Math in Our World: Fraction Target Game

A chalk target has 3 scoring circles. The center circle is plus 2 and 1-half points. The next ring is plus 1 and 1-fourth points. Toss 1 landed here. The next ring is plus 5-eighths of a point. Toss 3 landed here. If you land outside the outer circle, you lose 3-fourths of a point. Toss 2 landed here.

Pedro and his friends made up a fraction beanbag toss game. Each player gets three bean bags to toss each turn. After each toss, they add or subtract points based on where the beanbag lands. High score wins. There are no negative scores in this game, so if you toss a beanbag that would give you a negative score, your score stays at 0 points. The picture above shows one player’s beanbags after a complete turn.

  • Use pictures, models, or numbers to show what is happening.

  • Start with the first beanbag tossed. Add or subtract the score for the second beanbag. Then add or subtract the third score.
  • You might use the MLC Fractions or Number Line apps to model the problem.
