This Little Piggy Went to Market Ms. Stephanie Berry Second Grade Mathematics

Directions Hi, I’m Ms. Pinky. Today I’m going to the market. I’m taking a list, a grocery sack, and a $20 dollar bill. I have to get everything on my list without exceeding my $20 limit. Will you come along to help me manage my money today?

Question #1 We’ve put everything that was on my list in the cart, but I’d like to buy some apples while I’m here. Grocery item Price Quantity milk $2.25/gallon 1 gallon eggs $1.50/dozen 1 dozen butter $1.50/lb 2 lbs. bread $1.50/loaf 1 loaf cans of soup $.50/can 6 cans sugar $1.50/lb. apples $2.00/bag ? bags How many bags of apples can I buy with the money I have left over? A. 6 bags C. 4 bags E. 1 bags B. 3 bags D. 2 bags F. 5 bags

Not quite… Oops, there’s still enough money to buy a few more. Remember, we have $20 to spend. Don’t forget: You have to add up the total price of everything that’s already in the cart. Then, subtract the price of the apples from what’s left. Remember that we got more than one of some items. Let’s try one more time.

Too many… Uh-oh, that’s a few too many. Remember our total has to be less than $20. Don’t forget: You have to add up the total price of everything that’s already in the cart. Then, subtract the price of the apples from what’s left. Remember that we got more than one of some items. Let’s try one more time.

Correct! We just added two bags of apples to our cart! Our total was $14.25. If each bag of apples costs $2.00, then we have just enough money to buy two bags of apples. Our final merchandise total is $18.25.

Question #2 The cashier has scanned all of our items. After a sales tax is added, the total is $19.35. Which combination of coins should the cashier use to give me the correct amount of change? A. B. C.

Not quite… Uh-oh, that’s not quite enough; We should get a little bit more back from the cashier. Keep in mind: A quarter equals 25¢. A dime equals 10¢. A nickel equals 5¢ A penny equals 1¢. Let’s help the cashier try again.

Too much… Oops, that can’t be right; the cashier gave us too much money. Keep in mind: A quarter equals 25¢. A dime equals 10¢. A nickel equals 5¢ A penny equals 1¢. Let’s help the cashier try again.

Correct! If you subtract the total, $19.35, from the amount of money we have, $20.00, we would get 65¢ in change. One way of making 65¢ is with two quarters, one dime, and a nickel.

We did it! Thanks so much for your help today! I know I couldn’t have done it without you! I can’t wait until we can go to the market again!
