Reflection and Symmetry• If you draw an imaginary line down the

center of whatever you're looking at, both sides would be a mirror image of each other. This would also show symmetry

Try these activities on symmetry Math: Symmetry

Reflection• You can FLIP a shape and show it’s

reflection. Make a shape. Highlight the shape. Click ‘Draw’. Choose FLIP. Your shape will FLIP and you will see its reflection.

Sorting Shapes• My sorting rule is:

• Shapes with curves and shapes without curves.

CURVES NO CURVES

If you want to get some shapes to work with, click here Basic Shape Patterns

Patterns• This is a 2-D Pattern:

What would be next?

• This is a 3-D Pattern

What would be next?

Make your own pattern block shape ON LINE! Pattern Blocks: Exploring Fractions with Shapes

Parallel LinesThe lines of the skis are parallel

The lines of the oars are not

The legs of the tables are parallel

The sides of the hanger are not

The edges of the paper are parallel

The edges of the paper airplane are not

Right Angles• Right angles are square corners

This is a right angle

No matter which way you look at it, it is still a right angle

This is a right angle This is a right angle

This is a right angle

Parallelogram• A parallelogram has parallel sides

Try some Tangrams! http://www.tangrams.ca/

Prisms• A prism can be named by its base

A prism with a triangular base would be called a triangular prism

A prism with a square base would be called a square prism

A prism with a rectangular base would be called a rectangular prism

Polygons• A closed figure with 3 or more line

segments is a polygon

These are polygons

These are not polygons

Can you name these shapes? Test yourself! Click here

Faces and Surfaces• Some 3-D shapes have flat surfaces called

FACES

• Some 3-D shapes have curved surfaces called SURFACES

Nets• Nets are 2-D plans with which to make 3-D

shapes. Here is a net that will make a cube.

If you cut it out and fold it up, you will have a cube

Try some nets! Nets
