Lesson 1. Unit 4. Grade 6 Open Up Resources
This Instructional Activity is a part of the Lesson 1, Unit 4, Grade 6. This lesson aims to give students a concrete setting for thinking about division. Students estimate how many of each given object are needed to make a stack of a given height. To do so, they use what they know about the sizes of familiar objects (boxes, bricks, notebooks, and coins) and their intuition that it takes more of a thinner object and fewer of a thicker object to reach the same height.
