When do we use skip counting in the real world?

For example, counting times a ball bounces before picking it up.

Your turn to create a missing element problem

A image of a child with a magnifying glass that shows a question mark showing a missing number in a pattern on a chalkboard.

Now it’s your turn. Create two missing element problems following these instructions:

  • the first problem shows a pattern but does not involve numbers
  • the second problem may show a pattern or be solved with a pattern but involves numbers
  • both must have a missing number or element

Record your missing element problems in a notebook or a method of your choice.

After creating your problems answer these questions:

  • How did you decide what to create?
  • Which one did you enjoy creating more? Why?
  • What strategies might someone use to solve your problems?

Record your ideas in a notebook or a method of your choice.
