Detective Practice in Centers

Massachusetts Department of Elementary and Secondary Education 45 min(s)

This lesson is a synthesis of Lessons 1-6, in which students will model and solve change unknown, addend unknown, and difference unknown problem situations with objects, pictures, and equations. They will continue to apply discourse and justify their thinking. As you plan, consider the variability of learners in your class and make adaptations as necessary.
