3rd Grade Quadrilaterals and Partitioning Shapes Worksheet (PDF)
This quadrilaterals practice worksheet for 3rd Grade covers quadrilaterals and partitioning shapes (Common Core 3.G.A.1, 3.G.A.2), with a free PDF to print.
These 24 problems practice 3.G.A.1 and 3.G.A.2. First sort quadrilaterals by attributes such as equal sides, right angles, and parallel sides. Then cut shapes into parts with equal area and name each part with a unit fraction.
The problems go from easy to harder, and the last six use stories and several steps. Draw, count, and explain.
