## Reflection: Grappling with Complexity Circles and Parallelograms - Section 3: Landing

Working backward to find the solution is always a good strategy. I like the idea that my students had to apply what they knew. We don't usually get all of the information needed to solve a problem and I like to hear what they think when trying to find the information needed. I also like the idea that they can't just scribble an answer down so they can prepare to leave. Seeing them make the connections was good confirmation.
