Inside a torus
A torus is a surface of revolution generated by revolving a circle in three-dimensional space about an axis that is coplanar with the circle.

The main image in the upper left corner shows a radial design created with 21st Century Pattern Blocks. The design begins with six octagons arranged around a central star. Each octagon uses the same block arrangement in the first layer. Surrounding this, a second layer consists of 6 additional octagons, constructed using a different block arrangement. The first two images along the bottom show the two distinct octagons used in the design. The first octagon is made up of 1 teal kite, 2 green triangles, 3 blue rhombuses, and 4 pink triangles. The second octagon is made up of 2 pink triangles, 2 green triangles, 2 teal kites, and 3 blue rhombuses. The three images on the right show the progression of the design.

Silly face, but excited to present at the T3 Buffalo NY 2025 Regional Summit!

Took a break from social media. Needed some time for self care.

A lot of fun mathy things to share from the past month! 😀

Why I’m Resigning from the NSF and Library of Congress I cannot participate in systems that require dishonesty as the price of belonging.

"For me, the answer now lies in refusal, the withdrawal of participation from systems that require dishonesty as the price of belonging."

Today I am resigning from the National Science Board and the Library of Congress Scholars Council.

I wrote about my decision in TIME.

We did this same problem at AMTNYS and the T3IC. All of the answers were great! I liked cutting part of the 9's out to make 3's!

May the Fourth is almost here!

The 20 Day Bluesky Challenge! Many moons ago, my friend and forever co-conspirator, Jeannie Timken and I created a "20 Day Twitter Challenge" for educators in our district. At the time, we knew a lot of teachers who were intereste...

I created this 20 Day Bluesky Challenge to help educators get started using @bsky.app for professional learning. I hope you find it useful! #EDUSky #TLSky #Librarians #Skybrarians

The last one I received was the Geometry test prep.

Should I re-sign up?

A10: not going to lie- my brain is too tired to truly sit and think about this. 😂 I'll be sitting down tomorrow morning to work it out and see the connection!

#ElemMathChat

Great idea!

Thank you so much for this inspiring #ElemMathChat!

I have gotten your newsletter for years and love continuing to learn more as well. I bring so many strategies and resources to the teachers I work with.

If I can show them even 1 thing they will implement, it has such an impact on the students in their class!

#ElemMathChat

Definitely going to look into this!

#ElemMathChat

This would be a great number talk to have with students. Or to have them prove it true or false.

A9:
A: always
B: sometimes
C: never if you put them on a number line or have 2 of the same wholes. But I could also say maybe, depending if one object is bigger than the other. I'm thinking a pizza vs a cookie.

A8:A trapezoid is a quadrilateral (a four-sided polygon) that has at least one pair of parallel sides.

So yes, it is a trapezoid! Just not a 'typical' one that'll we would see. This emphasizes the importance of vocabulary!

#ElemMathChat

Excited to share this in my Professional Development sessions!

Replace the 3 with x!
(Forgot to add that piece 😂)

7+4(x)=19

I've done this with 3rd graders and told them they are doing Algebra like high school kids. They think it's so cool!

#ElemMathChat

Yes! Those arrows connecting the various representations is so important! #ElemMathChat

A7: 3 under each splat
19-7=12
12÷4=3
