For me, it is transitioning. I am NOT good at moving from one subject to the next without a little crazy town in the middle. I feel like I have good lessons and good behavior management, but moving from one point to the next is where I ALWAYS have sorta sucked. I know they are not little robots that can put word work away and begin reading without a little hiccup. But I wish I could be better. Do you have one area you know you need to better at?
