I have used framing for Surface Area of 3D figures to break down the differences in the formula. I used it for my class as a way for taking notes and getting them more involved with understanding the different formulas and what each formula require. They would get confused on height of a triangle vs slant height. I also am using it for angles showing the difference between supplementary, complementary, and vertical angles. The students love being able to help co-construct the Frame and using it as a quick reference. I see using it more because it does only show the essential detail with examples being shown later.
