Unit 4, Lesson 7

Compare two quantities, and identify the greater or lesser of the two given numerals.

EngageNY 60 min(s)
In this lesson, students identify the greater or lesser of two given numbers. They first work with concrete materials, building each quantity and finding the greater or lesser number through direct comparison, and then progress to the more abstract comparison of numerals using their understanding of place value to identify the greater or lesser value. Students begin with comparing numbers such as 39 and 12, where the number of both units in the greater number is more than in the smaller number. They then compare numbers such as 18 and 40, where they must realize that the place of the 4 explains the greater value of 40.
