If you work with children with autism, then you might know about a product made by LinguiSystems called Autism & PDD: Picture Stories & Language Activities. Most of us know them as "Matt & Molly." I love using these stories to target a variety of skills. In fact, I use them so often, that I've made worksheets to go along with them.
This product is a companion to the 9 stories targeting: Social Skills at School. There are 18 pages, or 2 pages per story. Each 2-page worksheet contains picture symbols from BoardMaker. Skills targeted may include: circling pictures from the story, answering yes/no questions, and/or answering wh-questions.
These were designed for low-functioning students with autism, but may be used with any child as appropriate. I hope these worksheets will help you to determine comprehension while giving them a visual cue. And most importantly, I hope they feel successful!
