What This Standard Means
What Students Need to Do
- Students start with a total and a given number of equal groups. They find how many objects belong in each group and show that every group has the same amount.
What Mastery Looks Like
- Students can share or sort a total into a given number of equal groups. They use a drawing, objects, repeated subtraction, or a division equation to find and explain the group size.
Common Misconceptions
- Students may confuse the number of groups with the number in each group. They may make unequal groups, lose track while sharing, or ignore leftover objects.
How to Assess It
- Exit ticket: “Share 24 stickers equally among 6 students. Draw a model and write how many stickers each student receives.”

Ways to Teach It
Give pairs 30 counters and task cards naming different numbers of groups, then have them share the counters equally and record each result.
Ask, “How are 18 objects in 3 groups different from groups of 3?” Students draw and explain both situations.
Play a card game where students draw total and group cards, build equal groups with cubes, and earn points for correct group sizes.
Plan equal snack bags by dividing 24 crackers among 4, 6, or 8 students and comparing how many crackers each receives.
