About Us

Math Snacks are games and animations that convey math in creative, visual, and applied ways. Players explore imaginative worlds where they build skill with ratios, number groups, expressions, place value, order of operations, and graphing relationships. Mathematics educators, mathematicians, learning specialists and game developers collaborated to develop and test materials and conduct integrated research activities, professional development of teachers, and investigation into impact on learners. Accompanying teacher and learner tools support an inquiry-based approach grounded in theory-based pedagogy and the construction, not just transmission, of knowledge.

Math Snacks is a multidisciplinary project of New Mexico State University, originally brought together by Dr. Karin Wiburg, and later led by Dr. Karen Trujillo, both with NMSU’s College of Health, Education, and Social Transformation. Math Snacks materials were developed with support from the National Science Foundation (0918794). Some materials were originally prototyped or discussed as part of a cooperative agreement from the U.S. Department of Education (U295A050004).
