K.G.2
2. Correctly name shapes regardless of their orientations or overall size.


1.K.2
2. Compose twodimensional shapes (rectangles, squares, trapezoids, triangles, halfcircles, and quartercircles) 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.G.2
2. Partition a rectangle into rows and columns of samesize 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.


4.G.2
2. Classify twodimensional 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. (Twodimensional
shapes should include special triangles, e.g., equilateral, isosceles, scalene, and special quadrilaterals, e.g., rhombus,
square, rectangle, parallelogram, trapezoid.) CA


5.G.2
2. Represent realworld 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.
