@sage_stage Next year will be my 19th school year. 5 years ago I moved from HS math to MS math. I think about a new career every year.

Getting my kids involved in performing arts has been amazing but prob not for the reason you think.

When they start babbling nonsense so much that I can’t think I just yell “vocal rest” and everyone immediately shuts right up.

@bizarchive Is this legit?

@elizmmiller nice! Got the original hanging in my BSS classroom!

@mathillustrated @photomath While I agree that the message is vague and could easily be suggestive of cheating, I think there’s also an argument to be made here about the benefits of checking homework answers to self asses comprehension as well as having an opportunity to see a completed solution.

@mathforge Well I do graphical also. My preferred method is substitution, but I show them both, require them to do each in an assessment at least once, and let them choose which to use when they solve word problems

@susangbarber Love this book! A big change for me was giving students multiple attempts on assignments, and REPLACING assessment grades with makeups grade (not averaging the two). Now it would be hard for me to go back—promotes growth mindset and students’ use of specific feedback.

NASA only uses 15 digits of π for calculating interplanetary travel. At 40 digits, you could calculate the circumference of a circle the size of the visible universe with an accuracy that'd fall off by less than the diameter of a hydrogen atom

Students know when a teacher is real. They have a radar for authenticity. Here's 5 tips to help:
* Admit when you've made a mistake
* Say Thank You
* Don't pretend to know it all
* Listen to them
* Use humor/ stories

What else do you use?
