 Cognitively Guided Instruction (CGI) and Extending Children's Mathematics (ECM) 
Teachers Development Group is a national center for the development and implementation of CGI and ECM professional development, which are designed to enhance teachers’ ability to teach math for understanding by increasing teachers’ understanding of children’s mathematical thinking. Linda Levi, co-author of the CGI books for teachers and member of the CGI research and development team, directs this work.  CGI's content focus is Operations & Algebraic Thinking and Number & Operations in Base Ten as described in the K-3 Common Core State Standards for Mathematics (CCSSM).  ECM's content focus is Operations & Algebraic Thinking, Number & Operations in Base Ten, Number & Operations – Fractions, the Number System, and Expressions and Equations as described in the grades 3-6 CCSSM.  Through a focus on children’s thinking, teachers in CGI and ECM professional development improve their ability to engage students in the Standards for Mathematical Practice described in CCSSM. Both CGI and ECM develop teachers’ ability to use any curriculum to teach math for understanding. For more information about CGI or ECM professional development, please email Linda Levi,
