Thank you, Sue!

All set up and ready for the first day of teaching this semester. Can’t wait to meet the new group of @butleru.bsky.social COE students! #iteachmath #edusky

The picture shows a classroom at Butler University. There are eight tables in the room. Three tables have table tents on them for students to create name plates. Five tables have provocations prepared to engage students in thinking about math. Tools at the provocation stations include foam cubes, Legos, game pieces, number cards, and a box of items for counting collections.

Human brains, placentas and dolphin breath all show signs of plastic pollution in the form of tiny particles known as microplastics. Here’s what to know.

Tons of Invisible Plastic Pieces Lurk in Ocean Water

A new study offers the first estimate of nanoplastic pollution in the ocean. There’s a lot.

Quick reminder to the #mtbos and #elemmathchat crews. Get those proposals in ASAP! Who’s joining @cfless.bsky.social and me in Indy for the @nctm.org Spring Conference in February?!

A photo of an email from the National Council of Teachers of Mathematics reminding everyone that proposals are due in one week: Monday, July 14!

What an amazing finish to #BTCC25. @peterliljedahl.bsky.social gave an excellent keynote, and the attendees were willing to interact with @cfless.bsky.social and me as we emceed. So grateful for this experience, and can’t wait to see everyone next year in Connecticut for #BTCC26!

Easiest job ever.

Ryan Flessner @ryanflessner.bsky.social · Jul 1

I feel the exact same way - I met the real Tammy McMorrow! It was everything I hoped it would be!

When you’re married to another math educator, it’s easy to get get lost in the work. Today, I had the privilege of watching @cfless.bsky.social in action at #BTCC25. I’m lucky to live with this incredible mind, and I’m even luckier to learn from her.

Courtney leans in to talk to two of the participants in her session. She has a big smile on her face as she listens to a woman speak. The woman next to her is taking notes on what is being said.

Ten minutes before @cfless.bsky.social’s #BTCC25 session and the room is packed. People are sitting on the floor, bringing in extra chairs, and finding spots to stand along the wall. Fact fluency is important, and Courtney Flessner is the real deal!

Court prepping her slides as people file in for her session.

Eleven rows of tables with eight chairs each. All seats are full, and people are standing along the walls.

Who knew Theresa Liljedahl was a Jenga shark? @tbrzezinski.bsky.social is finding out the hard way! Looks like @pgliljedahl.bsky.social isn’t the only one in the family with good spatial sense! The things you learn at #BTCC25

Theresa Liljedahl and Tim Brzezinski engage in an intense game of Jenga as Peter watches.

So fun to see @kmkuri.bsky.social (one of the fantastic teachers with whom I work in the Clover Park School District) at #BTCC25. Now we have even MORE to talk about during my next visit to the PNW!

Thanks to the #BTCC25 planning committee for trusting @cfless.bsky.social and me with microphones! It was amazing to emcee the opening session, to get everyone up and dancing, and to hear @pamseda1.bsky.social’s keynote. Can’t wait for tomorrow’s closing session!
