In this 5-10 minute routine, students answer a question and analyze incorrect answers. The teacher quickly assesses how many students grasp the concept and what causes misunderstanding. Students engage in Mathematical Practice 3: critiquing the reasoning of others.

Welcome to K-12 Math!

Today’s mathematics calls for more than memorization of facts and formulas.  Students need to be able to analyze and interpret, reason and model, and to use a variety of problem solving strategies.  Our learning standards offer a connected structure to build fluency through conceptual understanding and to develop mathematical reasoning.  All of this occurs within a growth mindset that builds on the belief that all students are able to achieve in mathematics.
