When: after breakfast (no school today!)
Where: dining room table
What you need: playing cards with images of money on them
Played a cute game called '51' from RightStart Math using their US coins card deck. It was an ok game that led to a surprisingly interesting discussion.
The game in brief:
- The US coin cards show the obverse image from pennies, nickels, dimes, quarters, and Kennedy half dollars. One side of each card has two copies (two total images) of the coin, the other sides are a common pattern (so you don't know the coin when the card is turned down).
- Players are each given 3 cards
- On each turn, a player plays a card to an open stack making a total less than 52 cents, collects the stack if they have made exactly 51 cents, or plays a card to create a new stack if their coin would cause the existing stacks to overrun 51.
- At the end of the game, compare who has collected the most cards
Here was the fun part:
Challenge 1At the end of one game, we had 90 cents unclaimed on the table.
I was initially surprised, thought for a moment, then realized what had happened. Questions I posed to J1 that I offer to you:
- Why was I surprised?
- How much did we usually have remaining on the table at the end of play?
