@howie_hua I would first subtract 3 from each side and get 998-430=568

It's Mental Math Monday with guest Dr. Peter Liljedahl! How would you mentally calculate 1,001-433?

Had a great time presenting at @MidSchoolMath. Thanks for putting together such a great conference.

Listening to @pamseda1 at @MidSchoolMath discuss the importance of have a clear vision for math success. Pushing for vision 2!

Looking forward to presenting tomorrow at the @MidSchoolMath conference tomorrow. Should be an exciting day to find out who is smarter than AI!

@robertkaplinsky When will the UC system start realizing that technology is not something to avoid but rather use as a tool to build deeper understanding?

I think we spend too much time teaching skills that are instantly useless because of technology. I wonder what might happen if we still taught number sense but didn't teach the procedures that a calculator can do. robertkaplinsky.com/didnt-teach-ca…

@howie_hua 💯

Roses are red Violets are blue Why is calc 3 Easier than calc 2?

What an amazing day @StocktonUnified for math. We were lucky enough to have both @howie_hua and @TheMathGuru! Amazing day of learning and cannot wait to work with you both again soon!

@howie_hua Either behind the back ( red shirt) or the last catch.

My 15 hardest rifle tosses. Which is your favorite?

Tell me the number that is biggest then this 99.9% will fail

@howie_hua Nice combo video - math meets color guard.

A quick way to see if a number is divisible by 4

My daughter is loving her @taylorswift13 holiday gift!!

@howie_hua And her brother Geo Metry.

@howie_hua How about Polly Nomial

I bet no one can find a beautiful sounding name that's based off a math term. Actual mathematician names don't count. I'm talking about literal math terms. None of our terms sound good as a name.

Had a great time presenting at @CAMathCouncil north (Asilomar) - Are you smarter than AI. Best memory was when one of the participants said that one pen made no sense for BTC and was sitting right in front of @pgliljedahl. Looking forward to next year already!

Happy Thanksgiving! Wishing everyone a chance to relax, reflect, celebrate what you have and spend time with family!

#calmscs #cs2025 this is what an engineering lab should look like!

@TheMathGuru @NCTM @MathEdLeaders @IowaMathTeach @region13 @ASCD @CAMathCouncil @ATMNE_math @amtnj Crossing my fingers for the Jan 2026 Stockton Tour 🙂

👀 The #MathTherapy tour starts next week! What city am I seeing you in this fall?! 🗺️👇

Getting ready to show Counted Out to the local community. So far we have shown it to approximately 250 people and hoping for at least another 100. @VickiAbeles #countedout
