I was using preschoolpalace.org and printing out letter and number and other printable pages. I stopped though for the reasons mentioned, the cost of ink and paper, and now I use the flashcards. This year I am cutting big letters, number, shapes, etc. out of construction paper and we are going from A-Z from Jan.-Aug. to prepare the kids going to JK. For A I cut a carrot with a little notch so they could stamp into red paint onto the big A's and it looked like little red apples. This week for the B's we glued bubble wrap on them. Next week for C's we will glue curly papers on and so on. I've made matching shape games with velcro on the backs on a bristolboard.
