Geometry 1.G 1 . 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. 2. 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.5 3. 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 <span style="font-family: 'Gotham-Book','serif'; font-size: 12px;">. Describe the whole as two of, or four of //<span style="font-family: 'Gotham-Book','serif'; font-size: 12px;"> the shares. Understand for these examples that decomposing into more equal shares creates smaller shares
