Do-A-Dot Letter Printables- she has uppercase and lowercase! We didn't have the dot markers, but we had some small foam cylinders we had bought in the Target dollar spot that worked great for this. Could also use those garage sale stickers- GREAT fine motor activity!!
The Stay-at-Home-Mom Survival Guide: Preschool Activities This is a GREAT site. She has so many clever and easy ways to work with your preschooler and have fun at the same time. They also have infant and toddler activities.
