#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!

#mtbos Today is "professional development day" at the college.
Batting 1000 on: if there's an educational gathering, *somebody* will bring up fractions as a teaching issue. Every adult ed thing, every math thing... this was an "accessibility in your courses" and as I walked in the room somebody had just said the word before anything had started.
Yes, they have my email now
