Cruise vacation! Let’s GO! I wish 100 dollars went as far as they think it will go….snicker….

Poem we read with 100 words.

We read as a class a short chapter book called 100 Days at the Black Lagoon School. It was hilarious. I had a whole class set. We also read the Fancy Nancy book above and the Scholastic 100th Day of School.
I put 100s day stickers on everybody’s writing too.

It’s a lot of fun to mark the 100th day of school each year.  I love doing all the fun activities.

We had a lot of fun on 100s Day!

A Froggy Fable and Frog Life Cycles

Reading Streets A Froggy Fable inspired our Frog Facts Reports and Oil Pastel Frogs 

Our Reading Streets Literature book had the cute story A Froggy Fable by John Lechner last week. We decided since we had already written fables a month ago that we would write non fiction frog fact reports instead. They turned out really nice.

 My kids LOVED watching this Youtube to introduce kids to Frog Life Cycles.

 I am trying to teach thematically with the new Reading Streets Literature Series we adopted this year.It is my favorite way to teach. So we spent a few days going through the writing process. We wrote sloppy copies, had a teacher edit, rewrote and then did an illustration of a tree frog.

 I have the kids do a frog life cycle, a beautiful art project Frog, using Crayola oil pastels, and we write an Frog Fact report too. We compare and contrast Frogs and Toads and read lots of interesting books and some old Scholastic News magazines I’ve saved on Frogs and Amphibians.

 We had tadpole and amphibian as two of our vocabulary words this week, as well as all the amazing words in our Reading Streets literature book.

Our frog fact books and cute, green, construction paper Frogs from last year were cute too. Here was our finished bulletin board. This would also be a fun art project to link up with Reading Streets A Froggy Fable.

Here are our finished FROG FACT BOOKS we filled with interesting Amphibian facts.  Did you know that frogs only have a row of upper teeth, and they have forked tongues? Yeah, me neither!! 

Frog Puppets we made one year on sticks. 

I sometimes do a cute Frog and Toad activity using the story “The Lost Button” story taken from the Frog and Toad are Friends book. It is using buttons and problem solving skills to decide which button shape Frog has lost. Check it out HERE.  And we take some time comparing frogs and toads and their differences. A great Frog versus Toad comparison I showed the kids is HERE at the Virtual Vine. I also have a Weekdy Reader that compares them in pictures.  A good Anchor chart idea and graphic organizer comparing frogs and toads isShe has a free graphic organizer frog versus toad printable that I copied off for the kids to fill out.

Fun Froggy counters for math  and a big floor puzzle would be fun to this little unit. I love to teach this way having all my centers match the topic I am teaching; in this case FROGS! 

We looked at lots of pictures of tree frogs from the rain forest and saw them in all colors of the rainbow. That’s probably why there is a blue frog here; we saw one in the Weekly Reader we read! HERE at Scholastic is a great frog life cycle printable.

We used 1/2 inch wide and foot long strips of red paper rolled around our pencils and glue under the mouth for the froggy tongues. They add a little 3D to the art.

I collected rocks last summer from Bear Lake to do this activitys . But when we made ours, some of the kids did ladybugs and others did rainbows. Next year I’ll add the wiggly eyes and the green legs underneath….cool idea from Brimful Curiosities.

Some printables including a life cycle you can copy can be found HERE at treeonline. . This is definitely a red eyed tree frog!! 

5 Green and Speckled Frogs is a song we sing and use finger puppets along with. The kids LOVE singing to it  HERE at dltk Kids.  I have the book above and we just turn pages as we sing the familiar tune. I made the frogs with 2 layers of green felt, some yellow felt for the mouth, dark green for the eyes and wiggly eyes and glue gunned them together. I left a slit open underneath for fingers and then polka dotted them with Sharpie marker. They are fun to bring out once a year when we sing the song.

Here is my copy of the songbook and 5 little felt finger puppet frogs I made from green and yellow felt and glue gunned wiggly eyes on them. I leave them at the science center with all of my books on frogs.

