Fraction Bounce Activity

FractionBounce is a game that prompts the player to nudge a bouncing ball to land at a point on the bottom of the screen that is an estimate of a given fraction. E.g., if 2/3 is displayed on the ball, then the ball must land 2/3 the distance along the bottom.

How to play Fraction Bounce

  1. Click on the ball to begin.
  2. Use the arrow keys (or the letters h and l) to move the ball left or right during its trajectory; any other key will cause the ball to drop straight down.

If you have an XO 1.75 laptop, you can use the accelerometer to move the ball left and right.

Multi-player game

If your share Fraction Bounce, you can play with up to three other people. Players take turns choosing the fraction to play by clicking on the bar at the bottom of the screen, e.g., if you click halfway across the bar, the fraction 1/2 will be sent to all of the players.

Notes

  • Every time you get a correct answer, a smiley face is added to the background image.
  • The delay between games decreases the longer you play.
  • The complexity of the fractions increases the longer you play.
  • Once you get 100 correct answers, the bar at the bottom of the screen becomes solid.
  • You can choose between fractions and percentages.
  • You can add custom fractions.
