EngageNY 60 min(s)Support for English Language Learners

In this lesson, students classify three-sided shapes by identifying them as examples of a rectangle. First, students make a connection between the name and attributes of a rectangle. Then they work with various examples and non-examples of triangles, sorting and classifying different shapes as examples of a rectangle or not a rectangle. Finally, students create their rectangles with Wikki Stixs and dots.
