Factors Color Board

This "Connect 5" Factors Game was developed as a challenge to make a game with the original Prime Climb Chart. We noticed that the original Prime Climb Chart was very ink-heavy, so we created a different one with different colors, sector distributions, and a white background.

The Factors Color Board can be used in a similar way to how Dan Finkel describes it in his Five Principles of Extraordinary Math Teaching TEDx Talk. Amanda Klahn has a post about how she uses the board in her classroom, and Amie Albrecht (senior lecturer and applied mathematician at the University of South Australia, Adelaide) writes in this post about using the Prime Club hundred chart with a group of 50 pre-service teachers.

Taking about the board can turn into a great math discussion! Kids should start by looking at the graphic projected on a white board. Appropriate questions are:

  • What do the circles have in common?
  • How are they different?
  • What do you notice about the colors and numbers?
  • What could it have to do with prime or composite numbers?
  • why do the numbers in the last column alway have yellow and red colors?
  • What color means "even"?
  • Does it mean anything that green spots are always going in diagonals?
  • Why are some of the spots black?

1. Rules of the Factors Game

The rules of the Connect 5 game are these, but they are included in the file:

If all numbers are already used, the player gets a point (valid for action 7). If the board is so full it does not allow a player to get 5 tokens on a line, the game ends and the player with the most lines of 4 tokens wins!

Playing this game can help kids who just started learning prime and composite numbers to get more of a background. Its purpose is to get familiar with how the numbers in the Hundreds Chart are composed of their corresponding factors.

Many children in fifth grade start learning about prime and composite numbers. This is a phenomenal game that will test children´s skills on primes and composites.
