Open strategy sharing allows you to nurture the norms needed for a productive math talk community. In open strategy sharing, students listen for and contribute different ways to solve the same problem. The teacher asks questions that invite children to share their thinking. Students are then oriented to tracking and repeating their classmates strategies to show understanding.
Teachers use this strategy when they want to draw out different methods of thinking or different strategy use. Teachers use this task to honor the principle that children are sense makers. Teachers plan for open sharing by selecting a problem that students would be able to solve in a number of different ways.
Use the Open Strategy Sharing template to think through the following instructional plan:
Teachers pick a problem that can be solved in more than one way.
Teachers anticipate what students may do to solve the problem.
Teachers take anectodal records while students share their thinking, gathering 2 - 4 different ways
Teachers can use Talk Moves and clear representations to help students understand what they hear.
Close by highlighting the different ways students thought about the problem.
Provides a strong foundation for mathematics discussions.
Helps teachers build wide parti
This strategy comes from chapter 3 of the book Intentional Talk: How to Structure and Lead Productive Mathematical Discussions by Elam Kazemi & Allison Hintz
