Thank you for all your work on all the Progression Documents. I have found them very helpful in planning professional development. Just something I noticed that may want to be edited on the Number Systems Progression:
On Pg. 7 at the very bottom right, there is a model showing -(-a) on a number line. The heading of that image states “Showing -(-a) = 0 on the number line”. I believe that should state -(-a) = a

Thanks again for all your hard work!
