This document provides divisibility rules for determining if a number is divisible by 2, 5, or 10. It explains that a number is divisible by 2 if the ones digit is even, divisible by 5 if the ones digit is 0 or 5, and divisible by 10 if the ones digit is 0. Examples are given to illustrate these rules and students are given practice problems to apply the rules.

3. Vanessa conducted a game called “The
Boat is Sinking.” She asked her 20 guest
kids to group themselves by 2’s and no
one was eliminated.
Why is that so?

4. “Divisible by” means when you divide
one number by another the result is a
whole number.

5. Divisibility rules help you determine if a
number is divisible by 2, 5 and 10. This
can help us to identify the common
factors of a number.
