Mathematics is the final core element of a STEAM school, emphasizing the logic and reasoning of in-depth mathematical study. At Heritage Elementary, we are utilizing the instructional philosophy, Cognitively Guided Instruction. Cognitively Guided Instruction (CGI) encourages ingenuity, communication, and reasoning in mathematics.
CGI is a philosophy and method of teaching math that allows students to deeply explore a math problem through problem solving and differentiated number sets. The method aligns with the developmental stages of math learning, beginning with students building number sense and one-to-one correspondence, growing to the eventual use of algorithms. Students build reasoning through writing and sharing their mathematical thinking, justifying their response.
