Most students can scale up by ten as they begin to multiply larger numbers and that is a great starting place for students. In this episode Pam and Kim discuss a more sophisticated way of scaling numbers in multiplication problems.
Talking Points:

  • How beginning learners will use multiplying by 10 in double digit multiplication problems.
  • How more sophisticated students deal with smaller numbers then scale up.
  • How this applies to middle school students.
  • How can Five is Half of 10 be used with more sophisticated thinking?
