Compare The Size Of The Product To The Size Of The Factors (Continued)


Description

Students compare the product to the size of one factor, given the size of the other factor without calculation (e.g., 486 × 1,327.45 is twice as large as 243 × 1,327.45 because 486 = 2 × 243). This reasoning, along with the other work of this module, sets the stage for students to reason about the size of products when quantities are multiplied by 1, by numbers larger than 1, and numbers smaller than 1.
