Fraction Game

Years 3 - 6

Maree Anderson, Bev Sharp, Caroline Miller, Geeveston District High School

Equipment

  • Pack of 'cards' marked with related fractions (eg: 1/2, 1/4, 1/5, 1/10, 1/20 - two or three of each makes a good pack)
  • Red Poly Plug board masked to the appropriate size for these fractions; in this case five rows of four
Whole of Twentieths
The Twentieths Game could, and should, be played with both of these wholes. Another Twentieths Whole

Rules

  1. Players prepare their personal red board as described.
  2. Shuffle the cards and place face down.
  3. Players take turns to select a card.
  4. The card says the fraction of the whole to fill with yellow/blue plugs,
    eg: if 1/4 is chosen, 1/4 of 20 = 5, so five holes are filled with plugs.
  5. Continue until the whole is exactly filled. Remembering each time that the fraction refers to the original whole, not the unfilled spaces in the board.
  6. When the cards run out, shuffle and continue playing.
The winner is the first to fill the whole.
Twentieths Game
This person has selected one card showing 1/4 and another showing 1/10.
