Description
Exercise Name: Axis of symmetry
Math Missions: 4th grade (U.S.) Math Mission
Types of Problems: 3

The Axis of symmetry exercise falls under the 4th grade (U.S.) Math Mission. This exercise introduces the idea of an axis of reflectional symmetry.

Types of Problems[]

There are three types of problems in this exercise:

  1. Make the line of symmetry: This problem asks the user to make a line going through given dots that will be an axis of symmetry of a given shape.
    Aosmakeline

    Make the line of symmertry

  2. Make the symmetric shape: This problem asks the user to create a shape that is symmetric with respect to a given line.
    Aosmakeshape

    Make the symmetric shape

  3. Choose the axis of symmetry: This problem draws a shape and give several potential reflectional symmetry lines. The user is expected to selects all of the lines that are axes of symmetry.
    Aosmultselect

    Choose the axis of symmetry

Strategies[]

This exercise is hard to get accuracy badges because some of the pictures can be a little subtle. It is hard difficulty to attain speed badges because of the time needed to move things around to make shapes.

  1. When the symmetry is close, it is a good idea to use a piece of paper or other "ruler" to make sure you are selecting correct answers or drawing correct shapes.
