I think I know a lot of things and then I had an interesting conversation with a 1st grade student at last night’s math night. She explained how to bond numbers so that you combine them to become bigger. The most valuable part of this math interaction was that it challenged the way I think about addition and the diverse approach to a common problem. There was a conceptual understanding that I had not considered. Who knew!
With all due haste, do not miss any opportunities to push your thinking. Collaborate with a student, colleague, family. The lessons learned are thought provoking and very satisfying. Run!
