Grade 4

Read the Headline Story to the students. Encourage them to use logical reasoning to draw conclusions about the coins.

Kyra, Martin, and Joel each have some coins. Kyra’s coins have a value that is a multiple of 6¢. Martin has a multiple of 7¢. Together, the three have 34¢. How much might they each have?

- All of the children have at least one coin.
- Kyra might have 6¢, 12¢, 18¢, 24¢, or 30¢.
- Martin might have 7¢, 14¢, 21¢, or 28¢.
- If Kyra has 30¢, then Martin would not have any coins, so Kyra must not have 30¢.
- If Martin has 28¢, then Kyra would have 6¢ and Joel would not have any coins, so Martin must not have 28¢.
- If Kyra has 18¢ and Martin has 7¢, then Joel would have 9¢.
