I was mentally running through my day trying to decide what to share. And I thought about how great my students did at solving the balance problems I gave them today. So great they had no use for the “solve the system by graphing” method I was trying to introduce. And then it hit me, that was exactly what was wrong with my lesson – they had no need for the new tool! So thanks to this blog I now have the insight I need to tweak tomorrow and also what I did today for next year. The power of reflection.
