Watch as students solve and then discuss an Equal Groups/Group Size Unknown problem. A student uses a level-3 multiplication and division strategy to simplify the problem and make solving it easier.

The video shows:

  • Practices that engage students in solving Equal Groups/Group Size Unknown problems.
  • One student decomposing the dividend to complete division with more familiar numbers and a second student describing the process he used.
  • How using a Groups Unknown problem encourages students to identify simple equations to solve problems.
