I have been wanting to print and try this activity with S for a long time now. MakingLearningFun.com has printable letter magnet pages. You are suppose to use them with little colored dot magnets, but I used them with our dot art markers. S has completed "S is for school" and "V is for Valentines". I plan to bind them together in a book when we finish all the letters. I like that there are several choices per letter and they also have pages to go with Brown Bear, Brown Bear and The Very Hungry Caterpillar.
