This is a very well-organized VoiceThread. You have covered all the points very well and have used some good sources to support your work. You describe a wonderful blend of UDL and DI, but then, I have to ask you: How does a teacher have enough time to do all this kind of work? How do you see that you can continue to design and differentiate on an on-going basis, particularly if you have 20 or more students in a classroom?
