CGI is a philosophy of teaching mathematics based on the teacher's knowledge about how children solve story problems. Problem solving is a focus of instruction, with children deciding how they should solve each problem. Many problem solving strategies are used to solve problems.
Children communicate to their teaches and peers how they solved the problems.
Teachers understand children's problem-solving strategies and use that knowledge to plan their instruction. Children have knowledge of mathematics, which should be used as a basis for instructional decisions 2. Children develop mathematical understanding and acquire skills by solving a variety of problems in any way that they choose 3. Children gain understanding and inform other children and their teachers as they communicate their mathematical thinking. At Wilson School the Six Trait Writing model is used in first grade through fifth.
