EngageNY 60 min(s)

In this lesson, students apply their understanding of tens and ones to two-digit numbers greater than 40. Students count by tens and then extra ones to efficiently count large groups of objects. Then they use the place-value chart to record quantities as tens and ones as well as by their traditional number.
