Perimeter

Today we learned about perimeter.  Now, in third grade, the students did learn perimeter.  But it was simple, add all sides together.  In fourth grade the students will have to apply that knowledge.  Not only solve, but compare the perimeter of 2 figures.  Find the total of 2 or more figures' perimeter.  They may be given the total and asked to find the missing side.  Or, given the total and find the missing data of 2 sides.  Here is a poster we made in class today to help us remember.
