Our core math program is the Houghton Mifflin Series. In addition, Cognitively Guided Instruction (CGI) problem solving is incorporated throughout our math instruction.
CGI is an educational philosophy that capitalizes on over 20 years of research showing that students come to school with rich informal systems of mathematical knowledge and problem-solving strategies that serve as a basis for learning mathematics. CGI differs from rote instruction in that it puts the focus on students' mathematical thinking.
Teachers learning to use CGI strategies experience intensive professional learning about how to engage students in mathematical dialogue. As a result of CGI, students are empowered to explain their reasoning, justify their solution strategies, and thus build a deeper collective mathematical understanding. All teachers at Weaver are trained in at least 3 years of CGI strategies and receive on-going coaching throughout the year.
