A partnership between SIAM and COMAP, Guidelines for Assessment and Instruction in Mathematical Modeling Education (GAIMME) enables the modeling process to be understood as part of STEM studies and research, and taught as a basic tool for problem solving and logical thinking. GAIMME helps define core competencies to include in student experiences, and provides direction to enhance math modeling education at all levels.

Written and reviewed by a mix of professionals to present various levels and perspectives, GAIMME includes example problems and solutions, levels of sophistication, discussion of teacher implementation, and suggestions for assessment.

The second edition includes changes primarily to the Early and Middle Grades (K–8) chapter.
