I just learned that our local school district seems about to decide on using the Math Vision Project materials from Utah for the next school year (I guess for CCSS Math 1 and Math 2, maybe more).
One of its main attractions is that it is all available online and free to be downloaded and printed, at least the student edition is. Maybe you have to pay for the corresponding Teacher Notes. I'm talking here about their sequence Secondary One: Integrated Pathway CCSS. There is also an Honors version of this.
I haven't had a chance yet to look carefully at this material. Is there anyone who has either used this material in a school math class, or at least studied it carefully enough to have arrived at a considered opinion of its merits and/or problems?
If so, please send me (and the group) your views on this curriculum which claims to be very closely aligned with the CCSS integrated math sequence. And then what about the Math Two version, etc.?
The Utah source of the MVP materials touts the good ratings of it that appear in the Washington state review of 7 OER math curricula. What they don't point out and what worries me is that MVP came in last in the category of Quality of Explanation of Subject Matter. Perhaps it is the case that most of the explanation is in the Teachers Edition and not in the Student Edition -- but I would view that as a problem. It suggests that the student edition is mostly just worksheets. In my very limited experience tutoring ESL students in a local high school, students need to have more than just worksheets to look at when working on homework problems -- they need some reasonable definitions with a variety of examples too. And some discussion to make it all hang together better.
