In order to complete your PUD, you should complete two unit forms to show the integration of two different subject areas for one week of instruction. Create a week-long unit for each subject area that you have chosen and demonstrate the integration between the two subject areas. Remember, your units should also demonstrate accommodations for your students with disabilities. Some examples of accommodations include: assisted technology, note taking, test taking, graphic organizers, trade book alternatives, memory strategies, and behavior strategies (such as self-monitoring, contracts, etc.). You can come up with the subjects that you feel is easier to do that intersect. here is an example in this link.
