Unlike other audios, the "Wrap-up Rap" uses a random order to practice the facts. They also go through each set of problems three times; once with the answers given, one without, and if a student can keep up with the faster pace of the third time, they have probably learned their facts. Use independently or with Learning Wrap-pups. Choose from Addition, Subtraction, Multiplication, and Division. Use them once and you'll understand why teachers consider these to be the best audio CDs for teaching math on the market.
