# How Many Squares?

- You will need grid paper and rulers for this activity.
- Have your kids draw a rectangle on the grid paper and draw a straight line diagonally from corner to corner.
- Have them find how many squares the line passed through.
- Instruct them to draw several other rectangles of differing sizes and find the number of squares that a diagonal line passes through for each.
- They should be able to come up with a system that will work with any size rectangle.
