No, goodness, I can't "force" my ADHD kids to do anything. I save the battles for brushing teeth and getting out the door on time.
I think that learning how to read aloud well can be a good skill but 20 minutes ugh. I can't read out lout for that long. It makes my voice scratchy and it's just not fun. And PP who said that it's difficult to read and comprehend is 100% correct. It's often an either/or situation.
