We will explore number theory topics found in the Common Core State Standards and discuss ways to support student engagement in proof and reasoning. Participants will create proofs for operations with numbers by using manipulatives such as Unifix cubes and base-ten blocks. I will share implications for mathematics teacher educators and teachers.
