Even though I am not very knowledgeable about the content, I can see that the author has put a great deal of work into developing this resource. The content seems meaningful and the tool used to reach the desired outcomes is very interesting. I have not used a smartboard activity before, so I would have to actually use it in my classroom to be able to see the strenghts and weaknesses of the tool. I would suggest that you add more details to the essential content to clarify any questions other teachers might have. Additionally, I'd like to know what tool will be used for the perfomance task, if there is any.
I cannot comment on the technicalities of the lesson as I have never used a smartboard.
