This Instructional Activity is a part of the Lesson 11, Unit 6, Grade 7. In pairs, students explore the length requirements to form a triangle. An alternate activity that may increase accessibility is providing students with pieces of dry pasta (or other manipulatives) and rulers and then giving the task: "Build as many triangles as you can. Record the lengths of the three sides." Once students have constructed many triangles, ask, "What do you notice about the lengths of the sides?" Allow written and spoken responses.
