# Introduction

The Math Leadership Corps (MLC) believes that all students are capable of becoming mathematical thinkers, critical problem solvers, and self-regulated learners who embrace a positive mathematical identity. We also believe that the quality of mathematics teaching has the greatest impact on students’ learning.

# The MLC model

MLC partners with a school district over three years to engage teachers and administrators in learning and executing a Professional Learning System & Math Instruction System.

#### A K-12 Professional Learning System

MLC works with teachers and administrators to collaborate around best math education and leadership practices to design a coherent Math Professional Learning System that supports teacher’s math instruction and prioritizes students that are proficient in mathematics.

#### A K-12 Math Instruction System

The Grade K-5 system is based on Cognitively Guided Instruction (CGI). CGI emphasizes students engaging in rigorous problem solving and communicating their mathematical thinking and problem solving strategies, resulting in the development of deep conceptual understanding.

The Grade 6-12 system is based on Math Learning by Design (MLD). MLD builds on CGI by emphasizing mathematical thinking and applying an engineering design process to create a learning experience that is active, connected, reflective, and embraces problem solving.

MLC trains and supports all K-12 math teachers on these instruction systems so that teachers can develop all students’ mathematical thinking, problem solving, and self-regulation to build mathematical identity.

#### K-12 Student Mathematical Identity

MLC’s Professional Learning System and Math Instruction System provide a foundation for teaching students mathematical thinking, problem solving and self-regulation, at all grade levels.

#### Outcome of MLC

- An internally accountable Professional Learning System that supports implementing and continuously improving a Math Instruction System.
- A Math Instruction System that builds ALL students’ mathematical thinking, problem solving, and self-regulation skills.
- Mathematical thinkers, problem solvers, and self-regulated learners who embrace a positive mathematical identity.
