Teacher overview

Poppyfield Elementary's fictional school store sells bottled water at its snack cart, while the school's water fountain offers a free refill station for any student carrying a reusable bottle.

  2. A student buys 1 bottle a day. There are 5 days in a school week. How much do they spend in all?
  3. A refill at the water fountain costs $0. How much do you save by refilling once instead of buying one $1 bottle?
  4. Over 5 days, how much would a student save by refilling every day instead of buying a bottle every day?
  5. A student has 3 quarters, 2 dimes, and 1 nickel. How many cents is that in all?

Answer Key
  1. Answer: $4. $1 times 4 bottles equals $4 (1 + 1 + 1 + 1 = 4).
  2. Answer: $5. $1 per day times 5 days equals $5.
  3. Answer: $1. $1 for the bottle minus $0 for the refill equals $1 saved.
  4. Answer: $5. $1 saved per day times 5 days equals $5.
  5. Answer: 100 cents. 3 quarters (75 cents) plus 2 dimes (20 cents) plus 1 nickel (5 cents) equals 75 + 20 + 5 = 100 cents.
  6. Answer: Yes. 100 cents equals exactly $1, so the student has just enough to buy one bottle.
  7. Answer: 55 cents. 4 dimes (40 cents) plus 3 nickels (15 cents) equals 40 + 15 = 55 cents.
  8. Answer: 45 more cents. 100 minus 55 equals 45 cents.
  9. Answer: $12. 12 bottles times $1 equals $12.
  10. Answer: Answers will vary; accept any answer noting that a reusable bottle costs nothing to refill, so choosing it instead of a bottle every day adds up to real savings across a school year.

Differentiation

Support

Provide a printed coin-value chart (quarter equals 25 cents, dime equals 10 cents, nickel equals 5 cents) next to items 5 and 7, and allow students to build each amount by hand with play coins.

Extension

Ask students to find the fewest number of coins, using only quarters, dimes, and nickels, that could make exactly $1, and explain how they chose that combination.

ELL supports

Pre-teach "dollar," "cents," and "refill" with real or play coins and a $1 bill shown side by side. Allow item 10 to be answered orally to a partner before writing.
