I can multiply a binomial times binomial and get a binomial.

Or a binomial times a trinomial to result in a binomial.

Is it always possible to multiply polynomials with any # of terms and end up with a binomial?

(m terms) x (n terms) = 2 terms?

Does m or n have to be even?

order of operations:

parentheses ()
powers ^
product ×
partitive ÷
plus +
pluck -

Learning all about #slowrevealgraphs tonight with Jenna Laib at the Chesnut Hill School! 📈

looking for YET MORE materials on trig and inverse trig? here are some that i just wrote up (screenshots below):
docs.google.com/document/d/1Pg…

[ #MTBoS !]

the #3 problems are all intended as challenges; see e.g. the following graph for an interesting(?) example:
desmos.com/calculator/opd…

here is a convenient (?) collection of domain, range in degrees, radians for trig and inverse trig functions [as compiled by grade 10 students!]

do you have materials on [intro to!] inverse trig and/or radians? are they GOOD materials? let me know!

cc. #iTeachMath et al

in alg 2 w trig we did trig (degrees), polynomials, exponentials; then looped back w inverses in reverse order: logarithms, radical functions, and now inverse trig (using degrees *and* introing radians!)

in case it's of use? trig & inv trig domain & range

the goings on at Columbia and other U.S. campuses (or at least, their flat representation to those afar, like me)
does not seem
directly connected to
the goings on in the middle east (layered, nuanced, & horrible to those who are here, like me)

Music is so math-y! (And vice-versa!) 7th graders and I used our knowledge of fraction operations to translate sheet music to fraction bars on polypad. Mathigon Amplify

Beyond excited about Rachel Lambert’s desperately needed new book! I cannot wait to dig in with so many people in my district. (Especially the IEP goal-writing chapter!!! LFG!!!) Rachel Lambert (look for me on sky now)

Congratulations to Angela Liu, Kristie Sue, Jessica Wan, and Hannah Fox for bringing home the gold! The USA Team earned first place in the 13th European Girls’ Mathematical Olympiad (EGMO), and each student also earned a gold medal for their individual performances. #TeamUSA 🥳

Just got word, 'Who's who: How “women of color” are (or are not) represented in STEM education research' is one of the top 10 most-cited papers published in Science Ed #TopCitedArticle 🥂Cheers 🥂 to us Monica Miles Terrell Morton, PhD

Last week Matt Parker had me join one of his 'Evening of Unnecessary Detail' events in New York. I invited 🎵 Tim Blais 👨🏻‍🔬 to come down and we had a bit too much fun writing a parody of 'Ain't No Sunshine' about the twin prime conjecture.
