Description:

This Java applet displays one way of counting the smaller grid squares nested inside a larger grid square, such as a checkerboard or chessboard. The applet allows the user to select the size of the smaller grid square and drag it to other positions, tracking the upper left corner of each new square. The explanation reveals the formula for total number of grid squares within a N x N grid square: the sum of the first N squares.
