Just found another great site, Activity Village. Activity Village has coloring pages, home school resources, educational resources, kids crafts, puzzles, printables, Sudoku for kids, recipes, and so much more. There are over 3000 pages of activities to help you keep your kids busy.
One of the things I found at Activity Village is their printable handwriting and story paper. I have to tell you, story paper isn't easy to find. You'll probably have to go to a teacher store to get it and then do you really want to pay their prices? It's probably easier and cheaper to just print out the few pages you'll need.
Hope you enjoy this site!
