This is a lesson that failed the first time but through years of improvements has turned into a project that students love. If you teach rational functions, definitely check it out. #mtbos #iteachmath

The Power of Iteration in Teaching
I had a reflection the other day that came from observing the work of a teacher who I’ve now coached for four years.

Anyone else still using chalk? I am one of the last at my high school and love it.

If only I had sliding boards…one can dream.

Pattern block play! #21CenturyPB #iTeachMath
The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4” sides. The first image along the bottom shows a scaled-up equilateral triangle which is used to create the regular hexagon (with 4” sides) shown in the second image. The triangle is made of 1 teal kite, 1 gray dart, 2 blue rhombuses, 2 green triangles, and 2 pink triangles. The three images on the right show the progression of the design.

A chess piece planned in @desmos.com, designed in Tinkercad, and printed on a 3D printer. I’m hoping to have my Calculus 12 students design their own chess pieces this year as we explore volumes of rotation. @edtechcocek.bsky.social #ITeachMath

Start your week with this #yohaku. Fill in cells with 9 different factors of 120 to get totals shown in each row/column. #mathsky #iTeachMath
Use 9 different factors of 120 in a 3 by 3 grid. The numbers in the top row add to 57. The numbers in the middle row add to 85. The numbers in the bottom row add to 46. The numbers in the left column add to 10. The numbers in the middle column add to 90. The numbers in the right column add to 88.

Major kudos to the student presenters at the #CMCS2025 Leadership Pre-Con. The middle schoolers were so poised, well-spoken, and knowledgeable in effective facilitation moves. Left with some great ideas for increasing engagement and accessibility. #cmcmath @cmcmath.bsky.social #iteachmath

Collection of 8 integers; the mean, median, unique mode, and range: all 8

What is the biggest possible element of the collection?

Math literacy requires more than just calculations.

Whether they’re answering complex problems on an exam or trying to understand the terms of a home loan, students often need to use “reading comprehension, along with math skills” to succeed, @drcelita.bsky.social writes.

I love the cheerful and always clear approaches that @howiehua.bsky.social shares. I'm going to show his www.youtube.com/watch?v=KAYg... to my algebra students in learning about harmonic mean. Lesson: understand the concept and the "why", then application will be clear. #mtbos #iteachmath #mathisfun
Is this a new way of finding the harmonic mean???

This morning, I got the most amazing text and it's the reason why I love the work I do. Compliance does not equal support. Real time coaching for her was me slipping her a note, not contradicting her in front of her students. But seeing her is the most important! #iteachmath #BlackEduSky #EduSky
Thank you so much note from a teacher saying she feels seen and heard

Calculated the volume of my chess pawn in Desmos with integrals as 3.92cm^3. Used a graduated cylinder to measure the displacement of the piece as approximately 4ml. Calculation confirmed! Had to hold down the pawn with the point of a pencil since it floats otherwise. #ITeachMath

Have math teachers gotten their hands on this one yet?

135 billion pound divided by, call it 350 million citizens is... Nearly double the average weight of an American adult.

They're going to kill us all.
