Introduction
Share the Headline Story with the class. Encourage students to find creative ways to draw conclusions about the number.
Headline Story
My number is a multiple of 30. It is greater than 104 but less than 209.
Possible student responses
- Because the number is a multiple of 30, the ones digit must be 0.
- The number must be a 3-digit number.
- The multiples of 30 with 1 as the hundreds digit are 120, 150, and 180. The next multiple of 30 is 210, but 210 is greater than 209, so that can’t be the number.
