@mrkitmath.bsky.social Is there a video of you doing a Connecting Representations activity? I seem to recall watching a nice session you led with kids...something about ratios. If it was you, could you provide me a link? Thanks!

This story is crazy. It would appear Trump admin officials rigged their nationally televised high school civics contest to keep a young man from a Sikh family out of the finalists. www.notus.org/national/ame...

America’s finest young scholars competed to mark their country's birthday. It led to a disputed finish in the age of mistrust.

Video appears to show no damage to the vehicle of the man ICE killed in Houston, who had lived in America peacefully for 35 years, despite ICE's claim that he "rammed" an ICE vehicle and "tried to run over" an agent. These people are not credible.

The players should’ve been focused on the game and their opponent, not forced to think about the president’s intervention into the tournament and reactions to it, or worry about what they’ll say if a reporter asks about it. It’s not politics to say Trump had a negative impact, it’s sports analysis.

"If you don't know how to explain a math concept using barely any words, then you probably also don't know which words to use to explain it verbally." #MTBoS, is this true? I have been leaning toward believing this is (mostly) true.

Wherever possible, I like to check for prerequisite knowledge in a meaningful way. Here's a simple one for completing the square.

A slide saying "Fill the blanks with integers."
Then underneath the following questions:
50 = 7² + ___
50 = ___² + 41
50 = 6² + ___
50 = ___² + 49
50 = ___² + 25
50 = 8² − ___
50 = ___² − 50
50 = ___² + 34
50 = 2² + ___
50 = ___² − 31
