After years of "reviewing" area and perimeter with my Algebra 1 students, I realized that many of my algebra students still had misconceptions about area and perimeter:
- "Perimeter is the outside; area is the inside!"
- Area is length times width (always, any shape)!
- "For area, multiply all the numbers; for perimeter, add all the numbers!"
.. and so on.
I wrote this worksheet so my struggling students could get a better grasp of what area and perimeter were really about. Higher-level students benefitted from the challenge of finding as many possible shapes as they could that fit the given constraints; lower-level students stuck to basic shapes, but at the end of the day, they had a much better idea of how to handle area vs. perimeter.
I include a reference page at the end, which is used in later activities, but introducing it to the students at this point in time helps to show them that there are many different formulas for area for different shapes.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
