How Many Squares?

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