I teach math and statistics. I love what I do. I have some very smart and cool friends.

If you love math and/or tech and/or crafting then come to my free online Illustrating Mathematics seminar talk this Friday 🧮💻🧶

LA people, how are your non-LA parents handling the hurricane/storm? My mom called me to tell me to get to higher ground and remind me I'm "not that great of a swimmer"

@ilana_horn @theferocity @samsanders @zachstaff I love sam sanders

[Bill Thill @roughlynormal]

@ilana_horn And scaling up in two dimensions too!!

[Bill Thill @roughlynormal]

@LasCulturistas Yay!! I was starting to feel like a Karen.

@howie_hua 50 percent of 18! 9 !

[Bill Thill @roughlynormal]

@benjamindickman @fawnpnguyen @mrburkemath TWICE might be a good sorting word?

[Bill Thill @roughlynormal]

@mpershan 90% success on assessment of standards. 10% on “daily work,” which involves responses to homework prompts, homework quizzes end of unit notebook checks,

@jaycaspiankang I think you probably picked the researcher who is the MOST focused on supporting teachers’ professionalism and judgment out there. This is a great opportunity for you to engage further with us to understand why your assertion about the authors is so off.

[Bill Thill @roughlynormal]

@ilana_horn It seemed that even the author knew you were not making the claims he was “refuting.”

[Bill Thill @roughlynormal]

@mgolding @Dsrussosusan getting students to unpack and evaluate claims about how to re-express expressions with logarithms and exponents: “J claims that this re-expression is an identity… Show why they are (in)correct.”

[Bill Thill @roughlynormal]

@cluzniak … if there is no linkage, then how does every student develop the skills and understanding?

[Bill Thill @roughlynormal]

@cluzniak I would be curious to have participants connect “practice to better develop skills, understanding and retention in math” and “requirements in class we grade.”

[Bill Thill @roughlynormal]

@howie_hua Okay; 5:50, 6:50, 7:50, 8:50… back up a half hour, 8:20am! 2.5 hours. Add 12 hours —> 14.5 hours.

[Bill Thill @roughlynormal]

@averypickford I would have probably explored writing, applied statistics, and done more traveling instead of working.

[Bill Thill @roughlynormal]

@averypickford absolutely

[Bill Thill @roughlynormal]

@sig225 I didn’t see you! we’re you at my end of year meetings?

@StudyMaths if all the segments in the intermediate stages are horizontal or vertical (parallel to the bottom base or left side), then we do nothing to the overall perimeter. when we replace any of those two segments with a diagonal, we reduce the distance between two points.
