This lesson seems well organized and it seems to adhere well to the UDL principles overall. It is very easy to see that you used reverse design in creating this lesson and the goals are very clearly stated. My primary concern is that students don’t have many options or paths to take when it comes to demonstrating their understanding of the content. I have had any experience with flipcharts myself but would be interested to see if their was a way to incorporate and type of videocast into them for students who struggle with learning and demonstrating understanding with text. Student who might struggle with reading may struggle with aspects of this assignment. I would love to seem some technology aides incorporated such as text to talk to help those students who might not be able to handle the reading load that well. Overall I think your lesson is well organized.