Five Little Speckled Frogs (song lyrics)
Sat on a speckled log
Eating the most delicious bugs. Yum! Yum!
One jumped into the pool
Where it was nice and cool
Now there are Four green speckled frogs 

Four Little Speckled Frogs
Sat on a speckled log
Eating the most delicious bugs. Yum! Yum!
One jumped into the pool
Where it was nice and cool
Now there are Three green speckled frogs (keep going down to none)

 Another thing I like to do during all my science units is to make a “graphic organizer” shaped like the animal we are studying; in this case, a frog!

Here’s an old one I had tucked away…..no quote marks on this one, but sometimes I’ll write out the facts the kids find and put quotation marks and  then “said Tommy. It helps the kids learn how to do quotation marks.

 Graphic organizers shaped like the item you are studying is a great way to keep your facts and information up during a unit so it can be referred to often. Kids learn a lot better this way….with lots graphics and repeating of information.

Frog Jokes JUST FOR FUN! 

Q: What happens if a frog parks in a bus stop?
A:  He gets toad away!

Q:  Why are frogs always happy?
A:  Because they eat whatever bugs them.

Q:  What happens when two frogs catch the same fly?
A:  They get tongue-tied!

Q:  What do you get when you cross a pig with a frog?
A:  A ham-phibian!

Q:  What kind of frog lives in a tree house?
A:  A tree frog!

These jokes would look so cute written on these little bulletin board pieces, wouldn’t they? I’ve got to get a set of these!!! And a few more froggy  jokes! 
Frog Facts Report writing…..
I also have these Frogs on a Log addition and subtraction center that is fun. It is great for practicing skip counting by 2s and 3s as well as subtraction on a number line in the younger grades. I have the logs
 all from 1 to 10. You could also just make “logs” with 1 to 10 marked on  brown construction paper hand drawn “cylinders”  and use frog counters below. They come in neon colors the kids would love!  
A poem we sang to “Jimmy Crack Corn” tune…

Lyons 25 Note (G-G) Bell Set with Case  

We sing this song to classroom instruments like Xylophones Here at Musician’s Friend as well as using some percussion instruments from my musical instrument drawer. Check it out in my music instrument store at page top.

My students LOVE playing this in pairs and it is only $20.00!! It doesn’t matter what notes they play to the beat, it always sounds pretty. Check out my store page above and you can order one. I use the 3 I bought at least once a week when we sing piggy back songs to core information poems.

 Posters and Scholastic News we read about Frog Life Cycles and we compare and contrast Frogs and Toads.

 Cool posters add a lot when left throughout the unit. We actually hung this one out in the hallway when we were through with our reports and bulletin board and lots of kids loiter reading the captions under the pictures.

Beautiful Non Fiction AND  Literature I have collected to read to students or use for facts in our reports.

The bulletin board looks as colorful as real tree frogs of the rain forest. Ribbit….

Groundhogs Predict Weather


This February 2nd is Groundhog’s Day.  For fun we are going to be doing some Groundhog Activities for the day. I thought of writing comic strips or puppet shows. But for a fun activity after math I passed out some Groundhog Gameboards. I told them to design their own Candy Land-Type game for Groundhogs Day using 10 Math Facts in Multiplication, 5 cards, 4 positive and 4 negative situations to land on.

       Here’s a cute VIDEO and SONG about Groundhogs Day that my students will LOVE!

They made up their own Groundhogs Day Games!
They needed to use their groundhogs  in colors to match their Groundhogs Day Gameboards….
With cards telling  Groundhog consequences….super cute! 

We started making Groundhog Gameboards using math multiplication facts.  We copied some ideas from Candy Land (using bridges and colored groundhog cards to move to different locations on the board) but overall we made up our own fun boards and wrote out fun things as they land on colors and pick a Groundhog color card. Here were some of the CARD consequences they came up with today…. PICK A GROUNDHOG CARD GAME….1. Fell into a snake hole, miss a turn.2. Snowy avalance ahead, hop forward 3 spaces.3. Chased by a bobcat, run ahead 2 spaces.4. Go over the Groundhog Bridge.5. Fell into Shadow Swamp, skip your turn.6. You saw your shadow, stay in your den for 1 turn.

