The Florida Department of Education has written this one-stop manual for special needs students that includes information on various types of disability, such as visual or hearing impairment, definitions of terms, and summaries of the relevant laws. It is applicable for teachers in other states as well.
I found this site to be a great place to find information on various types of disability along with a few strategies to try for each. You can click on the links for your student's disability and learn more about what it means, what you might see in your class, and what you should try to help support your students.
Here you will find information regarding different types of disabilities and different types of accommodations. You can use this to make sure you and the school are providing the necessary strategies to help your students be successful.
This is a quick and easy read that is actually packed with a lot of information. It gives you a brief description of different types of disabilities and shares strategies that you can use for various students.
While this article doesn't include classroom strategies, I really like the way it divides disabilities into four easy-to-understand groupings: input, integration, storage, and output. These groupings will help you design lessons to help your students reach their potential.
Teachers cannot be experts on every type of disability, so you may want to use this site to research your student's specific disability. It will provide you will valuable information to help you understand the issues surrounding any disability.
When you need information on the classroom environment and how it impacts your special needs students, take a look at this resource. Plus, it includes some valuable strategies and other information on planning your class and schedule.
