Kindergarten Mathematics Geometry: 2D Shapes

Understandings:

  • Students must be able to identify two-dimensional shapes, including circles, triangles, and rectangles. They must be able to see that a square is a special rectangle. Students should be able to identify two-dimensional shapes by the number of vertices and edges the shapes may have. Students should realize that the identity of the shape is not changed by its orientation, size, color, or texture. (K.6) A
  • Students should be able to identify attributes or characteristics of two-dimensional shapes using informal language such as corners and sides and transfer those terms to more formal language such as vertices and edges. (K.6) D
  • Students must be able to classify and sort two-dimensional and three-dimensional figures based on attributes of the shapes and figures such as vertices, edges, etc. and realize that the identity of the shape is not changed by its orientation, size, color, or texture. (K.6) E
  • Students will draw or make two-dimensional shapes such as circles, triangles, squares, and rectangles from materials such as toothpicks, straws, string, clay, chenille sticks, etc. as well as through the use of technology. Students should remember that orientation, size, color, and texture are not attributes that identify a two-dimensional figure. Vocabulary students should use to create circles, triangles, squares, and rectangles include sides, edges, corners, and vertices . (K.6) F
TEKS:
  • K.6(E)(R) Classify and sort a variety of regular and irregular two-dimensional and three-dimensional figures regardless of orientation or size. (Quarter 1 regular, two-dimensional shapes only)
  • K.6(A)(S) Identify two-dimensional shapes, including circles, triangles, rectangles, and squares as special rectangles.
  • K.6(D)(S) Identify attributes of two-dimensional shapes using informal and formal geometric language interchangeable.
  • K.6(F)(S) Create two-dimensional shapes using a variety of materials and drawings
Learning Targets:
  • I can identify and create 2D shapes (K.6A, K.6F)
  • I can identify attributes of 2D shapes (K.6D)
  • I can classify and sort 2D shapes (K.6E)
Essential Questions:
  • What are the attributes of two-dimensional shapes?
  • How can shapes be named and described?

Vocabulary:  attribute, circle, curved/straight, rectangle, shape/figure, side, square as a special rectangle, triangle, two-dimensional, vertex/vertices