We had poems and songs on the back of our Groundhogs Day games that we read and sang too…..
And they all put 10 multiplication math facts into their games….

A CUTE art project and prediction chart I found at this Mrs. Williamson’s Blog.

We made a prediction on weather the groundhog will see his shadow or not. There were 12 votes YES he will and 9 votes no he will not.  We’ll see the results tomorrow in the news! 

A cute PATTERN for a Groundhog Art project is HERE at Finally in First.

Groundhog Day ART- This would also make a cute HAT with just a brown strip and the hands just to the left
and right of the head like he’s peeking out of his hole. I LOVE the teeth! 
These were the first few that got finished with their Groundhogs Gameboards…..we haven’t played them yet….
They will be excited to play each other’s games on Groundhog Day, February 2nd! 

They added math facts on their boards. It was fun seeing the kids color their boards and add matching groundhog colored cards with questions of all kinds on them. These kids are very creative!

We got these blacklines out of the January Teacher Helper Magazine….

 HERE at ARTIST HELPER is a website where you can get a printable gameboard and some little groundhogs to copy off if you want to make your own.  I got mine out of the monthly teacher helper magazine for January.

Groundhogs for consequence cards or multiplication math facts…. Everybody got 10
Isn’t this the CUTEST cupcake you ever saw? Groundhog Cupcakes would be a sweet treat today! 
I showed the kids an old Candyland gameboard…to get some cool ideas….

Another site that has lots of Groundhogs Day Activities is HERE at Artist Helping Teachers.

Then we brainstormed some fun things we could write up on cards or spaces on the Gameboards

We Sang this Groundhog Song to the “I’m a Little Teapot” Tune….

          Geoffrey Groundhog Predicts The Weather (Turtleback School & Library Binding Edition)             

We read a few stories about Groundhogs too. And we read some funny poems about groundhogs and sang  songs. We also had a vote on if the groundhog will see its shadow tomorrow or not. I’m hoping we don’t have 6 more weeks of WINTER! Brrrr…… We will  watch the youtube of Punxatawny Phil to find out. HAPPY GROUNDHOGS DAY 2013! 

I found this Darling video about Groundhogs. Did you know they were Woodchucks? They are so cute!  

Penguin Tear Art and Stories by 2nd Graders

 Every year in January when it is super snowy cold outside, we get out the penguin books and magazines and we decide to write a story copying the style of Helen Lester in one of my most beloved children’s books: Tacky the Penguin.

Our Bulletin board of penguin stories and tear art penguins. 
Tacky the Penguin is my favorite children’s story book of all time.

My very favorite children’s book is called Tacky the Penguin by Helen Lester. She is a wonderful children’s author. The story is all about a comical, odd bird who does not conform and doesn’t fit in. (hmmm…maybe I feel a kinship to this bird, ya think?)  I love books like this because of course, by the end of the story, all those who didn’t really like Tacky, grow to love him when he saves the day. The author has written a slug of similar books starring Tacky, and he cracks me up in every single one. It teaches kids a lesson too: that just because somebody is different doesn’t mean they don’t have a lot to offer. (yeah, all of us oddballs have something in common….).

 Trenton the Scientist Penguin gets himself into a lot of trouble!

And who wouldn’t love an opera singing penguin from Bangalore? Hmmm?

Love the cute “microphone” she is singing with….too funny! 
I think this artist penguin has an art easle here with an abstract of falling snow…..sweet! 

 So we start by reading and laughing at Tacky and all his antics in several books. Tacky does odd things because he is an “odd” bird.” (It repeats this phrase throughout the story). We brainstorm other types of penguins like scientist penguins, doctor penguins and football star penguins, and I ask what kinds of things each would like to do? 

