This is a set of 27 scales, one for each of the 27 Florida Standards Math Standards. These scales reflect any and all changes between Common Core and Florida Standards, including the new standard of MAFS.2.OA.1.a. These are 0-4 scales, with 3 being the proficient level of mastering the standard. I have each of these 27 scales listed for sale individually in my store. However, by purchasing the entire set at once, you save 50%! :) That's the equivalent of paying only $1.00 for each standard's scale. :) Please check out my numerous other scales (other grades and subjects) as well.
