Skill: Make equal groups

Explanation and Free Practice Resources

Making equal groups means partitioning a collection into groups with the same whole-number quantity, determining either the number of groups or the number in each group, and relating the groups to the total. Drawings and arrays reveal that equal groups can be counted by repeated addition or skip-counting and represented by multiplication situations; sharing and grouping are inverse ways to reason about the same quantities. Fractions, unequal groups, and division with remainders are beyond this scope.

Detailed Explanation: Make equal groups

Equal groups have the same number of objects in every group.

Example: Mia has $(12)$ stickers. She puts them into $3$ equal groups. How many stickers are in each group?

Draw $3$ groups:

\boxed{\phantom{xx}}\quad \boxed{\phantom{xx}}\quad \boxed{\phantom{xx}}

Share the stickers one at a time, giving one sticker to each group during each round. After $4$ rounds, each group has $4$ stickers:

\boxed{4}\quad \boxed{4}\quad \boxed{4}

Check that the groups make the total. Add the groups:

4+4+4=12

Write the multiplication fact:

3 \times 4=12

So, there are $4$ stickers in each of the $3$ equal groups.
