  3. Halving can be used for a division equation where 2 is the divisor.
  4. We can use known halving facts when the divisor is 2

Common misconception

Children may make errors when halving 2-digit numbers.

Recap strategies for halving from previous units prior to the lesson so that the process of halving numbers does not take over the focus of this lesson.
