In #Mathstoday, my 11th grade (Y12) precalculus class started series/summation. We did sequences in Jan/Feb, are are coming off of limits. I gave them these photos/problems to introduce sums & motivate and introduce sigma notation. (Photos by me and a friend) 1/3 docs.google.com/presentation...

As @mr-man-maths.bsky.social has covered International A-level Maths syllabi offered by Edexcel, Cambridge and Oxford AQA, I'd like to cover the local A-level syllabi that are taken in various countries just to see the differences in content and expectations. This is part 1 of the series.

My 8yo, learning about multiplication: 1 is the mother of every number. #tymyk

Not knowing anything else about the situation, I'd guess that Duke was #2, and #5 Michigan beat the #1 team.

Welcome to the Winter Olympics don't ask about how many people died or were injured in the making of this sport please and thank you.

In #mathstoday, I motivated z-scores by asking who was faster - Michael Phelps or Usain Bolt? In past years, I had done this after introducing z-scores, but starting with the question prompted great discussion: "You can't compare them. They're different sports." www.desmos.com/calculator/d... 1/5

Please do not use AI to grade. If demands on your time are such that you cannot provide students with timely and substantive feedback, that is a labor issue, and you should join your union. open.substack.com/pub/marcwatk...

Question for @amplifyeducation.bsky.social. Is there a way to see which assignments I have assigned to a given class?

Hey #MathEd folks, I'm looking for resources to supplement my #stats class - videos, articles, etc. that: -provide real-world examples of the concepts in action -discuss the development of concepts/tools -describe concepts and tools in intuitive or animated ways -etc. #iteachstats #iteachmath

Whenever rich men known to be liars—and exactly the sort of people who'd never give up any power granted to them—claim that they're telling the truth and are extremely willing to give up any power granted to them, there's something endemic in major media that seems predisposed to accept such claims.

This changes everything! (Well, many things.)

Dishonest charts are coming from all directions, and they're only going to hit harder. Unless we push back. So, an interactive guide: Defense Against Dishonest Charts flowingdata.com/projects/dis...

Senior U.S. District Judge John Coughenour: “It has become ever more apparent that, to our president the rule of law is but an impediment to his policy goals, the rule of law is, according to him, something to navigate around or simply ignore, whether that be for political or personal gain."

Auschwitz was at the end of a long process. It did not start from gas chambers. This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.

Just because AP courses are hard doesn't mean they're good. 25 years ago I wrote about how we confuse those 2 things: is.gd/mfScd4. (Much earlier, Dewey said the value of what students do “resides in its connection with a stimulation of greater thoughtfulness, not in the greater strain it imposes.")

Question for #MTBoS #iteachmath: What are your favorite websites to go to for either (1) Warm Up activities or (2) 3-act math tasks? Some of the sites I've used over the years have moved or are no longer active. So trying to get some fresh ideas and update my list!

Increased reliance on ChatGPT was associated with higher levels of procrastination and memory loss, and a negative impact on academic performance, as reflected in students’ grade point averages.” www.psypost.org/chatgpt-link...

The best way for higher education to confront generative AI is to train humans to think like humans. That way, when it becomes inevitable that we have to use AI, we'll have a human foundation for it. But we've been teaching students to think like machines for decades. AI just makes it easier.

Nice resources in this thread!

Not every student's test gives me the feels like this, but it's nice when one does. #iteachmath #mtbos

🤔 Challenge for #iteachmath teachers this week. 🤔 Make sure when you choose your "fun activities" for the week, that they are ALL related to math. There are plenty of things out there. Maybe we can share some of our mathy games and activities for this week. REPOST and SHARE

When making winter decor or activities for my classroom, one question I ask myself is: would I still use this after winter break? If the answer is no, it’s probably more holiday themed than winter themed. #EduSky
