Multiplication toss

Instructions

• Players take turns to spin the spinners.
• If a 3 and 6 are spun, players can enclose either a block out of 3 rows of 6 (3 sixes) or 6 rows of 3 (6 threes).

• The game continues with no overlapping areas.
• The winner is the player with the largest area blocked out after 10 spins.
• Eventually the space on the grid paper gets really small.
• Then, you have to think:
  • What if my 3 sixes won’t fit as 3 sixes or as 6 threes?
  • Players can partition to help them! So, for example, I can rename 3 sixes as 2 sixes and 1 six (if that helps me fit the block into my game board).
