Reason with shapes and their attributes
(Standards 3.G.1-2).
Standard 3.G.1
Understand that shapes in different categories (for example, rhombuses, rectangles, and others) may share attributes (for example, having four sides), and that the shared attributes can define a larger category (for example, quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
-
An Introduction To Quadrilaterals
In this lesson the student is introduced to parallelograms, rectangles, and trapezoids and practices creating various types of quadrilaterals.
-
Floor Tiles
This lesson will help students identify and examine symmetry in geometric figures
as well as describe and classify polygons.

Geometry (3.G) - Third Grade Core Guide
The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Third Grade Mathematics - Geometry (3.G)

Grade 3 Unit 4: Geometry (Georgia Standards)
In this unit students will further develop understandings of geometric figures by focusing on identification and descriptions of plane figures based on geometric properties. Identifies examples and non-examples of plane figures based on geometric properties. Identify differences among quadrilaterals. Understand that shapes in different categories may share attributes and those attributes can define a larger category (example: rhombuses, rectangles, and others have four sides and are all called quadrilaterals). Expand the ability to see geometry in the real world and can draw plane figure shapes based on attributes.

Perimeter
This lesson plan and activities will help students understand the concept of perimeter.
-
Sets and the Venn Diagram
This lesson is designed to help students understand the ideas surrounding sets and Venn diagrams.
-
Sets and The Venn Diagram (Beginner)
By introducing students to the idea of a set, this lesson will help students learn about the vocabulary of sets and Venn diagrams, as well as how to arrange things in a Venn diagram.
-
Venn Diagram Shape Sorter
This lesson is designed to introduce young students to the concept Venn diagrams and explore different kinds.
