Learn to Add and Subtract on the Abacus

Part 3: The Borrow and Carry Movements

This is the final section of the course where students learn to add and subtract on the abacus. Having completed Part 2: The Pull-5 and Break-5 Movements, kids can start learning the carry and borrow movements on the abacus. By the end of this section students should be comfortable adding and subtracting any three-digit numbers on the abacus and have the skills to tackle larger numbers. This course is great preparation for the Custom Abacus Math Tool where kids can fine-tune their skills with large numbers.
