  1. 9 · Under this key, nine pictures represent nine children.
  2. 3 · The difference is 7 - 4 = 3 votes.
  3. 5 · The bananas bar reaches 5, so there are 5 bananas.
  4. True · Without labels, no one can tell what the bars mean.
  5. 3 · Subtract 9 from 12 to get a difference of 3 books.
  6. 6 apple pictures, one for each apple · This key needs one picture per apple, so draw 6 pictures.
  7. Blue bar with 8 · Eight is the largest value and belongs to blue.
  8. False · Karl left out the fish. The total is 8 + 5 + 2 = 15.
  9. Use labels 0, 1, 2, 3 at these equal gaps · Equal gaps on a single-unit scale must increase by 1. Leo's labels increase by 2, then 3, then 1.
