Teaching Reflections: Year 10 (2021-2022)

September 13, 2021: Monday Must Reads: Volume 89

Now that I’ve been back to school for about a month, I finally feel like I’m getting in the swing of things. My school is doing distance learning on Mondays this year. However, students are allowed to still come in person on Mondays for extra help or if they need to make up missing work/tests. I gave my first Pre-Calculus test of the year on Friday, so I had a million students in my room today. I survived, though. I even got to help a former student with some calculus which was fun.

Since it’s Monday, I decided that it was time to put together a new volume of Monday Must Reads. MMR is my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter. I hope you find at least one idea you can use in your own math classroom. There are even a few science ideas this week for the chemistry teachers who might be reading this.

Introducing the Distributive Property

Amie shares a great series of problems that can be used to introduce the distributive property. I really like how students have to determine if they can apply the distributive property or not with each problem.

3D Bohr Models

This 3-D Bohr Model display from Reagan Josephison caught my eye recently when scrolling through twitter. It’s creative activities like this that make me miss teaching chemistry!

Justifying Function or Not a Function Worksheet

I really like this function worksheet that Jessica Merrill recently highlighted. I appreciate both the fact that it requires students to write sentences to justify whether the relation is a function AND it teaches students how to write these sentences.

Using Geometric Transformations to Solve Puzzles

Sarah Furman shares an absolutely brilliant activity where she combines student knowledge of geometric transformations with puzzle creation. Students had to create their own puzzles similar to Cover the Duck, Cover the Heart, Cover the Camel, etc. Then, they had to use geometric transformations to describe the solution to the puzzle they created. I am just blown away by this activity.

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. 

Things Teenagers Say

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.

If my ovaries don’t stop me from having children, my wish for fame will.

I got rich people chocolate milk.

That’s the only reason I go on all these college tours. Free T-Shirts.

Student: Are we allowed to work with partners?
Me: Sure.
Student: No thank you!

Is it Adam’s rib or Eve’s Rib? I don’t know. Oh wait…it’s Adam’s apple!

Student A: You’re a cosine.
Student B: That’s not nice!

I know why the bell at the end of the day hasn’t been ringing. Somebody stole the bell!

Is the homecoming game a home game or an away game?

Student A: Why is there half a ruler in my backpack?
Student B: Maybe you got a little hungry?

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.

October 25, 2021: Monday Must Reads: Volume 92

Happy Monday! Welcome to another volume of Monday Must Reads, my weekly-ish attempt at capturing the amazing ideas shared by (mostly) math teachers on twitter. I hope you find an idea or two to use in your own classroom or to share with a coworker. This week’s volume features not only inspiring math teaching ideas but ideas from physics, chemistry, and Spanish. I am a firm believer that learning from teachers of other subjects improves our teaching.

How it Started…How it’s Going

I am a big fan of this “How It Started…How It’s Going” structure to get students to realize how far they have come in their learning throughout the year. This example is from Amy Lenord, a Spanish teacher, but I would love to see math teachers adapt the idea for their own classrooms!

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.

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!

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.

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. 

Things Teenagers Say

Me: Hyperbola is such a fun word to say. Hyperbola, hyperbola, hyperbola.
Student: I like saying asymptote. I feel like I’m getting away with something.

Student 1: You are so funny. Where did you get your sense of humor from?
Student 2: Junie B Jones.

Watch out. This one is a negative slope. It’s going downhill like my life.

My phone is more modern than your stone age phone.

Can you get in trouble for skipping a class if it’s a sports class? We’re running and I don’t want to.

I am not taking cough medicine. I am NOT letting my dad win that battle.

I feel sooo tall today.

My life isn’t sad. I just hate Valentine’s Day.

Party in my backyard. We’re burying my computer.

Student 1: How am I done before you?
Student 2: Because I was looking at memes.

You’re literally built like a block of cream cheese.

What did you do today? Go to school? Me too.

You wore sweatpants to a job interview?

Student 1: What was that sound on the roof?
Student 2: Thanos.
Me: It wasn’t Thanos. It was Santa.
Student 3: I don’t believe in Santa, but I believe in Thanos.

Student 1: Wait. Do you have a purse inside of a purse?
Student 2: No, this is my wallet!
Student 3: Are you just now beginning to understand women?

That joke died like two days ago.

This is supposed to be cosine. What in the ravioli is this?

I can’t write on this paper. It has to be straight from the tree.

One student to another: You look like a mom who just got back from yoga. That’s a compliment, too.

Why are you so against croutons?

I only eat Bueno for the salsa.

I’m not taking a gap year. I’m taking a gap life.

I never knew you had a stepmom. When did you have her?

I paid for that whole speedometer. I’m going to use that whole speedometer.

Do you have hair on your toes?

Student 1: You go to Planet Fitness? I go to Planet Fitness!
Student 2: I’ve been going there for five days and I haven’t seen you. Are you sure?

It’s been over 24 hours since I last had a Belgian waffle.

Student 1: Can I say that you are terrible at flirting?
Student 2: That was just me saying hi.

Student 1: People that unfriend other people are fake friends.
Student 2: But I resubmitted my friend request in person.

It’s okay. Starburst wrappers are edible.

Do fish get thirsty?

Student who came in my room during lunch: Are you listening to an audiobook sped up? That makes you a terrible human.

I would have so many college offers if my twitter wasn’t private.

Student: Is the test timed?
Me: Yes. 5 minutes.
Student: 5 minutes?!? That’s going to be the fastest F I’ve ever made.

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?

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.”
