We are still using the Workbox System and it works for us. Currently Pac Man uses 9 boxes per day, which means I add in 1-3 extra items a day on top of his regular curriculum (Calvert 2nd grade). One of his favorites was this ASL file folder game I made for him. He is very into sign language, and had fun using the folder, and the book The Handmade Alphabet, to match them all up.
