The Mosaic Menders — Area as Counting Unit Squares (Grade 3)

A free interactive Grade 3 math activity: help Tessa find the mosaic that uses the same number of unit tiles. One look-alike has a bigger shape but the wrong count, so children must measure area by counting unit squares — not by which looks biggest. Area is a count of unit squares, the same no matter the shape. Common Core 3.MD.C.6.

Sprout's Patchwork Meadow — Measure Area by Covering with Unit Squares (Grade 3)

A free interactive Grade 3 math activity: help Sprout the gardener carpet irregular flower beds completely with moss-patch unit squares — no gaps, no overlaps — and the area is the count of squares it takes to cover the space. The beds are L-shapes and staircases, so there is no length to multiply by a width: children measure area the real way, by covering the space with unit squares and counting them. Cover from empty, fix a covering with a gap and an overlap, predict an area, finish a partial bed, and build a bed of an exact size. Common Core 3.MD.C.6 (also 3.MD.C.5).
