Class Experience
Did you know that the abacus has been in use since before the adoption of written Hindu-Arabic numerals? Join this class as we learn how to perform calculations using this handy device, which has been in use for thousands of years! In this class, we will learn how to represent whole numbers (up to the hundred-thousands) and decimals using a soroban or suanpan abacus. We will then learn how to add and subtract numbers on the abacus -- including problems that require regrouping. We will also cover a brief history of different types of abacuses around the world. Session 1: How to represent numbers on a soroban or suanpan. Whole Number Addition with No Regrouping. Session 2: Subtraction with No Regrouping Session 3: Advanced Addition (with re-grouping) Session 4: Advanced Subtraction (with re-grouping)
