Fraction Game: My Closest Neighbor

I missed out on the adventures at Twitter Math Camp, but I’m having a great time working through the blog posts about it. I prefer it this way — slow reading is more my speed. Chris at A Sea of Math posted a wonderful game based on one of the TMC workshops. Here is my variation.

Math concepts: comparing fractions, equivalent fractions, benchmark numbers, strategic thinking.

Players: two to four.

Equipment: two players need one deck of math cards, three or four players need a double deck.

How to Play

three-eighths-of-clubs

Deal five cards to each player. Set the remainder of the deck face down in the middle of the table as a draw pile.

You will play six rounds:

  • Closest to zero
  • Closest to 1/3
  • Closest to 1/2
  • Closest to 3/4
  • Closest to one
  • Closest to two

In each round, players choose two cards from their hand to make a fraction that is as close as possible (but not equal) to the target number. Draw two cards to replenish your hand.

The player whose fraction is closest to the target collects all the cards played in that round. If there is a tie for closest fraction, the winners split the cards as evenly as they can, leaving any remaining cards on the table as a bonus for the winner of the next round.

After the last round, whoever has collected the most cards wins the game.

  1. I played a similar game with two 10-year-old boys I was working with last summer and they asked to play it every day. But ours only involved comparing fractions to each other. I love the different rounds, and the fraction number sense this game promotes! I’m hanging on to this one.

    1. Hi, Amy,
      My math club kids have played Fraction War, which is similar to what you describe. But I agree with you, the extra features of this game make it special. It’s cool to watch the synergy when teachers get together.:)
