Addition Table Puzzle app for iPhone and iPad

In this App, 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.

These setting determine the size of the Table Puzzle that the student will try to solve. For example, if 2 x 2 (the simplest) is chosen there will be two numbers along the left side of the square and two along the top of the square, with four empty boxes to be filled with correct answers. If 5 x 5 (the most challenging) is chosen, there will be five numbers along the left side and the top and there will be 25 empty boxes to be filled.
