Complete Me (Fractions)

A fraction game to teach students how fractions can fit together to form a whole.

Learning outcomes:
  • Understanding of how fractions can fit together to make a whole
  • Understanding of the difference in size of fractions
Required Material:
  • White board
  • White board Marker

Aim of the game:
  • Fill in the whole shape by shading a specified fraction of it. The winner is person who shades the final segment and creates a whole.

How to Play:
  1. This game can either be played in pairs with each person playing against each other or as the teacher verses the class.
  2. Start by drawing a whole circle, square or shape of your choice on the white board.
  3. Select three or more fractions that each player can choose from (depending on what fractions you choose will determine how difficult the game will be, there are examples down the bottom).
  4. Each player takes in turns to choose which fraction of the whole shape to fill.
  5. The player who fills in the last piece to complete the whole is the winner, if the player has no choice but to fill in more than a whole than that player loses. (eg if there is only an eighth left but the player can only choose from a half, quarter or sixth)


I would suggest easing into this game with simple fractions first (eg half, quarter) also you might want to use fractions that fit in with each other (eg 1/3 1/6 1/2). As the students get better at understanding fractions you can give more difficult combinations. Here are some good combinations to use; (1/2, 1/4 and 1/8) (1/4, 1/8 and 3/8) (1/8, 2/8 and 3/16) (1/9, 1/3, 4/9)
(1/5, 3/10 and 7/20)you can move to higher and more dificult combinations with; (1/9, 1/3 and 1/6) (1/3, 1/4 and 1/12). Experiment with some different fraction combinations, if you get your students to play against each other and come up with their own combinations they will develop a good understanding of how fractions relate to each other and which fractions are compatible.
