I use Scavenger Hunts to review a lot of different subjects in my classes. In this one, students are given either the volumes or surface areas of two similar polygons. Using this information, they are to find the scale factor. (ratio of similarity)
I have another Scavenger Hunt where students given the scale factor and use it to set up a proportion to find the correct value of 'x'. That one is: Using the Scale Factor of Similar Polygons Scavenger Hunt
Students have fun with Scavenger Hunts. They try hard to find the correct answer so their team can finish first!
It includes instructions of how to use the Scavenger Hunt, a worksheet that students can use to record their answers, and a homework worksheet that reviews the same subject.
