Measurement conversions will be developed in this unit and revisited for mastery in Unit 8.
The Standard Algorithm for multiplication will be introduced in the third module of this unit. Please refrain from teaching this prior to its introduction, and encourage students to practice with learned strategies, as they will lead students into conceptual understanding of the algorithm and its efficiency.
A similar strategy to the standard algorithm for division (long division) will be introduced in the fourth module of this unit. Please refrain from teaching this prior to its introduction, and encourage students to practice with learned strategies, as they will lead students into conceptual understanding of the algorithm and its efficiency.
