Skill: Form groups of a given size

Explanation and Free Practice Resources

A collection is partitioned into groups containing the same specified number of objects, so the learner connects the total quantity with repeated groups of equal size and can determine how many complete groups are formed. The learner distinguishes equal groups from unequal partitions and can identify a small number of objects left over when the total does not divide evenly; formal multiplication or division procedures, larger numbers, and generalized remainder rules are not included.

Detailed Explanation: Form groups of a given size

To make equal groups, put the same number of objects in each group.

Example: Make groups of 33 from 1010 counters.

  1. Start with 1010 counters.
  2. Put 33 counters in the first group.
  3. Put 33 counters in the second group.
  4. Put 33 counters in the third group.
  5. Count what is left: 11 counter.

You made:

3331 left\boxed{3}\quad \boxed{3}\quad \boxed{3}\quad \boxed{1\text{ left}}

There are 3 complete groups of 3, with 1 counter left over. Each complete group has the same size.