 I take all their crazy ideas and we do a brainstorm on the board. For example, a rock star penguin might like to play guitar on stage and sing in a microphone. A football player penguin might like to tackle other penguins and throw football spirals, or make touchdowns in an icy stadium full of screaming penguin fans. This takes time and energy. But I may have a future Mark Twain or Hemingway in my group, who knows? 

The artist penguin looks so cute like he’s a little frenchie complete with a beanie and a painter’s pallette.

Weekly Readers and Science Spin Magazines I have Saved over the years and the kids read these in small groups to get more of a background on Penguins of the Antarctic. I always read them the book Mr. Popper’s Penguins during this time too. It is a chapter book my teacher read to me one year. I still remember how much I loved it! 
A Graphic Organizer for listing penguin facts one year when we did a Penguin Fact Book. 

 I always ask them to add 2 describing words to their stories after they are done. Word choice is an important feature. We like $100 words like “fantastic” and “awesome” and “humungus” a lot better than $1 words like “good” and “nice”And our word wall is papered with $100 words the kids have come up with. So you don’t have to reinvent the wheel every writing. A cute art project using a toilet paper roll can be found HERE

Gotta love a Super Hero Penguin, don’t ya? 

 For the penguins we tore little, 1 cm strips of white paper into a pile of “snowflakes bits”. Then we used a  9 x 9 inch square of bright blue construction paper and glued the little snowflake bits on the bottom of the page forming a small “hill” for penguins to stand on (or snowboard on….LOL ). 

Football Player Penguin…so cute.

Here is a fun webcam to watch the penguins in their habitat HERE.

Got to have a penguin from Las Vegas, now don’t ya?

We had several “Rock Stars” in the group too! 

 We then drew a black “potato” shape on black construction paper and tore around it. This was the body. Glue that on the hill. Then we tore a black round head and tore 2 “finger shaped” flippers. I punched out white holes from a hole puncher and went around each desk and dropped 2 holes for eyes. They glued those on their heads and used a sharpie fine point marker to make tiny black dots on the eyes. Then they tore 2 small, orange feet and  cut out a yellow triangle beak. 

Cute soccer ball and soccer penguin. 

Snowmen and Penguin math and literacy pages can be printed and some challenge added. I’ll  use the Snowmen sentences to have the kids write their vocabulary definitions and the snowmen syllables for their spelling words practice.This would be a fun center if I laminate them on cardstock to reuse them different weeks during the winter.

Last Year we did Penguin Acrostic Poems to go with our art project. It was cute too. Here are a few.

 Penguin Acrostic Poems.

 Then we did Footprint Penguins. They took a LOT of time. The kids kept squealing that the paint was cold! lol. The small penguins are thumbprints. These turned out cute too. But the kids enjoy making their own tear art penguins much better I decided.

Here are some of the books I read to the kids
about Penguins. 

This is a cute Snowman Syllables literacy page from Live Love Laugh’s Cute K  website.

Hope you enjoyed the penguin stories and art. We sure  had some good penguin fun writing them and being artsy, designing them, I’ll have to say.

Layers of the Earth Clay Models

We finished our study of rocks and minerals and the rock cycle. We made crystals, painted pet rocks, made flap books on the 3 types of rocks and we read many books too. 

Just for fun I showed them the 4 layers of our earth in a coloring page model and then we made clay models using a metal BB for the inner core, and 3 colors of clay for the other 3 layers. It was lots of fun. Everybody chose different colors of clay. Then we pushed a popsicle stick into them and cut out a little wedge to see the layers.

Here we have the CRUST, THE MANTLE, THE OUTER CORE AND THE INNER METAL BB CORE. I bought regular modeling clay with a coupon at Hobby Lobby.

What are the four main layers of the Earth? Check out this worksheet HERE. We had fun making a clay model on a popsicle stick.

  • THE INNER CORE – It is the fourth and innermost layer of the Earth. Here, temperatures reach 7,000 degrees Fahrenheit. The inner core is also made up of molten iron and is 1,500 miles thick. It will be represented by a metal BB. 

