Resize a rectangle to hit a target area or fence length — and watch how one can change while the other stays put.
The child resizes a rectangle on a grid to hit a target area or a target fence length, watching one measure change while the other can stay the same. Feeling that same area can have different perimeters deepens measurement sense. Best for Grades 4–5.
