How Much Money in the Bowl?

This lesson write-up is for any 5th or 6th (or 7th) grade teacher who wants students to explore decimal concepts and refine decimal operations while exploring a compelling task that is engaging and accessible to all learners. Using an image from Andrew Stadel’s Estimation 180 page, students estimate, investigate, and then calculate the value of a bowl full of coins and demonstrate learning for 5.NBT.2, 5.NBT.7, and 6.NS.3. The write-up contains a lesson pathway with specific questions and instructional moves to consider, analysis of the opportunities for student learning, and other wisdoms and insights we learned from teaching this lesson as a part of a lesson inquiry.
