My 6 year old can't sit still for long either. My best suggestion: don't make him ;) Let him have small breaks frequently, keep some snacks onhand, an abacus or stress ball to keep his little hands busy while you are reading.
My boys rented MIB2 so they are watching it. I am laid up in bed with a stomach virus, and dh is on his laptop. i think me and the hubs are fixing to watch a movie.
I use Life of Fred exclusively right now *hides* and all 3 of my boys say it is thier favorite subject. I add some problems here and there if they need more practice.
We LOVE Total Language Plus! It is all in one and I will do it all the way thru high school. It is set up by weekly units with a-e days. Read all about it here: http://site.totallanguageplus.com/
I am not in a state where we need to count days. We learn everyday, everywhere. It is a lifestyle for us. My kids are still you and LOVE learning. They ask a million questions just driving down the highway lol.
We are working thru the holidays for the most part. We might take a total of a week off. I am having surgery in Febuary so we will have 2-3 weeks of then.
