But Why Does It Work?: Mathematical Argument in the Elementary Classroom
by Deborah Schifter, Susan Jo Russell, Virginia Bastable, Traci Higgins, Reva Kasman
Enhance elementary math instruction with strategies for mathematical argument. Students identify connections in problems and equations, express observations, explore claims via manipulatives and diagrams, demonstrate validity through representations, and extend thinking across operations for deeper comprehension.
About This Book
This book focuses on developing mathematical argument skills in elementary students by emphasizing the identification of connections among problems, equations, or expressions.
It guides educators in helping learners express statements about these observed connections, encouraging clear articulation of mathematical ideas.
Through exploring claims using manipulatives, diagrams, or story contexts, students engage deeply with concepts in an interactive way.
The approach includes demonstrating the validity of claims using various representations to build confidence and understanding.
Finally, it supports expanding thinking across different operations, promoting a broader application of mathematical reasoning in the classroom.