My little student Svetha did a beautiful colored model and labeled the 4 layers of the earth Here. 
• THE OUTER CORE – It is the third inner layer of the Earth. The outer core is made up of molten iron and is 1,425 miles thick. It will be represented by red clay wrapped around a BB.

We had a wordsearch with questions on the back of the coloring page model of the Earth’s Layers.

• THE MANTLE – It is the second layer of the Earth. It is the thickest layer, at 1,750 miles thick. Many minerals in the mantle are hot enough to become liquefied yet. It will be represented by orange or yellow clay. 

 THE CRUST – It is the outermost layer of the Earth and is between four to 25 miles thick. It is made up of sand, dirt and rock. It will be represented by blue clay. 

Everybody colored their coloring page of the Earth’s layers  to match their clay model.  

A cool lesson plan and free worksheet on  layers of the earth can be found HERE at Volcanoes Alive.
Another one I liked is at aktsunami.com. It had a downloadable fill in the blank diagram that looked fun and both of these will go along with my clay lesson plan. Another great resource for Rocks is HERE at mjksc teaching ideas. One of their worksheets I might try with my students is HERE.

I liked this one a lot. I think next year I’ll try to find just green blue and red clay. 

We learned about the Rock Cycle – mostly from this THINKQUEST and a few books and posters on Rocks, Volcanos, Crystals. I have posters like these in my classroom, plus we watched the Magic School Bus video on Volcanoes.  Thanks to one of my mom helpers and Andrew, her son, we had a cool demonstration of a Volcano erupting using baking soda and vinegar and a model volcano.

Here is my class with their clay models of the earth’s layers. I think they liked doing them.
ROCK FAMILY SONG Check out this song about the different types of rocks HERE.

A fun wordsearch and a little quiz on layers of the earth to go with it can be downloaded Share PDF.net. It is a little tricky to figure out how to download it, just follow the directions (type in the code) on the upper left hand side of the page. If you go anywhere else it is all advertising tricks. Another one she had was giving each student a mini snickers bar unwrapped in a baggie. They press and sit and stand on the snickers bar and it becomes “changed” like a metamorphic rock, with heat and pressure. What a great idea!

HERE  is a cute printable SONG about the 3 types of ROCKS!
Check out ROCKY’s Rock Cycle. Also HERE  at Have Fun Teaching is a Rocks ABC Order Worksheet we also did. It has many of the vocabulary words we studied this week.This KIDS GEO.COM website is SUPER GREAT  because it has  cute songs to go along with  WONDERFUL pictures of all 3 rock types.

I got this cute book Lets Go Rock Collecting  on Amazon. It was just right for teaching the Rock Cycle to 2nd Graders. I have the Gail Gibbons book Planet Earth/Inside Out on order. It looks good too!

VOCABULARY WORDS THIS WEEK – all from our unit. We also used them for spelling words. 

1. Igneous rock- rock formed from cooled magma or lava.
2. Sedimentary rock- rock that formed when sediments were pressed and cemented together.
3. Metamorphic rock- rock that formed when another kind of rock was squeezed and heated deep inside Earth’s crust.
4. Rock cycle- the process of rocks changing into other kinds of rock.
5. Fossils- the remains or traces of an organism that lived long ago.
6. Volcano- a mountain built up from hardened lava, rocks, and ash that erupted out of Earth.
7. Lava-melted rock that flows out of the ground onto Earth’s surface.
8. Magma- melted rock below Earths surface

9. erosion – when bits of rock and sand are taken away by wind or water and packed as sediment somewhere else. 
10. crystals – a mineral having a clear structure with cut faces. (like quartz) 

Check out the other things we did for Rocks HERE and for Crystal Experiments and HERE. I think we 
did pretty good for a first try at this unit. The gal who used to teach it retired last year and we forgot to ask her to leave her stuff, so I had to invent the unit from scratch this year. I think it turned out great!
