We’re constantly asking Black athletes to step up for social justice and advance society and we have to start holding white athletes to the same standard.

@jennalaib.bsky.social @dingleteach.blacksky.app I love how creative students get with these manipulatives, and I love how much more sense-making happens when students combine these with their tasks.

Three constrictions of equilateral triangles of varying lengths.

Three constrictions of isosceles triangles of varying lengths.

In 5th grade, after quizzing my group on types of triangles I created using anglegs (asking what they notice is unique about equilateral, isosceles, and scalene triangles), they worked on a worksheet classifying polygons. After, I revisited classifying triangles by asking them to build each type.

Green anglegs are used to form an acute angle to match the angle inside an irregular pentagon.

Green anglegs are used to form an obstuse angle to match the angle inside an irregular pentagon.

Elementary math time!

More angleg action 🩵! In 4th grade, the students in my group had the idea of using the anglegs to confirm if some angles in polygons (particularly irregular polygons with 5 or more sides) were acute or obtuse. Such ingenuity!

😅. 800 ÷ 8 is a friendly relationship, and I know the quotient of 400 ÷ 8 is half of 800 ÷ 8. Then, I knew that 360 is 40 from 400, so I took away 40 ÷ 8 to get my final solution.

800 ÷ 8 = 100
400 ÷ 8 = 50
40 ÷ 8 = 5
360 ÷ 8 = 400 ÷ 8 - 40 ÷ 8
50 - 5 = 45

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!

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.
