Use scavenger hunts. Make a list of 5-10 three letter words. Hand the child a basket. If they can read the words and bring the items they get to pick an item from the prize basket (raisins, small gift). Work up to longer words.
Have child read loud from the bible or Dr. Seuss books.
Begin copy work. Short passages from the bible or bible stories.
Continue with addition / subtraction using any manipulative you can find.
