This grade 3 quadrilaterals worksheet gives 24 problems on quadrilaterals and partitioning shapes, ordered from easy to hard, with a separate answer key.
These 24 problems practice sorting quadrilaterals and partitioning shapes. Work on rhombuses, rectangles and squares first, then move to cutting shapes into parts with equal areas and naming each part as a unit fraction. The set follows Common Core 3.G.A.1 and 3.G.A.2. The last six problems are word problems.
