In #MathsToday we noticed how the shadows of the minfigs were changing with distance from the light source and modeled it with a rational function.

This lab is so much easier now with cellphone lights than lightbulbs we stole from science back in the day. #Algebra2
In the foreground is a student desk with meter stick a Steve the Minecraft mini fog casting a shadow onto a mini whiteboard. Next to the shadow is a ruler a student is using to measure the height of the shadow. Background is dark as the lights are dimmed.

Doesn’t have to be common:

9/8 div by 3/2 is 9div3 over 8div2

3/4

My algebra2 kids were blown away by not having to multiply by the reciprocal and needing a full rewrite of the algebraic fraction, factored properly.

The first session of the quarter at HMA is over. I think I have about 25 kids spread across the A and B blocks which is a great ratio. I'm doing some algebra2 material in one and number theory in the other. My particular goal with class assignments was to repeat the material I used last year so […]

It’s my favorite time of year. Polynomial time in #MathToday Starting off with the painted cube problem.
#Algebra2
Student whiteboard work showing a cube net with coloring annotation. Also a table recording the number of cubelets with 3,2,1, and 0 faces painted for various dimensions of cubes. Students constructing a cube frame out of snap cubes.

Working on multiplying matrices in #MathsToday

#Algebra2 #iTeachMath
A whiteboard showing student work on multiplying matrices. You can see the arm of a student holding a whiteboard marker pointing to something in the work as they discuss. The whiteboard work includes multiplying a 2x2 matrix by a 2x4, writing the matrix dimensions checking to see if they can be multiplied, and multiplying a 3x1 matrix by a 1x3 matrix.

Yesterday was our first day of school. In #Alg2 #Algebra2, I put the kids into groups of 3 and asked, if we all shook hands with everyone in the room, how many handshakes would that be?

I LOVE this problem, esp. on Day 1.

Got my ropes ready for a system of equations task next week. Now I can enjoy my long weekend. #iTeachMath #MTBoS. #Algebra2
There are roughly 40 lengths of cord with their ends melted. Half are 1/4 inch thick and fluorescent yellow. The other half are 3/16 inch thick and colored white with grey stripe. In the photo is the lighter which melted the ends to keep them from fraying.

lol, two guys gave me an ACTUAL WEDGIE in class in freshman Algebra2, in front of the class. And that was just one instance of dumb bullying.

And yet, I’m not a colossal piece of shit.

Some people are born horrible humans, and it is what it is.

I know it's popular to say if Stephen Miller got laid and/or wasn't picked on in school he wouldn't be like he is. As someone who didn't get laid and got picked on in school I'm pretty sure there is something more deeply wrong with him than tough school days.

When doing a probability test for independence, what is the tolerance for equality? In other words, because we're using integer values P(A) may not be exactly P(A|B), but how different can they be before we suspect dependent events? #MTBoS #iTeachMath #Algebra2

Swiss Thrash Metal Force Algebra Unleash Explosive New Live Album Live at RKC May 30th - @thebeast
FOR IMMEDIATE RELEASE Swiss Thrash Metal Force Algebra Unleash Explosive New Live Album Live at RKC May 30th Presave and stream: https://distrokid.com/hyperfollow/algebra2/live-at-rkc Swiss-based thrash metal wrecking crew Algebra are set to release their crushing new live album Live at RKC on May 30th, 2026 via Metalworld Records on digisleeve CD and Oss Da Mord Records on cassette, alongside a worldwide digital release across all streaming platforms. Captured at The Rocking Chair (RKC) in Vevey, Switzerland on January 20th, 2024, Live at RKC documents the final performance of the band’s acclaimed Chiroptera cycle. The album delivers a fierce and uncompromising set featuring the majority of the Chiroptera material alongside selections from the band’s back catalogue. Raw, aggressive, and completely unfiltered, the recording showcases the band in their natural habitat: loud stages, blinding lights, and total chaos. Fans of Sepultura, Slayer, Death, Biohazard, Power Trip, Exodus, Pantera, and Forbidden will find plenty to sink their teeth into as Algebra continue to sharpen their blend of razor-wire thrash riffs, punishing grooves, and relentless energy. The band states: “‘Live at RKC’ captures the final show of our Chiroptera cycle. It’s a raw and unfiltered document of that night. This release marks an important milestone for us, and we’re proud to present it in both audio and full video form on May 30th, 2026. Special thanks to Jon, our bassist, whose precision and dedication shaped the entire video production — his work is an integral part of this release. Turn it up and experience it as it was meant to be heard: loud, intense, and alive.” Production credits for Live at RKC include FOH and recording by Jan Saunier, mixing and mastering by Raphaël Bovey at MyRoom Studio, cover art design by Mike Cotton-Russell based on an original artwork by Adam Burke, videography by Jonas Lacôte, video editing by Jon Emery, lighting engineering by Sébastien Baudin, and photography by Alain Jordan and Julien Waroux.

Every year, #Algebra2 Ss learn to determine if a relation is a function.
Function sends every input to exactly 1 output, but that output doesn't have to be unique.
^^ can be confusing.
Tried new analogy today, working w/student who is a rower on the crew team.
