In a Sharing Task that elicits a modeling strategy of building up, students consider how many snacks each person will eat and then build up using repeated addition or multiplication or a visual model illustrating these ideas.
The resources in this section will help you implement Building Up Sharing tasks in your school or classroom. Each example will provide planning slides, student handouts, viewing guides for video, and annotated student work. *Click here for Planning Resources and register for the password to view videos.
