Here are some ESL games and activities that can be used with sentences/Q&A. An example of Q&A is: "Where is the ____ (ball, book, pencil?" "It's on the _____ (desk, chair, table)." Almost all of the games and activities here will work well not only with practicing sentences, but with the substitution style Q&A.
I recommend learning and using the highlighted activities first as they are efficient, fun and educational when used properly. Pass the Bag is pretty good too. Make a sentence is really good, but requires more prep.
