I really adore this series from Linguisystems. I've used it beyond just my kids who have social needs as a way to progress check my younger language kiddos. The social stories come in four parts (so, you get a nice and clear beginning, middle, and end). A workbook comes with the series that offers you yes/no questions, "wh" questions, open ended questions, and more to ask the kiddos afterward to check for comprehension.
