Math K-7 IRP Shape and Space (3-D Objects and 2-D Shapes)

Students describe the characteristics of three-dimensional (3-D) objects and two-dimensional (2-D) shapes and analyse the relationships among them.

Prescribed Learning Outcomes Illustrated Examples
It is expected that students will:
  • explore and describe real-world and three-dimensional objects using descriptive attributes such as big, little,like a box, and like a can
    		• -> Reach into a bag filled with different objects and see if you can find the can or cylinder. How did you know you had found the can or cylinder? Reach in and hold another object. Describe your object.
  • explore, identify, and classify three-dimensional objects in the environment according to their properties
    		• -> Sort and classify a selection of objects (e.g., cans, cones, balls, glasses). Explain your classification. Experiment to discover which objects will roll.
  • construct three-dimensional objects using materials such as plasticine, blocks, and boxes
    		• -> Choose a 3-D object. What is your object called? Make a model of it, using modelling clay, play dough, or blocks.
  • identify and describe specific two-dimensional shapes such as circles, squares, triangles, or rectangles
    		• -> Sort this collection of geodot shapes into two groups. Name each group.



    Find another way to sort the drawings. Identify each shape as a circle, triangle, rectangle, or other.
  • construct and rearrange a design using a set of two-dimensional shapes
    		• -> Here is a design made of squares. Does it match the clap, slap pattern? Use more squares to continue the pattern to the edge of the desk. What is another way to describe the design?

  • compare, sort, classify, and pattern two-dimensional shapes
    		• -> Take a scoop full of blocks:
    • sort out the red ones
    • push the blocks back together, then sort out the blocks that are triangles
    • make up your own sorting rule, then sort the blocks by your rule
    • make a pattern using the blocks
