If you have not heard of Universal Design for Learning, also known as UDL, you might want to check out my post here that gives an introduction. You can also choose Universal Design for Learning from one of the categories on the right for additional posts on this topic.
UPDATE 6/10/2020: Unfortunately, the resource below is no longer available.
The UDL Tech Toolkit is a Glog that has links to a variety of technology tools to make learning accessible to all students. Even if you have not heard of UDL, or are not ready to plunge into Universal Design for Learning full speed ahead, you will find that there are many useful resources included in this Glog. I would definitely recommend bookmarking the UDL Tech Toolkit, so that you will have a ready reserve of sites that can help you to engage students with many different abilities.
