Graphs with a key: when one square means more W1-mt_r8XnXwRA6g-s1

  1. 35 · The scale increases by 5 at each mark. The next mark after 30 is 30 + 5 = 35 pets.
  2. Two groups of four votes · Each star stands for a group of 4 votes. Two stars stand for two groups of 4 votes.
  3. 5 books · The key tells you what one square is worth. Here, one square stands for 5 books.
  4. True · When every row uses the same key, more symbols always stand for a bigger amount.
  5. 18 · Reading has 6 votes, Games has 8 and Art has 4. Add every category: 6 + 8 + 4 = 18 votes.
  6. 27 · The top two are Grape (15) and Apple (12). 15 + 12 = 27.
  7. Red by 2 votes · Red has 4 x 3 = 12 votes. Blue has 5 x 2 = 10 votes. Red has 12 - 10 = 2 more votes.
  8. True · Both rows use the same key. Together they have 6 stars, and 6 x 3 = 18 votes.
  9. Multiply: 3 x 10 = 30 books · Alex added the square count to the key: 3 + 10 = 13. Each square represents 10 books, so use 3 x 10 = 30 books.
  10. 8 squares · Art needs 12 divided by 4 = 3 squares. Sport needs 20 divided by 4 = 5 squares. Together they use 3 + 5 = 8 squares.
