Description

Start your journey on a far-away planet mining for the mineral Corodium. Corodium is an important energy source used by multiple alien races! In order to harness the energy of Corodium, you will explore and learn the concept of symmetry!

Instructions

Play through this interactive game to learn about Identify Lines Of Symmetry. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Given a half of a shape draw the other half to create a symmetric figure.

Identify and draw lines of symmetry in quadrilaterals.

Squares have 4 lines of symmetry (Half both vertical and horizontal as well as diagonals in both directions), Rectangles have 2 lines of symmetry (Horizontal and vertical), trapezoid has 1 (vertical), parallelogram has 0 lines of symmetry.

Recognize and draw line(s) of symmetry and line-symmetric figures. (May be multiple or no lines of symmetry given the shape).

Discussion Questions

Before the Game

What does it mean if a shape is described as symmetrical? What does it mean if a shape has a mirror image? What is the line or axis of symmetry? What shapes have a line of symmetry?

After the Game

How many lines of symmetry does a square have? How many lines of symmetry does a trapezoid have? Why is the line of symmetry also called a mirror line? When might it be important to be aware of the symmetrical properties of a shape? How does a star represent a rotational symmetry of five? How could you tell that the irregular shapes had no lines of symmetry? In which shape(s) did the number of lines of symmetry equal the number of sides?
