Lesson 16

Escribamos comparaciones con símbolos

Lesson Purpose

The purpose of this lesson is for students to compare numbers based on the value of the tens and ones digits and read and write comparisons using <, >, or =.

Lesson Narrative

In this lesson, students use the symbols they learned in the previous lesson to write comparison statements. In the first activity, students play a game in which they make the greatest number possible by strategically placing digits in the tens place or ones place. In the second activity, students make comparison statements true using <, >, or =. Students are encouraged to read each comparison statement that they write. As students create and compare two-digit numbers and use symbols to record the results of their comparisons, they look for and make use of the structure of two-digit numbers and attend to precision (MP6, MP7).
