Ever have one of those days where it seems like nothing is sinking in? I try to be patient, I take the time to explain the process, and then I move to the next problem and start all over again. I've told my children that they need to think of their brains as filing cabinets. When I explain something, they need to put the memory in a folder and file it in their brain. Now I just need to teach them how to find the file when they need it.
