Today's lesson with Lou was about exchanging one set of coins for another single coin. We started simple with 10 pennies and 1 dime. My plan was to work up to exchanging dimes for 50 cent pieces and nickels for dimes. We never got there because candy won.
Me: A dime is worth 10 cents. A penny is worth 1 cent. 10 pennies is 10 cents, so 10 pennies is the same as 1 dime.
Lou: ok (her eyes were a little hazy)
Me: If you went to a store to buy a piece of candy and it cost 10 cents you could give the clerk....
Lou: How big is the piece of candy?
Me: Big! So you could give the clerk 10 pennies or....
Lou: Like a giant candy bar?
Me: Yes. 10 pennies is the same as 1 dime. You could pay with either....
Lou: Does Wal-mart have 10 cent candy?
Me: Probably not! Now listen. You could pay with either 10 pennies or 1 dime because it's....
Lou: I have 10 cents; I can buy candy.
It's official, Math is now over.
