The CIMM program, while still under construction, is transforming mathematics education to include conceptual understanding (grouping structure), symbol construction (algorithmic manipulations), problem solving and mathematical reasoning. The end result is that all of the notoriously difficult topics (fractions, negative numbers, place value, exponents, etc.) become trivial. Our solution is simple, as it bridges the gap between the concrete mathematics of elementary school and the abstract symbolism of high school.
