This is a freebie for you to download and try. If you find it meets your needs it there are 6 sets in the full version for only $1.00. The word lists I have used are included in the PREVIEW of the paid product.
I use the DONKEY games every day in my RTI sessions. They are a quick way to introduce (or consolidate) a skill my kids need.
You could also add the game to a Literacy Centre.
