So, why are you minding the gap? What is it exactly that you are afraid your child will miss? Reading? Writing? Arithmetic? Building missions with sugar cubes? Face your fear. Give it a name. Make a list. Then really look at that list and determine what is most important in order to give your child the educational foundation that will allow him or her to become an autonomous, self-directed learner. If that is your goal, following a curriculum and agenda created by the state (or anyone else) is counter-intuitive.
Thanks, Tracie, for the link.
