October 22, 2021: Things Teenagers Say Volume 60
It has been a VERY crazy week, so I thought I would end the week with a new volume of Things Teenagers Say. This is my regular round-up of the crazy and memorable things I hear my students say in class.

One week into school…
Student: Wait. We have lockers?
—
They put letters in math problems. Why not put math problems in letters?
—
If you give me detention, I will catch my tears in a cup and pour them on your head and it will make your hair look weird.

—
Student A: Would you be a dear and let me copy your notes?
Student B: I’ll be a deer. A deer in the headlights.
January 3, 2022: Monday Must Reads: Volume 95
It’s the first Monday of the new semester for me, and I have to be honest that I wasn’t thrilled to set my alarm last night for a day full of professional development meetings today. I know that I’ll get my teaching energy and enthusiasm back tomorrow, though, when I find myself in a room full of teenagers again.
To help get in back-to-school mode, here’s a new volume of Monday Must Reads. This is my weekly-ish attempt at capturing the creative ideas shared by other (mostly) math teaches on twitter. I hope you find at least one or two ideas that you can adapt for your own classroom.
Word Wall and Words of the Week Display
Vocabulary is definitely an area of teaching where I could improve. I really like this idea from Austin Coleman of posting weekly vocabulary that you want to focus on.
Desmos Gingerbread Houses
Tricia Krumbach inspires with an idea I’m filing away for next Christmas – Desmos Gingerbread Houses!
Mathematical Memes with Template
Scottie O’Neill suggests having students create their own mathematical memes using a template. I love this idea!

Katie Marhefki suggests using the Two Truths and a Lie practice structure with polynomial theorems. Brilliant!
Using Mentimeter on the First Day of School
Check out these examples from Kristen Fouss about how to use Mentimeter in the classroom.
Panda Square Parades
I realize this is an old tweet, but I only ran across it recently. I love this twist on Panda Squares from David Butler – a Panda Squares Parade.
8 5 4 9 1 7 6 3 2 0 Sequence
Justin Aion shares a clever brainteaser.
Math Puzzle Bulletin Boards
Leah TenEyck highlights a brilliant way to display puzzles to capture student interest.

Check out this fun probability lesson from Kim Jackson!
Until next week, keep sharing your great ideas! You may just find yourself in a future volume of Monday Must Reads!
March 7, 2022: Monday Must Reads: Volume 96
Today feels monumental for some reason. It’s the last Monday before Spring Break. The rest of the school year always seems to fly by after Spring Break, so it almost feels like this is the point in the school year where I’ve “made it.” I’ve survived another year of teaching.
The end of this school year will mark a decade of classroom teaching. Since I started blogging while student teaching, that means I’ve been writing about teaching math for over a decade. How is that even possible?
One of the best things I’ve done over my teaching career is to seek out ideas from other math(s) teachers around the world. I hope you’ll read on and check out my newest volume of Monday Must Reads – my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter!
Graphing Food Decay Activity
Check out this memorable lesson from Mr. Collier which involves decaying food and Desmos! Students select item & monitor it for 2 weeks. Students weigh item each day (using a scale that is accurate to two decimal places) then use that data to write their function to predict the next day’s weight. Items are covered with wrap during the process. Very interesting!
Fractions and Decimals Open Middle Task
Will M Dunn shares a lovely open middle style problem involving fractions and decimals.
Inspiring Desmos Skirt
I am blown away by this Desmos skirt that was hand-crafted by one of Nat Banting‘s students. Wow. Just wow.
Notice and Wonder Hallway Display
Ashley Skiffington showcases a great way to incorporate Noticing/Wondering into your school culture!
Interactive Math Wordle Display
If you are obsessed with Wordle, check out this interactive Math Wordle Display from Molly Owles.

Peardeck Weekly Themes
Looking to infuse a bit of fun into your class? Sevdije Perezic does this by letting students pick a weekly theme.
Pi Day Facts
Tracy Darbyshire uses Pi Day as an opportunity to share fun math facts with her students.
Graphing Window Hack
Nicole Miller shares a clever teaching hack for anyone with a plethora of windows in their classroom. Tape graph paper on the outside of the windows to make it easy for students to create graphs on the glass with dry erase markers.
Until next week, keep sharing your awesome teaching ideas!
March 21, 2022: Monday Must Reads: Volume 97
It’s been a rainy Monday full of prepping to attend an ACT training tomorrow and analyzing our spring ACT benchmark data as a math department. I thought I should take a bit of time today to put together a new volume of Monday Must Reads.
Can you believe I’m getting close to reaching 100 volumes of Monday Must Reads? Monday Must Reads is my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter. I enjoy sharing and amplifying these ideas so they can impact as many classrooms as possible.
Quadratic Equation Puzzles
I’m super excited that Nicole Whitty has started a new math teaching blog with some amazing free resources! I miss the days when it seemed like everyone was sharing free resources on their math blogs, so it’s super exciting to see a new blog pop up.

March 29, 2022: Things Teenagers Say Volume 61
It’s been way too long since I put together the last volume of Things Teenagers Say, so I thought I would remedy that issue. This is my regular round-up of the crazy and memorable things I hear my students say in class.

April 11, 2022: Monday Must Reads: Volume 98
I can count on one hand the number of Mondays that I have taught since the pandemic began in 2020. When we returned to in-person instruction in the fall of 2020, we adopted a calendar of Distance Learning Mondays where students would complete their lessons asynchronously each Monday.
The high school I teach at kept those asynchronous Mondays this year as well. But this week, we ended up having to move our distance learning day to Wednesday instead of Monday due to ACT testing. This meant that I had a room full of students on a Monday!
To celebrate surviving a Monday with students, here’s a new volume of Monday Must Reads. This is my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter. I hope you find an idea or two worth adapting for your own classroom!
I am now only two volumes away from 100! Anyone have any ideas on how to celebrate this upcoming special volume number?
Triangle Midsegment Activity
David Sladkey shares a fun, hands-on geometry activity with lots of student choice!
Calculus Class Playlists for Remembering +C
Julie Reulbach shares some creative Spotify playlists she put together for remembering the +c when integrating and for u-substitution.
Transformations and Reflections Playlists
These transformations playlists from Ashley Spotted Wolf look super-engaging!
Calculator and Slide Rule Display
Check out this calculator and slide rule display from Mark Kaercher. Very inspiring!
Pythagorean Theorem, Distance Formula, and Midpoint Formula Mystery Activity
I am super impressed by this crime solving mystery activity put together by Sevdije Perezic.
Isosceles Triangle Puzzle
Catriona Agg shares an isosceles triangle puzzle.
Volume of Solids Geometry Project
Jennifer White shares an engaging performance task she gave her geometry students.
Math Flips Flash Cards
Berkeley Everett has an excellent free resource on his website called Math Flips. These flashcards are not your normal flashcards. Instead of having a problem on one side and the answer on the other, these cards have a problem on the front and a similar problem on the back to “encourage relational thinking instead of answer-getting.”
Math Word Walls
Nicole Whitty has written another excellent blog post which shares several inspiring math word walls worth checking out!
Quadrilaterals Conjecture
Tracy Proffitt shares an interesting mathematical conjecture shared by a student. How would your students respond?
Until next week, keep sharing your awesome math teaching ideas!
