If the class is required then by all means give advocacy a try. Perhaps bring in examples of materials your son would enjoy working with - books, worksheets, whatever you can find on the Internet or the 'teacher store' that looks about right for your son.

You can ask that your son be given something from the materials you provide while the rest of the class is coloring.

Worth a try
