Create a Handbook that you would hand out to your fellow teachers about students with severe impairment.
Review everything that was presented in your textbook and decide the things that are the most important from each disability.  Include information about characteristics, modifications, technology, or other pertinent topics.
Create a handbook with graphics and pictures that will be easy for your fellow teachers to read and use.  Think along the lines of a quick reference book.
You can create this handbook in Microsoft Word, Microsoft Publisher, or Adobe.
Be creative and think outside the box.
