Domain: Geometry Cluster: Reason with shapes and their attributes.

Common Core Standard: 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.

Essential Vocabulary Task Analysis Learning Activities/Assessments Resources Prior triangle, quadrilateral, pentagon, hexagon, trapezoid, half/quarter circle, circle, cube, cone, cylinder, sphere, polygon Explicit attributes, properties, quadrilateral, open figure, closed figure, three-sided, 2- dimensional, 3- dimensional,

rhombi, rectangles, and squares are subcategories of

 Describe the properties of the geometric figures, including 2-and 3- dimensional figures.

 Sort geometric figures and state their given rule (attributes).

quadrilaterals.  Identify that some

quadrilaterals are not squares, rectangles, or

-Students will create a picture of a playground. Use all of the following shapes: circle, square, rectangle, rhombus, triangle, pentagon, and hexagon. Each shape must represent a similar piece of playground equipment. (Collaborative Group Work) (Writing to Learn) (Scaffolding) (Questions)

-Students will work in

collaborative groups to sort 2D shape cards into two groups according to their geometric attributes. They will label each group. (Collaborative Group Work) (Questioning) (Writing to Learn) (Scaffolding)

Third Grade Math

Domain: Geometry Cluster: Reason with shapes and their attributes.

Common Core Standard: 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.

 Review partitioning circles and rectangles into 2, 3, or 4 equal shares.

 Explain that partitioning is dividing a whole into equal parts.

 Partition shapes into equal groups when given the shapes.

 State that these parts all have the same area.  Identify and write the

fractional name of each part.
