This little superhero? That’s MJ—my son, my inspiration, and clearly someone who never hesitated to take a leap.

Tomorrow, I’m rappelling 22 stories in his honor for Rappel Boston 2025—and thanks to your donations, I won’t be doing it alone. 💜

@kurteichenwald - I heard you speak at the EFNE event last night. Thank you for your passion and everything else you do to bring epilepsy out of the shadows!!!

[Marc Firenze @marcjfirenze]

@Natolino_ @JlYEON L'Hopital's Rule can also get you there.

@AllRealMath @normabgordon Thank you - I've an AP Calculus student who, and I quote, "doesn't do fractions"

[Marc Firenze @marcjfirenze]

A student just shared this with me and told me "I saw this and I understood it thanks to what we learned in class : )" Very proud and glad to have some great material for the next time I teach it - wishing I could properly acknowledge original author #LUmathmethods

[Marc Firenze @marcjfirenze]

I've been thoroughly enjoying Journey Through Genius to learn more about the math history - what a story!!! #LUMathMethods @normabgordon

Proudly ran a demo Desmos class in my department meeting today - lots of oohs and ahhs. @desmos @normabgordon #LUMathMethods

Any PBL ideas or resources for a unit on conic sections? #LUmathmethods, @normabgordon #iteachmath, #MTBoS

@MichaelisMath If one costs $10, then retail price for 4 is $40. When you get 4 for $10, then my math tells me it is a 75% discount at best (because of equal or lesser value clause). Amount of Reduction/Original Price is 30/40 = 75% Am I missing something? #LUmathmethods, @normabgordon

@AllRealMath @normabgordon I made my first major assessment take home with a mirrored review beforehand because of this phenomenon. In the post assessment survey, received 100% confirmation from students that it was fair. Considering in class group testing as a next step. #LUmathmethods #iteachmath

@MrWagsMath Thanks for sharing the technique and this specific problem - going to borrow it and share with my cohort of educators #LUMathMethods at Lesley.

[Marc Firenze @marcjfirenze]

Used the Land the Plane Demos activity on Linear equations as a way to remind students of all the background knowledge they had. The reviews were exceedingly positive and engagement was really high - thanks @Desmos for a fabulous tool #LUMathMethods #iteachmath

@dgstonge Please pass my appreciation to Abby for jumping in. As the dialog suggests, it is interesting to find math problems where more than one reasonable answer exists.

[Marc Firenze @marcjfirenze]

Curious - how would you interpret the result of this inequality: 10 < x < 5
A: The union of real numbers that are greater than 10 and less than 5
B: The intersection of real numbers that are greater than 10 and less than 5 which results in the NULL set #iteachmath #LUmathmethods

@MsPruittTeaches Thanks for sharing - keep your bar where it is. I'm trying to make the distinction between two different bars - mathematical competency and responsible behavior. I'll move the skill bar faster and farther - but I don't lower the behavior bar much at all.

@MrsMankaMath Learning mathematics is not just about getting the right answer, it is about "communicating" or "mathematical discourse". As a result, showing your work is the means of facilitating this dialog.

@pgliljedahl - I gave the Two Bike Problem to one of my students today (care of my professor @normabgordon). I created a brute force method of solving/calculating with a spreadsheet, are there other more elegant approaches out there? @lumathmethods #iteachmath #hsmathchat

I'm teaching limits and would appreciate any ideas for how to explain the concepts of "infinitesimally small" and/or "approaching but not equal to" #hsmathchat #iteachmath
