Hi Pamela,
You are right on target. I bet your class is one that your students look forward to. By keeping an ongoing assessment, either formal or informal, going in your class you can adapt or modify what you are doing to help keep every student moving forward. By having a variety of instructional tools available to yourself you can quickly change what you are doing to meet that student need.
Just make sure you keep some kind of record of what you did and how successful it was to that when you teach that course again you can draw upon that method again so success will be repeated.
