EngageNY 60 min(s)Support for English Language Learners

In this lesson, students create right angles through a paper-folding activity. Students use this right angle to learn about acute and obtuse angles and then identify the three types of angles in their environment. Finally, students draw acute, right, and obtuse angles using a straight edge and rays.
