My coworker Mike is a new mathematician today.

Seen @nctm.org this morning. I’m not there but my coworker Mike is. Say Hi to him. #iteachmath

Hey Math Friends in Atlanta. I am not there, but so jealous. Can you post pics of the sessions you attend and people and slides and...let me have an at home experience. Also, look for my MN friends there. Hang out with them. (also look for my coworker Mike Huberty in costume)

I do!

Also. Google the mathematician pictured. (Alexander Grothendieck) Turns out there is a name for numbers that are not prime but feel like they should be.

I turned 57 today! All previous posts connect to this number. Happy Thursday all. (just humoring myself)

I know some of you have been wondering about my posts in the last 12+ hours. I am just humoring myself. But I know some of you are worried - here is my proof - within a couple of hours I received these texts from my sister, brother and mom. More soon to connect all the previous posts today.

lol. Great response. But I am fully an adult.

Really close. Great guess. A bit older.

Gold star! Thanks.

My age today is NOT a prime number, BUT a lot of people think my age is a prime number? How old am I? #mtbos #teachmath #mathstoday

Heinz!

Happy Bday to you too, my friend!

Yes I made a homemade ‘Happy Perfect Square Day!’ pin to wear today. Do something that involves a right triangle today & let me know what it is. #iteachmath #mathstoday

I know three people whose birthday is today. I told them that they should celebrate at 1:04. =)

Yes. So cool.

I just learned from a math teacher that it is a day: Perfect Square Day!

And this is a special one for this century, because 2025 is 45²

1 day! Does it have to be squares off of each side of the triangle? Also, my nephews at ages 3, 4 and 5. Enjoy. #iteachmath #mathstoday #mtbos docs.google.com/document/d/1...

Correlation? Causation?

What math task? What math context? should make it into the K-12 Math Hall of Fame? Let's hear your choices! #mtbos #iteachmath #mathstoday

9 days until Perfect Square Day! I know 9/9/25 is a perfect square, but 9/16/25 hits a bit different as it connects with a 3/4/5 right traingle. On another note, I made my nephews pose for this pic when the turned ages 3, 4 & 5.

It is a dream come true. I am now a math instructor at the University of Minnesota! Ski-U-Mah!

I didn't get a job here or anything. I'm just a math instructor physically on their campus.
