Grade 5

Read the Headline Story to the students. Encourage them to create problems that can be solved using information from the story.

Martha collects pennies. She likes to put them in more than one stack, keeping the stacks equal in size, with more than one penny in each stack. With the pennies she has now, she can put them into equal stacks in more than one way without any leftover pennies. What can you say?

- If she has 50 pennies, she can put them in stacks of 2, 5, 10, and 25.
- She can’t have 5 pennies.
- She can’t have 25 pennies (there is only one way to put these, in stacks of 5).
- The smallest number she could have is 6.
