Study Jams! Area of a Triangle

This Study Jams! Area of a Triangle interactive also includes:

Even though there is a wide variety of different triangles in the world, knowing a single equation allows us to find the area of each and every one of them. Follow along with this step-by-step presentation as Zoe clearly models how to use the base and height of a triangle to calculate its area. Including two guided practice problems and a brief multiple choice assessment, learners are presented with a variety of contexts for applying this new skill. View this video during whole group instruction or assign it as an in-class or homework assignment to supplement a lesson on finding the area of triangles.
