Essential Skills and Knowledge	Teacher Resources	Student Resources
3.G.A.1  Reason with shapes and their attributes.
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. "I Can" Statements: I can identify and define two-dimensional shapes based on their attributes. I can identify rhombuses, rectangles, and squares as quadrilaterals. I can define attributes. I can describe, analyze, and compare properties of two-dimensional shapes. I can compare and classify shapes by attributes, sides, and angles. I can group shapes with shared attributes. I can draw examples that are and are not quadrilaterals.

3.G.A.2  Reason with shapes and their attributes.
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. "I Can" Statements: I can divide shapes into equal parts. I can describe the area of each part as a fractional part of a whole. I can divide a shape into parts with equal areas and describe the area of each part as a unit fraction of a whole.
