Mixed Units Of Time


Objective:  Solve problems involving mixed units of time.

In keeping with the previous lessons of exploration, analysis, and autonomy, today’s lesson may be a welcome experience of independence and critical thinking for students working above grade level. Students working below grade level may benefit from more support through scaffolded questioning, visual models, and explicit instruction as to how to add and subtract mixed units of measure.
