The conclusion I had in mind was actually using that final question (4.a. using right side in their daily classroom activities), then following it with where we see the right-brain with regards to some of the curricular things discussed from past readings. The more I thought about it though, the more I had trouble figuring out how exactly the right brain was able to fit in with any of those readings.
After further thought, I realized that one option would be to reread something from a past article and look at where left and right play a part in it. That isn't really conclusion-type material though...unless I simply mention that moving forward, after reading this book it would be beneficial to evaluate future readings with both hemispheres in mind.
Any other thoughts or ideas? I am sure I will have something by class time, but ideas are welcome :)
