The way I'm planning to adapt the curriculum is to basically ignore the math and language parts (completely replacing them) while still doing the PE, religious education, personal hygiene, character, outdoor, craft, and food activities. Since preschool curriculum is less about academics and more about life experience, exploration, and play; it appears to be easier to adapt than an elementary school curriculum. Also the particular curriculum I bought is for 4-6 year olds, so the non-academic activities are skewed just slightly older. Plus, it's designed to only be used for about an hour and a half two or three times a week. That leaves the vast majority of our time open.
By elementary school, we'll be creating a completely personalized curriculum.
amazedmom, that science experiment kit sounds great. What is it called? My son is also into the human body. Anything you've found to be particularly good for exploring that interest?
