Math openers promote rigorous student thinking and discourse at the beginning of each class. Dan Finkel from Math for Love provides over a dozen free openers on his website: mathforlove.com/lessons/open… And here's his online workshop on openers: grassrootsworkshops.com/work…

Anthropic just gave free AI access to every K-12 teacher in the US via Claude for Teachers. This article examines the 222,865 academic standards built into the tool and pinpoints the most problematic spots. I wish we were building on a more solid foundation. Curious to hear other opinions on this. @rastokke @educatedandfree

Lots of people asking about the shift to permanent daylight savings. The data clearly show locking to standard is best. For mental and physical health. That am sunlight is key, But if not, then locking to daylight savings second best. Shifting back-and-forth is the worst choice.

Replying to @DrBradJohnson
If a classroom runs on curiosity, tech deepens the thinking. If it runs on compliance, tech just emphasizes the answer-getting. Technology's not the cause here—it's the amplifier.

AI can generate a lesson in seconds. It can't tell you if it's right for these students today. Teaching is hundreds of judgment calls a day: - What's the misconception? - Struggle, or step in? - Real thinking, or busywork? What's a call AI can't make for you?

Anyone can copy a prompt. Not anyone can judge the output. That's the difference between AI use and AI expertise. And it's why we built the ELF Framework. acutelycurious.com/elf-frame… #MathEducation #AIforEducators #MTBoS #ITeachMath

30+ years in math education and I'm still finding better ways to think about activity design. I created a thing and think it's the real deal. Try it for free. 👇 #mathed #iteachmath #TeacherAppreciationDay
That math activity you've used for years? It could be so much more. The Activity Makeover Tool takes any worksheet, warm-up, or card sort → 3 concrete ways to reimagine it as a richer digital experience. Free. No sign-up. acutelycurious.com #mathchat #mathed #MTBoS

30 years in K-12 Math ed. This is what I built. Retweet if you know a math teacher who needs this. AcutelyCurious.com #TeacherAppreciationWeek
Most digital math activities look interactive but ask students to do nothing more than click the right answer. That's not interactivity, it's digitized paper. Two free tools to help math teachers design better 👇 acutelycurious.com #MTBoS #iteachmath
