Truly frustrating to sit on a leadership committee & hear that the team wants to use a program that times children with math facts. It was all I could do not to flip a table. Has anybody not listened to a thing I’ve said for 8 years? It’s true- “you can’t be a prophet in your own land.”

@cmcmath.bsky.social Hey CMC—do you still come to schools and do a day of math with students? We got a grant and we’re looking to spend it? Who do I talk to? #cmc

Very excited about #KINLCon this summer. So many great sessions at such a great price. I mean… @kristenacosta.bsky.social or @jennifer-lempp.bsky.social are each worth way more than the $99 registration on their own! Check it all out here: keepindianalearning.org/events/kinlc...

my students watched a thunderstorm roll by today. They were fascinated with the lightning and thunder. I teach weather for science.. and I can’t think of a better way to introduce the unit then by seeing it in person (Southern California kids don’t see thunder storms often) #iteacheverything
