Excited and looking forward to present @SnorklApp AI in the Math Classroom with @PlateKaitlyn @LHRICit's #TechExpo2026 #WeAreChappaqua @LH_RIC #EdTech #ITeachMath #MTBoS #STEM

Excited about The #WorldCup2026?! We are, too! That's why we can't wait to share our Soccer & STEM playlist, made up of seven brand new videos that all frame STEM concepts through the beloved game of soccer. Teachers and students at @CityLabHS, the Innovation, Design, Entrepreneurship Academy (@IDEA_at_Fannin), @UpliftEducation, and the William B. Travis Academy (@travis_tag) created this series of videos to help learn about the hidden geometry, algebra, and physics behind corner kicks, penalty kicks, the field’s turf, and more. Check out the full YouTube playlist here: youtube.com/playlist?list=… And read our latest blog post for information: talkstem.org/world-cup-mani… #ITeachMath #STEMEducation #PhysicsInSports #MathIsEverywhere #ScienceEducation #HandsOnLearning #FutureEngineers #K12Education #STEMForAll #SportsAndScience #LearningThroughPlay #WeAreDallas #WeAre26 #FWC26Dallas

Universes. Cosmology. Curvature. Einstein and Beyond. Here is a page from the seemingly infinite notebook of Yuri Kovalenok, @jurijkovalenok1 -- a physics teacher who, through the years, jotted down his many thoughts and sketches for us to ponder. Artwork used with permission.

Problem of the Week 171! Please do not comment the solution so others can work it out too. Instead, like this post or comment a thumbs up if you think you have the correct answer! The solution will be posted in the comments on Thursday afternoon. #Problem #UKMT #Maths

🧠 Can you solve this riddle before the answer appears? 👀

It's Mental Math Monday! How would you mentally calculate how much it costs me to do laundry when I do two loads at a time and a washer costs $2.75 and a dryer costs $2.50?

This 2-day lesson for grades 3–5 helps students discover #geometry vocabulary through exploration. Students sort shapes, find parallel sides, spot right angles, and then apply it all with #tangrams to build quadrilaterals that meet specific criteria: nctm.link/PN0X4

N! counts the number of ways to arrange the numbers 1, 2, ..., N in a list. (It's conventional to set 0! = 1.) We have the sequence 1, 1, 2, 6, 24, 120, 720, ... Take the differences of this sequence: 0, 1, 4, 18, 96, 600, ... What do these numbers count?
