Cognitively Guided Instruction (CGI)

Cognitively Guided Instruction (CGI) is an approach to teaching mathematics that emphasizes understanding how students think about math concepts. Instead of just demonstrating procedures, teachers observe students’ reasoning, helping them build on their existing ideas. CGI encourages students to explore, reason, and explain their thinking, fostering deeper understanding. It focuses on recognizing diverse problem-solving strategies and guiding students to develop mathematical confidence and flexibility. Overall, CGI supports meaningful learning by valuing students' mathematical ideas and promoting an active, interpretive approach to math education.
