A fun and unique way to help students memorize their math facts! Students wrap the string from the problem on the left to the answer on the right, then turn the Wrap-Up® over to see if the answer is correct. Use a stopwatch to measure improvement and to see how fast they can go. Each set contains 10 self-correcting boards and covers all the facts for that operation. Includes one set each of addition, subtraction, multiplication, and division.
