It’s happening this Wednesday! Join me at 4 PM PT / 7 PM ET for a lively conversation about AI Math. We’ll talk about how AI can support teaching, planning, engagement, differentiation, and math curriculum. #AIinEducation #MathEducation #TeachingMath #EdTechSolutions #EdThatAddsUp

Want stronger math classrooms? Start with: • Language scaffolds • Student talk • Cultural connections That’s how we move from answers → understanding. #Math4ELs #LanguageRich #TeachingMath @Seidlitz_Ed

When students don't have to hold every step of a problem in working memory, they can focus on the math itself. This piece shares how strategy cards support stronger independent practice. buff.ly/ghMONoV #TeachingMath #EducationResource

This old Russian method shows how it should be done: transparent, logical, and respectful of the student’s intelligence. What do you think? Have you seen better (or worse) ways to teach borrowing/regrouping in subtraction? #MathEducation #TeachingMath #Subtraction

UK subtraction vs the Russian dot method: same math, very different cognitive load Take a classic UK primary-school problem: 5,000 − 236 If you’ve seen a British child’s homework, you know the drill. 🇬🇧 The UK method (decomposition / exchange) In the UK, subtraction is usually taught via exchange (often called decomposition): * exchange 1 thousand from the 5 * because there are zeros, the exchange cascades * zeros turn into 9s, the last column becomes 10 * digits are rewritten above the originals, sometimes crossed out, sometimes annotated It’s logically correct. But on paper, it quickly becomes busy. The student isn’t just subtracting — they’re also managing state: Which digit changed? Which one was crossed out? Did I rewrite that correctly? The result often looks like accounting notes, not arithmetic. 🇷🇺 The Russian / USSR dot method (Kiselev) The Russian dot method uses the same mathematics — but a radically cleaner interface. Instead of rewriting digits, the student: places one dot above the 5, marking that borrowing passes through zeros That single dot encodes the entire exchange: * 5 → 4 * intermediate zeros → 9s * last zero → 10 * subtract normally → 4,764 No cascading rewrites. No crossed-out numbers. No visual noise. The real difference This isn’t about correctness — both methods work. It’s about what the student is trained to think about: * The UK method trains careful bookkeeping of edits. * The Russian dot method trains place-value structure. One externalizes every step. The other compresses the logic into a single, meaningful mark. That difference matters — especially when problems get larger, mental arithmetic matters, or students need to reason rather than follow recipes. We’re finalized a US-focused translation of Kiselev’s Arithmetic — not just translating words, but recovering techniques that respect a student’s ability to think. Math shouldn’t look like paperwork. It should look like understanding. Learn school math properly: valeman.gumroad.com/l/arithm… #MathEducation #Kiselev #Arithmetic #UKEducation #Homeschooling #EdTech #PlaceValue #TeachingMath

Why does Slovak subtraction homework still turn into a paperwork exercise? Take a simple one: 5,000 − 236 In many Slovak classrooms (and broadly Central European practice), kids are taught the rewrite-and-borrow routine: * Cross out the 5, write 4 * Turn the next 0 into 10, then cross it out into 9 * Repeat across zeros * Sprinkle little numbers above the line like bookkeeping annotations It works — but the page ends up looking like a spreadsheet audit, not math. The student spends more effort tracking edits than understanding place value. Now compare that with the classic Russian dot method (as in Kiselev): ❌ Slovak “Rewrite/Borrow” Method You physically modify digits as you borrow: * rewrite 5 → 4 * rewrite 0 → 9 * rewrite 0 → 9 * last 0 → 10 Lots of visual noise. Lots of chances to lose the thread. ✅ Russian “Dot” Method You don’t vandalize the number. You just: * Put one dot above the 5 to mark that you borrowed through the zeros. * The logic is then clean and consistent: * the 5 becomes 4 * the crossed zeros become 9s * the last zero becomes 10 * and you subtract normally Same arithmetic. Less clerical work. More place-value thinking. That’s the real difference: One method trains editing. The other trains structure. We’re finalizing a US-focused translation of Kiselev’s Arithmetic — not just translating text, but restoring techniques that treat students like they can actually think. Math shouldn’t be a war on paper. It should be elegant.

Mastering Number Bonds to 10 is a fun and essential step in building strong early numeracy skills. When children learn which, numbers combine to make 10, they develop quick mental math strategies, boost their addition confidence, and build a solid foundation for more advanced math. ✨🧠 Whether using fingers ✋, counters 🎲, or catchy number bond songs 🎶, practicing number bonds to 10 helps make math easier, faster, and more enjoyable. It’s the perfect way to help every child see numbers as friendly pairs! 🤝🔢 #NumberBonds #EarlyMath #NumeracySkills #MathFluency #MathForKids #MentalMath #AdditionSkills #MathConfidence #EarlyLearning #MathFoundation #NumberSense #MathIsFun #MathStrategies #LearnMath #TeachingMath
