Learning Perimeter

Last week students began learning about perimeter.  Although they entered 3rd grade with a lot of knowledge about perimeter, I had to help them separate their knowledge of perimeter from their knowledge of area.  They wanted to add for both, when I wanted them to multiply for area and add for perimeter.  In the end, I won the battle and they are multiplying monsters!!

For perimeter, students helped the ants of Hollow Log, design their parade route around a lake.  In addition, they designed a few more lakes so, to give the ants some options for the parade route.  Using geometric designs, a 24" long string, and triangular grid paper, students went to work helping the ants.

Students will complete their newly designed lakes this week, so stay tuned for more pictures!
