TIMS Task

    1. 11 1/20
    2. 7758
    3. 3332
    4. 54.112
    5. 815 R6 or 815 2/3
    6. 67.35
  2. The whole numbers are equal to 10, so it would be more.
  3. For 1B: 862 × 10 = 8620; 8620 − 862 = 7758

    For 1C: 100 × 34 = 3400; 3400 − 68 = 3332

X. Use Strategies

Choose a strategy to solve each problem. Give any remainders as whole numbers. Use any pages in the Student Guide Reference section.

    1. 34/5 + 71/4 =
    2. 862 × 9 =
    3. 98 × 34 =
    1. 53.68 + 0.432 =
    2. 7341 ÷ 9 =
    3. 82 − 14.65 =
  2. How did you know that Question 1A would be more or less than 10?
  3. Explain how you could use mental math for Question 1B or 1C.
