Cognitively Guided Instruction (CGI) 
Teachers Development Group is a national center for the development and implementation of CGI professional development, which is 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 at grades K-2 is Operations & Algebraic Thinkingand Number & Operations in Base Ten as described in the K-3 Common Core State Standards for Mathematics (CCSSM). CGI’s content focus at grades 3-6 is Operations & Algebraic Thinking, Number & Operations in Base TenNumber & 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 professional development improve their ability to engage students in the Standards for Mathematical Practice described in CCSSM. Both CGI K-2 and CGI 3-6 develop teachers’ ability to use any curriculum to teach math for understanding. For more information about CGI  professional development, please email Linda Levi,, or  download a flier.
