Headline Story
I’m thinking of a number. It is divisible by 5, it is odd, and it has 2 digits. What do you know about the number?
Possible student responses
- It ends in 5.
- The tens’ digit can be any digit 1 through 9.
- If you count by 5s, every other number beginning with 15 and ending with 95 will work.
