Measurement+(Grade+8)

Triangular Prism - Surface Area This video explanation is clear and the teacher does a good job explaining what a triangular prism is. The steps are also shown when doing the calculations. I believe that a student would learn how to calculate the surface area of a triangular prism. Her tone of voice is engaging and she keeps a good pace throughout the tutorial. The props that she uses are a good element for a lesson. The screen she writes on could have been more clear and she could write out her work more neatly. She also doesn't explain why the area is cm 2. She also needs to work on communicating and her math terminology.
