Worked examples

Read through these first, then try the practice below.

  1. Example 1 — One symbol = many items

    In a chart, one tree icon stands for 10 trees. A row has 4 full tree icons and 1 half icon. How many trees does the row show?

    Solution: 4 full × 10 = 40, plus a half icon = 5. Total = 45 trees.

  2. Example 2 — Comparing two rows

    Team A has 3 full tree icons; Team B has 5 full tree icons. Each icon = 10 trees. How many more trees does B have?

    Solution: B has 50, A has 30, so B has 20 more trees.
