Represent numbers 20 to 11 in tower configurations decreasing by 1—a pattern of 1 smaller.

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students work with numbers 11-19 to gain foundations for place value. They show, count, and write the numbers 11 to 20 in tower configurations decreasing by 1 to deepen their understanding of the composition and decomposition of teens as 10 ones and some more ones. Students count to answer "how many?" questions.
