Preschool programs

[mom-in-alberta]

I don't know how helpful it will be, but do you really need to purchase something?
I know that there are a number of sites out there that have the preschool curriculum posted, with various activity suggestions. It may be slightly more work in terms of researching online, but if I was going to do a full-on "program", that's how I would do it!
But let us know what you find out, as I am still curious and open-minded.
