I am still trying to decided what curriculum I want to use with my little 4 year old this year. I enjoy them all!
Pictures of some of last years preschool kids!
I have used the Joy School curriculum with some of my kids and I love the values and stories that it uses. The Eyre's have just revised the Joy School Curriculum and it is now call Joy School 2.0. The good news is that the new program is even cheaper than it was before.
I have also adapted the "Five in A Row" curriculum for a preschool curriculum. It was written as a homeschool curriculum, but can easily be adapted. It is based on classic children's literature and you use one book per week to teach about many different subjects.
We have most often just made up our own curriculum, there is so much available on the internet it is easy to just assign lessons like this:
Week 1: Letter A, Number 1 (animals)
Week 2: Letter B, Number 2 (balls) . . .
Another idea that some of my friends have used in the past is FunShine Express. It is more expensive, but sends you everything you need to teach preschool.
I also like the Core Knowledge book "What Your Preschooler Needs to Know."
Here is a post I wrote called, "Picking a Preschool."
