Answer Key
  1. Answer: C) 2,000 mL. One liter is 1,000 mL, so 2 liters is 2 × 1,000 = 2,000 mL.
  2. Answer: C) 300 gallons. 30 gallons each minute × 10 minutes = 300 gallons.
  3. Answer: 206 gallons. 1,236 ÷ 6 = 206, with no remainder.
  4. Answer: 240 minutes. One hour is 60 minutes, so 4 × 60 = 240 minutes.
  5. Answer: 5,800 gallons. The hundreds digit is 8, and the next digit 4 is less than 5, so round down to 5,800.
  6. Answer: 6 full loads, 4 barrels left over. 52 ÷ 8 = 6 remainder 4, since 8 × 6 = 48 and 52 − 48 = 4.
  7. Answer: To hold water up high so it flows with pressure to homes. Accept any answer noting the tower stores water and uses its height to push water through the pipes.
  8. Answer: 1,650 gallons. 900 + 750 = 1,650 gallons.
  9. Answer: The nearest thousand. 5,847 rounds to 6,000 when rounded to the thousands place, because the hundreds digit 8 is 5 or more.

Differentiation

Support

Allow a multiplication chart and a place-value chart during the quiz. For items 3 and 6, give students a worked example of a different division problem at the top of the page so they can follow the steps.

Extension

Ask students who finish early to write one more computation item for the Halesford unit, complete with an answer key entry showing every step, that another student could solve.

ELL supports

Read each item aloud and provide a picture for the water-tower item. Give a sentence frame for item 7: "A town stores water in a tower so that ___."
