Identify and describe shapes

Analyze, compare, create, and compose shapes.

Standard(s)

NC.K.G.2 Correctly name squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres regardless of their orientations or overall size.

NC.K.G.3 Identify squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres as two-dimensional or three dimensional

NC.K.G.4 Analyze and compare two- and three-dimensional shapes, in different sizes   and orientations, using informal language to describe their similarities, differences, attributes and other properties.

Materials

BLM of circle and square, sphere and cube 

Task

Part A:

1.      Hand the student a square.  Say:

·         What is this shape? How do you know it is a ______ (insert student’s shape)?

·         After rationale is provided, provide correct shape name if needed.

·         Is this a 2 dimensional or 3 dimensional shape?  How do you know?

2.      Hand the student a cube.  Say:

·         What is this shape? How do you know it is a ______ (insert student’s shape)?

·         After rationale is provided, provide correct shape name if needed.

·         Is this a 2 dimensional or 3 dimensional shape?  How do you know?

3.      Hand the student both the square and cube. Say:

·         How are the square and cube similar?

·         How are the shapes different?

Part B:

1.      Hand the student a circle.  Say:

·         What is this shape? How do you know it is a ______ (insert student’s shape)?

·         After rationale is provided, provide correct shape name if needed.

·         Is this a 2 dimensional or 3 dimensional shape?  How do you know?

2.      Hand the student a sphere. 

·         What is this shape? How do you know it is a ______ (insert student’s shape)?

·         After rationale is provided, provide correct shape name if needed.

·         Is this a 2 dimensional or 3 dimensional shape?  How do you know?

3.      Hand the student both shapes.  Say:

·         How are the circle and sphere similar?

·         How are the shapes different?

Continuum of Understanding

Not Yet Proficient

●       Cannot name shapes

●       Is not able to compare the shapes

●       Does not use geometric attributes to describe/justify shape names

Progressing

●        Correctly names some the shapes

●        Uses some geometric attributes to describe/justify shape names (e.g., number of sides, number of edges, number of corners, etc.)

●        Can determines if shapes are 2-D or  3-D but cannot explain their rationale
