Circles & Stars

  • Player A rolls the die, then draws that number of fairly large circles.
  • Player B rolls the die and does the same.
  • Player A rolls the die and draws that number of stars in each of her circles.
  • Player B rolls the die and does the same.
  • Each player writes the number sentence that tells how many stars she has (for example, four circles with three stars in each circle would be 4×3 = 12 stars).
  • Play six rounds, then determine the total number of stars that each player has.

Variation

For each round, after Player A draws stars in his circle, determine the probability that Player B will end up with more stars than Player A.
