My first grader is pretty much a perfectionist. She also LOVES doing any type of work and never seems to be ready to move along to the next assignment. She will spend so much time making sure everything is perfect. This is opposite of my son who rushes through everything. He does his best to get out of any type of work.. I'm having problems telling one of them to speed up and it doesn't need to be perfect while at the same time telling the other one to slow down and put forth a good effort. I promised my son when we started homeschooling I wouldn't use a timer. This is what actually ended up turning him off of learning in public school. Things moved fast there, and he grew frustrated. But, I think this might be the only way to get these two on pace.
