Thank you to all the amazing math educators, coaches and professors that attended my first solo NCTM session: Humanizing Mathematics through Cultivating Joy! #nctm #nctmchicago #nctmchi24 #mtbos #iteachmath

Awesome proof without words! Relationship between Quadratic mean, Arithmetic mean, Geometric mean, Harmonic mean and '-2' mean ...

Important points to remember in probability.

Start your day with this #yohaku. Fill in cells with 9 different factors of 90 to get totals shown in each row/column.

Important points to remember in Arithmetic series and Geometric series.

How to build a good understanding of math for machine learning? I get this question a lot, so I made a complete roadmap for you. Three fields make this up: • Calculus • Linear algebra • Probability theory Let's take a quick look at them:

A Mathematician’s Clock

Love both Brian and Debbie’s strategies, but most of all love Debbie’s reflection. That reflective practice is so important in math-ing behavior and teaching! #MathIsFigureOutAble #MathStratChat #MTBoS #ITeachMath #MathEd

Sharing this again to address misconception about square roots. From Dr. Garces #sharingisthenewlearning

"Probability is the logic of science." There is a deep truth behind this conventional wisdom: probability is the mathematical extension of logic, augmenting our reasoning toolkit with the concept of uncertainty. In-depth exploration of probabilistic thinking incoming:
