In this lesson, students will understand the meaning of the unknown as the size of the group in division.
In this lesson, students interpret the unknown in division using the array model.
In this lesson, students model division as the unknown factor in multiplication using arrays and tape diagrams.
In this lesson, students interpret the quotient as the number of groups or the number of objects in each group using units of 2.
In this lesson, students interpret the quotient as the number of groups or the number of objects in each group using units of 3.
In this lesson, students learn how to apply the distributive property to decompose units for division.
This short video and interactive assessment activity is designed to teach third graders about grouping with illustrations - word problems.
This short video and interactive assessment activity is designed to teach fourth graders about division terms.
Markers in Boxes Remix is a remixed version of the original Illustrative Mathematics activity. I've added an an extension activity for early finishers or those with more advanced skills.
Markers in Boxes Remix is a second generation remix where students need an additional skill of representing and solving problems.

This is the About the Cluster document written by the NC2ML group who created the instructional frameworks. This is a great resource to read while starting to plan for Gr 3 Cluster 1.
This resource is from Tools 4 NC Teachers. This document is the About the Cluster document created by the authors of the NC2ML Instructional Frameworks. This document should be read prior to teaching this cluster. This document is not remixable since the document has been written by creators of the NC2ML Instructional Frameworks.

In this Cyberchase activity, students begin by using manipulatives to share objects among different sized groups. After watching a video clip that demonstrates dealing out rounds (or sets) of objects to solve a problem, the students work on a few division problems on their own. A second video clip demonstrates how to solve such problems using numbers. With the handout, students learn to write these problems as multiplication and division facts.
This is from Tools 4 NC Teachers. It is intended to be used during Clusters 1 or 4 of Grade 3.
