K.G.B.5

Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.


 

 

Summary:

Giving students opportunities to build, use computer graphic programs, and draw will allow them to deepen their understanding of the properties of two-and three-dimensional shapes.

Understanding the Standard:

  • Students need opportunities to create drawings, stencils, and cutouts to represent two- and three-dimensional shapes. 
  • Students need opportunities to build three-dimensional shapes from blocks, straws, clay, and other objects.
  • Students should pick out shapes they see around them - hexagonal stop sign, square cake, circular pie, etc.
  • Students can use simple tools like stencils, tracing paper, blocks, playdough, and sticks to create two- and three- dimensional objects.
  • Building shapes and drawing shapes can help teachers check whether students know the attributes of a shape.

Specific Questions to Focus Instruction:

  • Given the appropriate materials, can students make a desired shape?
  • Can students discern the materials needed to construct a specific shape?
  • Are students able to point out where the corners are on their shape?
  • Can a student make a bigger version of the same shape if asked?
  • Does the student use the defining attributes of a shape as starting points for making it? For example, to  make a square, does he draw four points first? Or perhaps use the corner of the paper to make a right angle?

Skills

Prior to: Students recognize shapes that look familiar.

At Grade Level:
By building and drawing shapes, students continue to understand and tend to think about the attibutes of shapes.

Moving Beyond: Students will make two-dimensional or three-dimensional shapes with the appropriate materials. Additionally, they can compose these shapes with specific attributes that are unique to each one. They use the models they create to discover new facts about shapes, such as how they can be composed or decomposed to form other shapes (a square can be divided into two right triangles).
