Read the problems, and answer the questions. Explain how you can solve the problems without actually doing the skip counting. What do you know that will help you?

  • 1 Ms. McCoy's class counted by 20s. How many people counted to get to 300? How do you know?

  • 2 Mr. Harris's class counted by 10s. How many people counted to get to 300? How do you know?

  • 3 Ms. Gomez's class counted by 25s. How many people counted to get to 300? How do you know?

Students have been finding the multiples of given numbers in a routine called Counting Around the Class (for example, 20, 40, 60, 80, …). Here, they practice finding a series of multiples of a number.
