2-D and 3-D Shapes

We have recently been learning about 2-dimensional and 3-dimensional shapes (solids) in Math.

Students are expected to:
  • identify and describe common two-dimensional shapes (e.g. squares, triangles, circles, ovals, rectangles, etc.) and sort and classify them by their attributes (e.g. colour, size, number of sides)
  • identify and describe common three-dimensional figures (e.g. cubes, cones, cylinders, spheres, rectangular prisms) and classify them by their attributes (e.g. colour, size, texture, number and shape of faces)
  • describe similarities and differences between an everyday object and a three-dimensional figure (e.g. a can of pop looks like a cylinder, a dice is a cube, etc.)

Here are some activities that you might like to try at home.

Tangrams

Students use tangrams to complete the puzzle.

Solids Matching Game

Students play a memory game to make pairs of solids.

Shape Identification

A shape is highlighted in the image and the student needs to identify which solid it is.

Shapes At Home

Walk through your home with your child. Together, find circles, squares, rectangles, and triangles. Here are some examples of shapes you might find:

Circle

rectangle

square




When you find a shape in your home, have your child do the following things:
1. Trace around the outside of the shape with a finger.
2. Describe the shape.
3. Draw a picture of the shape.

Encourage your child to bring his or her shape pictures to school to share with the class.

Have fun exploring shapes together.
