Math3-5
Understanding Division Models for 4th Grade
By Kirsten L.
A mini lesson and practice set that introduces partitive, measurement, and comparison division through relatable contexts like sharing cookies and cutting ribbon. Students build fluency in identifying which division story a problem tells and in explaining their reasoning, making it well suited to a 45-minute math block or small-group work.

Teacher Guide & Tips
- Open with the cookie and ribbon examples in the key terms section as a whole-class mini lesson, asking students to act out sharing versus measuring with counters or paper strips before naming each model.
- Discussion question: How do you know whether a problem is asking how many in each group or how many groups? Ask students to point to the clue words in the problem.
- Scaffold for struggling readers: provide a three-column chart labeled Total, Group Size, Number of Groups, and have students fill in the known and unknown before solving.
- Extension for advanced students: have them write their own partitive and measurement word problems for the same number pair and explain how the story changes the division.
- Plan roughly 10 minutes for the mini lesson and 25 to 30 minutes for practice, with a brief share-out at the end.
