Making inferences is a skill with which students often need much practice. If you've looked for resources in the same places that I have, you probably haven't been too happy with what you found. I believe that the inference worksheets that I've created are of a higher quality than the other available resources and, as usual, I'm giving them away for free. I hope that you'll appreciate these inference worksheets and that your students may better this valuable reading skills.
I recommend that teachers assign the online versions of these activities. Students get instant feedback, have the opportunity to improve, and are still required to answer the open-ended questions. Feel free to leave a comment if you have a question or need further clarification about any of these worksheets.
