Verbally describe why a shape belongs to a given category. 2. Compose two-dimensional shapes and three dimensional shapes to create a composite shape, and compose new shapes from the composite shape, building understanding of the part:whole relationships. 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. Describe the whole as two of, or four of the shares. a. Understand for these examples that decomposing into more equal shares creates smaller shares. b. Identify examples and non-examples of halves and fourths.
