Traffic Lights App

Great way to give your child an understanding of place value!

How to Play

The Traffic Lights game is a great way to give your child an understanding of place value at the same time as helping them to develop logical thinking.

The app chooses a secret number and the player has only six guesses to find it. The Traffic Light clues show that the guess has:

  • GREEN: The right digit in the right place of the secret number
  • ORANGE: The right digit, but in the wrong place of the secret number
  • RED: The wrong digit and so not anywhere in the secret number

There are three levels, using 4-digit, 5-digit and 6-digit secret numbers. Just as you feel safe at one level, it’s time to go on to the next.

A Rationale for using the app

When we first devised the Traffic Lights game, we played it with a High School class at Kulkarriya Community school, situated on the banks of the Fitzroy River deep in the heart of Western Australia. We were looking for a way to make the spoken use of large numbers have a purpose and found that, after initial difficulties had been cleared up, the students were fluent in their ability to write down and say a 4-digit number as they guessed what the secret number might be.

Once we had fixed the rules, the game soon became a favourite with the class and was often used as a quick warm-up to a maths lesson.

In the classroom

The Traffic Lights program supports the Year 3 and Year 4 statements for number recognition in the Australian Curriculum: Mathematics. In the lesson plan given below, you will see how the app can be used for a Mental Routine and as a Game to develop number sense.
