My Favorite kNOw

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.

Arlene Crum
Director of K-12 Mathematics

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.

Within our classrooms, each student has strengths and cultural knowledge that support the classroom learning environment.  To ensure learning for all students, we must broaden our understanding to break down barriers, build a supportive culture and offer equitable access to opportunities for growth.
