Shape and area

Students identify and name circles, triangles, rectangles, and squares, describing each shape by its number of sides and corners.

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

Students identify familiar 2D shapes regardless of their size, colour, or rotation, understanding that shape is defined by attributes not appearance.

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

Students identify spheres, cubes, cylinders, and cones in real objects, describing attributes such as flat faces, curved surfaces, and edges.

K.G.A.3: Identify shapes as two-dimensional (lying in a plane, "flat") or three- dimensional ("solid").

Students sort a collection of shapes into two-dimensional (flat) and three-dimensional (solid) groups, explaining the difference between the two categories.

K.G.A.3: Identify shapes as two-dimensional (lying in a plane, "flat") or three- dimensional ("solid").

Students compare two shapes by counting sides, corners, or faces and describe how the shapes are alike and different.

Students sort a mixed set of shapes using a chosen attribute such as number of sides or type of surface, and justify their sorting rule.

Students combine two or more simple shapes to build a larger shape, such as joining two triangles to make a rectangle.

K.G.B.6: Compose simple shapes to form larger shapes.

Students use a variety of flat shapes to compose pictures, patterns, and designs, describing which shapes they used and how they fit together.
