  1. A student needs to find 3/4 of 24. What is the correct answer?

    Answer: 18

    To find 3/4 of 24, multiply 24 by 3 and divide by 4: (24 × 3) ÷ 4 = 72 ÷ 4 = 18.

  2. Which of the following shows the numbers in order from least to greatest: 0.5, 1/4, 0.75, 1/2?

    Answer: 1/4, 0.5, 1/2, 0.75

    Converting to decimals: 1/4=0.25, 0.5=0.5, 1/2=0.5, 0.75=0.75, so the order is 1/4, 0.5, 1/2, 0.75.

  3. What is 15% of 200?

    Answer: 30

    15% of 200 = 0.15 × 200 = 30.

  4. A student calculates 7 × 8 and gets 54. Which strategy would best help the paraprofessional correct this?

    Answer: Have the student skip-count by 7s up to 56

    Skip-counting by 7s builds conceptual understanding of multiplication and helps the student arrive at the correct answer of 56.

  5. Which of the following is equivalent to 2/5?

    Answer: 6/15

    Multiplying both numerator and denominator of 2/5 by 3 gives 6/15, which is an equivalent fraction.

  6. A student is solving 248 + 376. Using place value, what is the correct sum?

    Answer: 624

    Adding ones: 8+6=14 (write 4, carry 1); tens: 4+7+1=12 (write 2, carry 1); hundreds: 2+3+1=6; total = 624.
