My daughter is mastering her multiplication tables, and since the workbooks that you can buy are so insanely expensive, I created the Random Multiplication Creator. it creates a worksheet of 100 random multiplication problems. Give it a base number (say 2), and a maximum number (say 9), and it will give 100 problem of 0-9 times 2. Quite handy for getting the tables memorized. Print them out! time your kids! they should get around 50 problems dome per minute (or more!)
