  1. 28 · 8 + 11 + 9 = 28 cm.
  2. Measure from the zero mark · Measuring comes before recording and plotting.
  3. Write down the measurement · Recording each measurement keeps track of every object's length so you can use the data later.
  4. True · One X always means one object at that length. That's how you read the data.
  5. 5 · 3 + 2 = 5 sticks.
  6. Two X's above 4 and one X above 5 · Two flowers measured 4 cm, so two X's go above the 4. One flower measured 5 cm, so one X goes above the 5.
  7. 6 · Add all the crosses: 2 + 1 + 3 = 6 objects.
  8. True · Priya is sensible. Recording first stops data going missing before it reaches the plot.
  9. He drew one too many X's; only two leaves were 5 cm · Only two leaves measured 5 cm, so only two X's belong above the 5.
  10. 7 · 4 + 3 = 7 books.
