  1. True · That crossing mark is what makes a group of five easy to spot.
  2. 7 · A gate of 5 plus 2 makes 7.
  3. 8 · 8 symbols at 1 each make 8.
  4. 4 · Each star stands for one child, so 4 stars means 4 children.
  5. True · Right: 5 + 4 = 9.
  6. 3 · 9 - 6 = 3.
  7. 13 · Two gates make 10, plus 3 is 13.
  8. Four straight lines, then a fifth line if a 5th child picks grapes · A tally chart uses one line per answer, only crossing into a group once a fifth answer comes in.
  9. People might think each star means only one child · Without a key showing what one symbol stands for, readers guess wrong and miscount.
  10. True · Right: collect, then mark each item once.
