Reflection: Flexibility Scale Drawings - Area and Perimeter - Section 2: Explore


I actually ended up approaching this concept two ways.  I first gave the students the problem: On a blueprint, a master bedroom has dimensions 2 in by 2 1/2 inches. The scale of the blueprints is 1 in = 5 ft.  What is the actual perimeter and area of the bedroom?  I had students grapple with the problem in their table groups, and in every class at least 5 out of 8 tables could solve the problem.  So, I let students explain how they got their answer.  Then, I went into the notes and explained an alternate way of doing the problem, and let kids choose the way they liked the best.  It was actually split about 50/50 the method the kids chose - so I am glad I gave them options!
