This is a 20 slide PowerPoint file. (.pptx)
There are 10 slides with 1 question each followed by 10 slides with the answers.
No copies to make! Students can just number a paper from 1-10 to record answers as they work on a computer with a partner. You can remove the answer slides & collect their work, or leave them in and have students self-correct.
This addresses 3rd grade standard:
Common Core 3.MD.8
Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters.
I see this as one of many review stations that students would visit in a comprehensive test prep frenzy. (hopefully your district doesn't go nuts like mine does!) It could also be viewed as a whole class with a projector.
