**Common Core State Standard:** Know the triangle inequality theorem to determine the possible side lengths of a triangle.

**Description: **In this activity, students will discover and explore the triangle inequality theorem. It is similar to a popular activity where students are given different lengths of spaghetti and are asked to find relationships between the sides when trying to form triangles. It is a great way to still do this discovery lesson without needing the large amount of prep time needed to measure a bunch of side lengths.
