Addition Table Puzzle

A square appears with numbers along the left side and along the top

In this program, a square appears with numbers along the left side and along the top. Each of the numbers on the left side becomes one number in an addition problem and each of the numbers on the top becomes the second number. On the bottom of the screen are several numbers which are the answers to the addition problems. The student should click and drag the correct answer to the addition problem made by the numbers on the left of and above one of the empty squares in the puzzle. The student drops the correct answer into this empty square and continues clicking and dragging and dropping until all the squares are filled.
