We made the decision to stick with Abeka. Is it going to be easy? No, but I think the fluency by sticking to one curriculum will be best.
I am keeping my homemade curriculum for preschool, but it's getting tweaked a bit with every kid so far. One of the biggest warnings I had while we were choosing Abeka was the amount of seat work. You have to keep in mind that Abeka curriculum is written for their Christian school and then utilized by home-schoolers. So there is seat work written in to occupy kids while other children in the classroom are finishing their work. This doesn't mean you need to do it in your home school setting! The bottoms of the pages are labeled 'classwork, seat work, extra practice' and such along with what lesson they go along with. After reading another warning that ended up turning a mom against Abeka-which I believe is a GREAT curriculum, I decided to take a picture comparing the amount of work Eva did versus the amount of work Andrew did in a week. The pile on the left is Eva's. Her preschool was a combination of one of those books you can get from Walmart and some free printables for extra practice. Andrew's pile on the right is his worksheets and some money practice sheets off the internet because he is having some issues remembering what coins go where. I know the picture is blurry, but I think you can tell my homemade curriculum gave Eva at least twice the work in a week as Andrew's.
