First, I’d like to say that the progressions documents have been wonderful for guiding instruction.  Even the more general high school documents provide helpful insights for instruction including important connections, powerful example questions, clarity on points to emphasize and equally important, those to deempohasize.

Here are a few small errors I’ve found in the Functions progression:

pg. 7, in the example in the margin, b) says f(3)=f(3), perhaps the intention was to say f(3)=f(-3) ?
pg.11, in the note after the first paragraph I believe it is a mistake in repetitions when it says “Composition and composition of functions…”
pg.18, in the last paragraph I think the word and can be omitted where it says “the tangent and function is not often…”
A minor point on pg. 5, there is reference to the “red triangle” in the image, but there is only one red line.  The triangle referred to is likely clear to readers, but could simply be shaded to make the document complete/correct.

Thank you to all who have invested time in creating these documents!
