"Mathematics instruction typically involves a correct answer. But what if, instead of penalizing students’ mathematical mistakes, we use their errors as vehicles for deeper mathematical understanding? In Celebrating Mathematical Mistakes: How to Use Students’ Thinking to Unlock Understanding, Nicole M. Wessman-Enzinger and Natasha E. Gerstenschlager posit that students’ mathematical errors can be ripe teaching opportunities that allow for more meaningful learning. In this practical guide, Wessman-Enzinger and Gerstenschlager define three types of mathematical mistakes and offer several strategies and task structures-including play and games-that encourage creative and flexible mathematical reasoning. Part of the Growing the Mathematician in Every Student collection, Celebrating Mathematical Mistakes moves beyond the correct-incorrect paradigm by acknowledging the beauty, power, and ubiquity of mathematical errors"--
