#mtbos and in the "let's use nice language to limit opportunities," the "Strong Start To Finish" folks write that "almost no one needs college algebra anymore." Also, states are "resdesigning developmental education."
Once more, how about at least *looking* at why students are getting through high school without the math skills? SHHH.

#mtbos so I think I figured out that my Moodle class ... well, you just can't really sign up with your email. (Perhaps something's built into my site architecture for spam control.) But if you know somebody who wants to try a conceptual, little bit at a time, number sense based "course" https://resourceroom.net/class/ will get them there and I can sign them up :P NO cost or commitment... even figuring out how to get signing up to work is helpful.

For now, it will be a times tables class to see if it works!
