Lesson 11
Comparaciones usando valores posicionales (parte 2)
Lesson Purpose
Lesson Narrative
In previous lessons, students learned to compare three-digit numbers using the number line and base-ten diagrams. In this lesson, students compare three-digit numbers in tasks that do not suggest a particular representation. In the first activity, students complete comparison statements to make them true and are encouraged to explain or show their thinking in a way that makes sense to them. In the second activity, students learn a new stage of the Greatest of Them All center. This activity encourages students to reason about place value as they use digits to make three-digit numbers and compare numbers with their partner.
