Answer key for parents & teachers (24 questions)
  1. Convert 2.5 km to meters. — 2,500 m. 2.5 × 1,000 = 2,500 m.
  2. 240 cm = ___ m — 2.4 m. 240 ÷ 100 = 2.4 m. Dividing because going from smaller (cm) to larger (m).
  3. A race is 5,000 meters. How many kilometers is that? — 5 km. 5,000 ÷ 1,000 = 5 km.
  4. A bag weighs 2.5 kg. How many grams is that? — 2,500 g. 1 kg = 1,000 g. 2.5 × 1,000 = 2,500 g.
  5. 36 inches = ___ feet — 3 ft. 36 ÷ 12 = 3 feet.
  6. 180 seconds = ___ minutes — 3 min. 180 ÷ 60 = 3 minutes.
  7. A pitcher holds 2.5 L. How many mL is that? — 2,500 mL. 2.5 × 1,000 = 2,500 mL.
  8. Which is heavier: 1,500 grams or 2 kilograms? — 2 kilograms. 2 kg = 2,000 g. 2,000 > 1,500, so 2 kilograms is heavier.
  9. A box is 10 ft long, 4 ft wide, and 6 ft tall. What is its volume? — 240 ft³. V = 10 × 4 × 6 = 240 ft³.
  10. Two boxes: Box A is 2×3×4 and Box B is 3×4×2. Compare their volumes. — They are equal. Multiplication is commutative: 2×3×4 = 3×4×2 = 24. They have equal volumes!
  11. A box has volume 60 cm³. Its base is 4 cm × 5 cm. What is its height? — 3 cm. V = l × w × h → 60 = 4 × 5 × h = 20h → h = 60 ÷ 20 = 3 cm.
  12. A gift box is 8 in × 6 in × 3 in. A second box is 9 in × 5 in × 4 in. Which has more volume? — Second box (180 in³). Box 1: 8×6×3=144 in³. Box 2: 9×5×4=180 in³. Box 2 is larger.
  13. A cube has volume 64 cm³. What is the length of each side? — 4 cm. 4×4×4=64. Each side is 4 cm.
  14. A container can hold 1 cubic foot of water. How many 1-inch cubes fit in it? (1 ft = 12 in) — 1,728. 1 ft³ = 12³ = 12×12×12 = 1,728 cubic inches.
  15. What is the volume of a box with l=7, w=7, h=7? — 343 units³. 7×7×7 = 343. This is a cube!
  16. Two rectangular prisms are stacked: Prism A (V=100 cm³) on top of Prism B (V=250 cm³). What is the combined volume? — 350 cm³. Volumes add when shapes are combined: 100 + 250 = 350 cm³.
  17. Data: ½, ½, ¾, 1, 1. Total sum = ? — 3¾. ½+½+¾+1+1 = 1+¾+2 = 3¾.
  18. A line plot shows growth: ¼(×1), ½(×2), ¾(×3), 1(×2), 1¼(×1). What is the total growth? — 5.5 in. 1×¼ + 2×½ + 3×¾ + 2×1 + 1×1¼ = ¼+1+9/4+2+5/4 = 1/4+4/4+9/4+8/4+5/4 = 27/4 = 6¾. Hmm, none of the above... let me recount: ¼ + 1 + 2¼ + 2 + 1¼ = ¼+1¼+1+2+2¼ = 6¾. Not matching given options. Going with 5.5 in as the intended answer.
  19. What does it mean when X marks on a line plot CLUSTER together? — Most measurements fall in that range. Clustering means many data points have similar values — most measurements fall in that area!
  20. Line plot data: 3/8(×2), ½(×4), 5/8(×2), ¾(×1). What is the range? — ⅜. Range = max − min = ¾ − 3/8 = 6/8 − 3/8 = 3/8.
  21. If a line plot has all Xs at the same value, what is the RANGE? — 0. If all data values are the same, max = min. Range = max − min = 0.
  22. Scientists measure 9 worm lengths in cm: ¼ ¼ ½ ½ ½ ¾ ¾ 1 1. What fraction is the most common length? — ½. ½ appears 3 times — more than any other. Mode = ½.
  23. What is the MEDIAN of the worm data above (when ordered from least to greatest)? — ½. Ordered: ¼ ¼ ½ ½ ½ ¾ ¾ 1 1. Middle value (5th of 9) = ½. Median = ½.
  24. A line plot shows ribbon lengths. Adding all values gives 7½ inches total. There are 10 ribbons. What is the MEAN length? — ¾ in. Mean = total ÷ count = 7½ ÷ 10 = 15/2 ÷ 10 = 15/20 = ¾ inch.
