Back to my geometry classes....the students have moved from triangles to polygons and I read The Greedy Triangle by Marilyn Burns to seven classes.
We started with 10 different polygon shapes cut out of construction paper (I have them with my die-cut machine in the workroom). Each student got a shape and had to glue it to a piece of computer paper, then create a drawing incorporating the polygon into the drawing. We got a LOT of houses and stop signs (even though some had hexagons and heptagons instead of octagons), but some students were very creative with their vision (see pictures below).
After reading the story we discussed what the book was trying to teach besides shapes and most of the students responded with answers like: friendship, being yourself, don't be greedy, love the way you are, etc.

I then reminded the students that math was not my favorite subject and I always wanted to know WHY we needed to learn things like polygons. I found two video clips that showed how polygons are used in the "real world." (Note to self...ALWAYS bookmark the video you find, when you find it! I only used one, because I couldn't find the other one!)
I explained to the students that one of the videos showed how polygons are used to create the three-dimensional gaming worlds they compete in at home. When you take the coloring away, you see polygon on top of polygon building the blocks of the virtual world. It's very cool (but I can't find it!)
The second video clip showed how polygons are used to build recording studios and help with the perfect sound quality of a song. I had no idea polygons could be used that way! I accessed this video from our PowerVideo database.* I like being able to make those connections for the students when I can!
