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 support this work by building a Rekenrek to 20, which they will use to count and model numbers for the balance of the year. Students track their work by drawing a corresponding picture to show the groups of 5 they create on their Rekenrek.
