Direct comparison is comparing using the object itself as the unit of comparison. Indirect comparison is using another object to measure it.
As I watched the pizza example in the video, I realized how uncomfortable I am without a formula. I immediately wanted to crunch number rather than use spatial reasoning. I was taught math through formulas rather than through the development of number sense and that’s how I initially taught math. However, there were so many students I encountered who can’t memorize and for whom that old school approach was/is not effective so I am loving the idea of building number sense and problem-based learning. I do have students like me, however, who just want to put numbers together so I appreciate having great examples to use such as the ones you provide. I really think it will build better than understanding in the long run.
