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 =.
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).
