Title – ‘Complete Me’ Fractions Game
By – David Brown
Primary Subject – Math
Grade Level – 3-7
- Understanding of how fractions can fit together to make a whole
- Understanding of the difference in size of fractions
- 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:
- This game can either be played in pairs with each person playing against each other or as the teacher verses the class.
- Start by drawing a whole circle, square or shape of your choice on the white board.
- Select three or more fractions that each player can choose from (which fractions you choose will determine how difficult the game will be)
- Each player takes turns choosing which fraction of the whole shape to fill.
- 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, then that player loses (such as when there is only an eighth left, but the player can only choose from a half, a quarter or a sixth).
- I would suggest easing into this game with simple fractions first (1/2 and 1/4).
- You also might want to start with fractions that fit in with each other (1/3, 1/6, 1/2) to make a whole.
- As the students get better at understanding fractions, you can give more difficult combinations.
