Math

Strong math for grades 3–8

Visual, hands-on math apps for fractions, geometry, ratios, functions, proof, discrete math, and number sense. Built on the Concrete-Representational-Abstract pedagogy + research-backed manipulatives. Each app pairs a named cast of characters who embody curricular concepts (e.g., Halver embodies partitioning; Pie embodies wholes-and-parts) — the cast IS the curriculum.

Kids who like puzzles, building, or "show me why" will love this section.
