Anglegs would have been (if I could reteach it in 8th grade)/are so good for transformations! I'm thinking back to all the times students had some difficulty visualizing a static shape translating or rotating about a point.

Is this equation true or false? How do you know? Can you justify it WITHOUT calculating either side?

Shout out to my master's program at Mount Holyoke for introducing Anglegs to me!

I would love to hear your thoughts and wonderings @martamath0901.bsky.social @jennalaib.bsky.social @amyschang.bsky.social

A protractor is shown with the longer blue line connected from the center to the 0° mark and the slightly shorter yellow line connected from 0° to 60°.

The student moved the blue leg to the 0° degree mark, and saw the 60° measurement more clearly. The student asked about why there are two numbers at each mark and tried to make sense of why subtracting 20° from 80° would give the same measurement as the reading when the legs were repositioned at 0°.

A protractor is shown with two line segments manipulatives snapped on. A long blue line segment connects from the center of the protractor to the 20° mark on the left side of the protractor. The slightly shorter yellow line segment connects from the center to the 85° mark.

I had a student build the angle from the problem. I showed the student how rotating one of the legs made the other leg move simultaneously, preserving the angle. The student was really intrigued by this. The student later slightly adjusted the yellow line to the 80° mark.

Elementary math time!

Last week, 4th grade students were making sense of angles. All the problems present angles as static images. Students were making sense of what an angle is and how to measure it. I brought in Anglegs to support their thinking and understanding - it was wonderful!

Join us in Bakersfield for the famous CMC-Central Symposium on March 13 & 14, 2026. Game Night will be epic this year.

Ford worker who heckled Trump keeps job, 'no discipline' for incident The United Auto Workers union said TJ Sabula remains employed and called out the president for making an obscene gesture toward the worker.

The Ford worker who heckled Trump during a visit to the company's plant still has his job and "has no discipline on his record," a union official said

The arrests of journalists Don Lemon and Georgia Fort are a test for every MSM member with a platform. If you are not voicing your outrage at this blatant violation of the First Amendment, you are utterly discredited as a journalist.

They are all Black journalists and Black politicians. Don Lemon and Georgia Fort are journalists. Trahern Jean Crews ran for Minnesota's House District 66B. Jamael Lydell Lundy is running for Minnesota Senate District 65.

There's no ICE accountability without ending qualified immunity.

They're murdering people. There won't be justice for the lives they've stolen, but there must be accountability.

My bill with @markey.senate.gov would ensure families can sue the agents murdering their loved ones.

The first Minnesota murder, they refused to let a medical professional help the woman they shot. The second Minnesota murder, they simply shot the medical professional.

The StarTribune live blog is paywall free:
- The man shot by federal agents this morning has died
- Several witnesses have already been transported to the Whipple building.
- ICE attempted to order local police from the scene, but O’Hara refused, sources said.

I've got a small platform, but I want to help how I can. If any educators and students in Minneapolis want to talk or write about how the ICE occupation has impacted your community and schools, I want to host you. My DMs are open. Can anonymize however much you need to feel safe.

There is evil and then there is this

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

Somebody could formulate this thought better than me, but notice how the right uses the idea of maternal protection to dismantle public health infrastructure, but disparages the women protecting their kids from ICE gangs.

Stephen Colbert on the ICE murder of Renee Nicole Good: “The message from this administration is clear. Only they determine the truth. And when their forces come to your city: obey or die. And if you die, you clearly didn’t obey. This should be an alarm bell for the entire country.”

rare to see an american politician speak in these terms and it rocks

BREAKING: ICE killed a Minnesota woman in broad daylight & there must be accountability.

But when I moved to subpoena all records & footage related to this murder, Republicans voted it down.

They've never cared about law & order or keeping our communities safe.

masked, unidentified goons who assault and murder with impunity. a literal gestapo.
