@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.

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.

Three constrictions of equilateral triangles of varying lengths.

Three constrictions of isosceles triangles of varying lengths.

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!

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.

😅. 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.

Aristotle Ou @alongou.bsky.social · 16/02/2026

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.

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 the longer blue line connected from the center to the 0° mark and the slightly shorter yellow line connected from 0° to 60°.

Aristotle Ou @alongou.bsky.social · 13/02/2026

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.

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.

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!

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.

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. www.nature.com/immersive/d4...

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%.
