Lesson 4
Interpretemos expresiones de división
Lesson Purpose
Lesson Narrative
Students first match a division expression to a situation that it could represent. Then, students learn that the same division expression can match both “how many groups?” and “how many in each group?” problems depending on how the divisor, the number we are dividing by, is interpreted. Students then have a chance to match drawings and expressions to situations before they write their own division expressions in a subsequent lesson.
