**Activity #1**

**Understanding Division.**

Many students have trouble with division; in the most part because the concept isn’t well understood. Some might have been absent from school on the critical day it was explained. In the simplest term, Division is counting how many times you can subtract a number (**divisor**) from another number (**dividend**) until the remainder is smaller than the number that is subtracting. The number of times you can subtract is called the **quotient**, and what is left over, is called the **remainder**.
