We got some sight words stickers (easy to make your own too I guess) and pasted them all over the all (DS put some up and supervised the placement of those more than 4' from the floor).

Then we would get a flashlight and play 'word power' - we would take turns illuminating a word in the dark and ID-ing it. I would let him quiz me a lot just so he did not feel like a little kid. Anyway, it is a fun and non-intimidating way to practice sight words (and you get to play with flashlights too).
