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.

2. Partition a rectangle into rows and columns of same-size squares and count to nd the total number of them.

3.G.2
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.

2. Classify two-dimensional gures based on the presence or absence of parallel or perpendicular lines, or the presence or
absence of angles of a speci ed size. Recognize right triangles as a category, and identify right triangles. (Two-dimensional
shapes should include special triangles, e.g., equilateral, isosceles, scalene, and special quadrilaterals, e.g., rhombus,
square, rectangle, parallelogram, trapezoid.) CA

2. Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and
interpret coordinate values of points in the context of the situation.
