Every scale problem that the class has done up to this point has had measurement labels included in the scale. For example, 3 ft = 2 mi. Today we talked about how the scale can be written without measurement labels if the length on both the copy and the original are using the same measurement. For example, 1 to 20. Here is how the class was introduced to this concept.
I showed this short clip from Austin Powers to show that Mini Me is 1/8 the size of Dr. Evil.
Students then worked individually at their own whiteboards to solve these scale drawing and scale model problems.
Students finished up by taking notes to their “future forgetful selves.”
