My new favorite method for practicing #French: I read Percy Jackson in French and translate out loud to English in real time as my 10 yo follows along in the English text and corrects me as I go. I mean the first chapter is about vaporizing his math teacher by accident so we’re off to a good start!

Math friends - Amplify Desmos Math has just opened up applications for their next group of Fellows. Being a Desmos Fellow has been the best PD I have done in 25 years. It’s an incredible community. Please consider applying! #mtbos #ITeachMath amplify.com/desmos-fello...

A revelation that hit me during my conversation w/ @pernille.bsky.social is the tension & pressure of training American teachers to be superheroes needed to rescue kids from failing economic systems while ignoring those systemic failures. The demand to be superhuman is ultimately dehumanizing.

I wanted to share a few student work examples of the Math Language Routine #StrongerAndClearer that show how much of an improvement there can be without the teacher giving any feedback, from both language learners and English fluent students. bit.ly/4f92vJN #UDL #iTeachMath #MTBoS #edusky

I handed out a copy of hand-written worked solutions for a task. Student quietly to a friend: "what kind of name is 'Exemplar'?!" 😂 #iteachmath #mtbos

What I don't understand is how the United States spends 154 hours on math instruction each year, 20hrs more than the international avg, & 40hrs more than high scoring EU countries like Finland & England. In fact, you'd think there was an inverse correlation between instructional time and outcome. 😵‍💫

In #mathstoday we reviewed Pythagorean Theorem. I used a #desmos activity that worked pretty well. I started with two proof without words puzzles adapted from @mathtechcoach.bsky.social as a way to ground it visually and built from there. teacher.desmos.com/activitybuil... #iTeachMath #MTBoS

Wow, the mathematical thinking that my little guy is doing while staying up late organizing his baseball cards into various categories is really fun to watch. He just reasoned his way into locating his missing Juan Soto. #tmwyk

I just made a #Zukei puzzle template with correctness check in #desmos. It's fairly easy to create additional problems with it. I'll use some puzzles like this in next week's coordinate geo unit. #MTBoS #iteachmath ♾️ teacher.desmos.com/activitybuil...

I just created Blue Sky accounts for Open Middle (@openmiddle.bsky.social) and Grassroots Workshops (@grassrootsws.bsky.social). My hope is to start sharing a lot more content on this platform, so please give these accounts a follow.

When I moved to CA years ago, I lived in San Jose, and through all the people I met and the work that I did, my world view expanded exponentially. #ManuChao ‘s Clandestino always brings me right back to that time. I’m happy he’s released a new album after 17 years! music.apple.com/us/album/viv...

I want to share the #desmos fellows project I put together earlier this year. It's a 3-part sequence that moves from adding lines visually to making sign charts of factored polynomial functions. bit.ly/411q18q #MTBoS #iteachmath ♾️
