Cognitively Guided Instruction (CGI)
Our core math program is the Houghton Mifflin Series. In addition, Cognitively Guided Instruction (CGI) problem solving is incorporated as our Signature Practice. CGI is an educational philosophy applied to the content area of mathematics. CGI is based on 20 years of research and centers on mathematical problem solving. The focus is on children’s thinking, and students are asked to explain their reasoning process, share their explanations with the class, and justify their strategies. Teachers learning to use the CGI method are given intensive professional development. All teachers at Tustin Memorial are trained in CGI.
