### Description

12 lesson plans are directly aligned with ALL Common Core Standards for 1st Grade Geometry.

Content includes:
-distinguishing between defining and non-defining attributes
-building and drawing shapes to possess defining attributes
-composing two-dimensional and three-dimensional shapes to create a composite shape
-compose new shapes from a composite shape
-partition circles and rectangles into two and four equal shares

Students will explore these concepts in the following ways:
-through picture books with corresponding activities
-using 2D and 3D shape manipulatives
-using Geoboards and rubber bands
-playing Shape BINGO
-building shapes with popsicle sticks and Play Dough
-creating 2D shape artwork
-playing "What Shape Am I?"
-completing shape puzzle boards
-creating original shape puzzles
-playing several review games on the computer
-building composite shapes with manipulatives and other objects
-using food, Legos, and pattern blocks for equal shares
-completing a Fraction Quilt to display
-creating a partitioning shape display
-using circle cut-outs, index cards, and yarn to partition shapes
-completing the following worksheets: Shape Attributes Chart, Shape Attribute Worksheet, What Shape Am I? Worksheet, Shape Seek Worksheet, and Equal Share Worksheet (answer keys included)

Students will review the concepts through a performance based review and then be assessed using the Geometry Performance Assessment. Both include checklists and break down each standard individually.

### Standards

to see state-specific standards (only available in the US).
Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
