🧊 The Impossible Cube: A Mind-Bending Illusion! 🧊 By carefully arranging lines and angles, this cube tricks our brains into seeing a three-dimensional object that could never exist in the real world. 🌀 #mathkangaroo #mathisfun #ImpossibleCube #ArtAndIllusion #BrainTeaser

The following formula yields the correct decimal digits of π to 42 billion digits

We have several 2nd graders who take amazing notes - of their own volition and without being asked. What great habits they have self-inculcated that will serve them so well! #mtbos

It’s first quarter test day for level 5 and prealgebra students. We hope it’s a challenging yet fun learning experience and helps to show the students how much they have learned. #mtbos #mathTest

2¹³⁶²⁷⁹⁸⁴¹−1, discovered today, is the largest known prime. It's a Mersenne prime (2ᵖ-1), which are easier to find. It took nearly 6 years for the GIMPS software to find it after the previous largest known prime. It was also the first Mersenne prime found using GPUs.

We have Level 2 (2nd & 3rd graders) Ss enact on an imaginary number line finding the ‘middle’ number btwn two numbers. They take the same number of steps toward each other, efficiently or less so, no matter, till they meet. (pick two whole nums of same parity) #mtbos #mathisfun

#bugFest @NaturalSciences is going well- we’re enjoying sharing #mathisfun with thd attendees! #mtbos

We had a lot of #mathisfun in our 2nd/3rd grade class including a cool way to find the middle number of two numbers, which we enacted. #mtbos

Join us at BugFest at @NaturalSciences Saturday 10-7 where we are part of the ‘Math Neighborhood’ with math activities & ideas related to insects. We’re honored @NaturalSciences invited us to this big annual event! https://t.co/zJtMqdGtPU @MathHappensOrg @NaturalMath #bugFest

Our level 3 & algebra classes started yesterday with a lot of #mathisfun. After distributing texts, binders, colored / mechanical (triangular) / regular pencils, & t-shirts, we looked at angles & triangles & played a game in level 3, and explored arith opers in algebra. #mtbos

T-shirts and organized binders ready to go - we also have #vegan cake for our first big day of classes! #mtbos

Today are our first big classes! Geometry is already underway; in this classroom we are ready with supplies including tshirts and organized binders! #mtbos https://t.co/TUHOWaimIN

We’re ready for our level 2 class with supplies, lesson, and a game - plus a tasty #organic Mallika mango from @WeaverStreet for each child!

Today our classes start! We’re picking up tshirts for each student. #mtbos

Classes at https://t.co/TUHOWaimIN start on Friday! For our upper level classes we recommend students make their own references of their most difficult problems, solving clearly and neatly. We’re trying nice binder inserts for them - just picked up @FedEx & they look good! #mtbos

Books and books and supplies and more all still arriving with much more to come - we’re excited that our new school year at https://t.co/TUHOWaiUyl is starting in a bit over a week including a kickoff dinner party next Friday! #mtbos
