Grade 3 Math Lessons
Grade 3 introduces multiplication and division as connected operations. Fractions, area, perimeter, scaled graphs, and shape classification give students several ways to reason about equal groups and equal parts.
Subjects for Grade 3
Geometry
Classify quadrilaterals and polygons by their attributes, connect area with multiplication, compare perimeter, and partition shapes into equal fractional regions.
