3rd Grade Geometry

This page provides samples of 3rd Grade Geometry Activities aligned with the Common Core State Standards. All activities are suitable for use in Math Centers, small group or whole class settings and are designed to  provide opportunities for students to communicate their reasoning and mathematical thinking. All sample files are in PDF format. Sample activities listed in blue are available for immediate download. Activities listed in **grey are available in our 3rd Grade Math Centers eBook.

Reason with shapes and their attributes
3.G.1 Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g. quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Sample Activities:
Shape Match
Quadrilateral Riddle
Also included in 3rd Grade Math Centers
** Geoboard Squares
** Comparing Quadrilaterals
** Classify Shapes Using a Venn Diagram

3.G.2 Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
