I am a teacher

I am a teacher. I decided to become one in 3rd grade and never changed my mind.

I am a teacher. It’s all I’ve done for work after college.

I am a teacher. This year has taken a lot out of me. Week after week. I stumble through my toughest year in this job. Wondering if I can do this another week. But I do. I don’t know what else to do. For me. For my family. For my students. For my school.

I am a teacher. I wonder what if? What if I left? What if I did something else? What if I stayed? What if I stayed and I’ve lost my fire for this job? What if I can’t relight the fire?

I am a teacher. I worry so much about the impact all of these impossible choices and situations that are beyond our control are having on our young people. My students. My daughters. I worry about my girls. I worry about my colleagues. I worry about our county. I worry about the world.

I am a teacher. Can you turn your video on? Can you answer in the chat? Can you reformat that file because our LMS will not read it? Can you come to office hours for help? Can you hear me? Or am I on mute?

I am a teacher. Of course you can use the restroom. Yes, please come to office hours for help. Thank you for the kind email. I love the jokes you put in the chat. It is so good to see you in Zoom today.

I am a teacher. And I will be one next year too. Because I don’t know what other job so closely aligns with my strengths or my passion. So this year has me seriously doubting my resolve to do this job. And I have a strong suspicion next year might too. But I will stay for another year.

Because I am a teacher.

A Challenge I Faced In 2020

Have you ever been on a zoom call and when the person shares their screen, you can see they have 20 tabs open? Or someone shares a screen shot and you can see they have 12,476 unread messages? And then it becomes a discussion point. And it quickly highlights the very different type of people there are in the world and how they organize their work life.

Well, since March, I’ve felt like I’m functioning with 20 tabs open in my head at all times. I’m terrified that one will close and I will lose the information or I won’t be able to find the information I need.

I also feel like I have an inbox in my head with 12,476 messages. Some very important, some with invitations to things I want to do, some with advertisements.

This has been an overwhelming year. My Wi-Fi signal is weak and I need to organize my tabs and inbox. I don’t have enough bandwidth to add any more apps or programs to my life.

So I apologize if yours was the zoom call I missed. Or yours was the 5 book reads I signed up to do and I just couldn’t get to it. I’m doing my best this year, and my best right now is to just get by.

Stay Positive (Year 18)

Stay Positive

Next week, both my IM1 and IM3 classes will explore functions. Today, the first day of school in the virtual setting, I think about this function (seen on my mask), absolute value, that is the distance a number is from zero. So no matter the input, the output represents distance and is a positive value. Well, unless the input is zero.

Absolute Value Function

And yet, this year feels like we’ve reflected this function over the x-axis. No matter what we put in, the outcome is negative.

What 2020 Feels Like

I’m tired of complaining. I’m tired of all the bad news. I’m tired of things going wrong. I know all the bad things are still going to happen. As I think about my day, and scroll through my pictures, I noticed the mask I was wearing today. I bought it the second I saw it in my FB ads. (Don’t judge. They know me too well.) . This mask with the absolute value function on it. I have a shirt with this too. it made me start thinking about all the things that happened today.

What was positive today?

1. I had 100% of my students present in my classes today. I was not expecting that.

2. Zoom first period was a disaster. And it wasn’t the students. It was me. But I got better each period, and by 7th period I felt confident navigating Zoom.

3. My classroom feels lonely without my students, but it was good to see all their faces in the zooms.

4. Student submissions of assignments in Canvas happened immediately after 7th period. So many for me to read through and grade.

5. The students are being really honest in the information Google form. They miss their friends and learning in person. Some are afraid of math. But so many expressed excitement for a new school year and hope. They give me hope.

6. My 4th grade daughter came out of her first day of zooms and said “that went fast!” She seems excited about the school year.

7. This challenge has brought our math department together in a way that is amazing. So much encouragement and support between colleagues. I’m proud of the work we’ve done to prepare for the school year.

8. Our admin team should take so much credit for the fact that our students were all logged into the zooms today with very little absences. So much planning and training and passing out of materials and Canvas support. I’ve been overwhelmed by the scale of what I have to do, but their tireless work set us up to succeed as much as possible today.

Today’s first day of school picture was brought to you by the absolute value function, here to remind you to stay positive. In a year that feels like everything has gone wrong, I’m going to try to focus on the positive things that happened today.

Power in Numbers- #NCTMSD2019

I often tell my students that collectively we are smarter than we are by ourselves. I really felt this when I was at the NCTM Conference in San Diego, in April 2019.

I started this blog post after returning from the conference and never finished it. It’s now been over a year since I attended this conference, and I’d like to share how it’s impacted me since. And how this idea of Power in Numbers is also going to be important during the 20-21 school year.

Attending the NCTM Conference has been on my bucket list of things I’d like to do since I first started teaching. However, it’s rarely near me, and I’m a fearful flyer, and it’s expensive, for many years our school would only cover so much for us to attend CMC in Palm Springs, and well, I’m an hour away from the CMCSOUTH Conference in Palm Springs. CMCSOUTH is an amazing math conference and every year its an hour away. I can attend without booking a hotel room, although the only year I’ve done that was after maternity leave.

So when we saw that NCTM was coming to San Diego, we started pestering our admin and even applied to speak. My session, A Journey from Rows to Groups, was accepted and as a secondary TOSA, my district helped cover the cost of the hotel and food and registration.

Attending NCTM was an amazing experience.

Here’s a link for the top retweets using the conference hashtag, #NCTMSD2019, compiled by Dan Meyer.


My colleague, Patricia Vandenberg, who was also going as a speaker, and I were so excited to attend and experience everything. We even registered for sunrise yoga on the first day.

My husband. “You are not a morning person and you don’t work out.”

Me. “You’ve obviously never met math conference Claire. And they give you a yoga mat that says I love math!”

Every session I attended was energizing. The conversations I was apart of and those I overheard between sessions as people were rushing to the next session or lingering in the exhibit hall were full of purpose and ideas and life.

One thing that struck me was the scale of everything. The San Diego Convention Center is huge. And there were math educators from all over the world. And through social media, there were thousands of teachers all over the world who were not at the conference who got to be apart of the conversation, too.

And then, Dr Talithia Williams, a statistician at Harvey Mudd, and author of “Power in Numbers: the Rebel Women of Mathematics” presented a powerful closing address.

I left that conference with an overwhelming feeling that we, the community of math educators, have a power in Numbers.

It’s been over a year since that conference. As a group, we face a challenge that seems impossible this school year. How do we care for our students in the midst of a worldwide pandemic? How do we keep them safe? How do we protect their right to an education? A right we often take for granted in our first world nation. How do we pass on the beauty and joy and wonder within mathematics to the next generation? And do it over zoom? How do we help heal the pain and fear many of our students face over health and jobs and politics and unrest that’s all over the news?

I think the answer is that we work together. We are a community of teachers and there’s power in our numbers.

Have a question? Please ask! Have an idea, share it! Someone sharing a difficulty, let’s listen and learn. Need a place to start in the conversation? Search the hashtags and then include them to help engage in the conversation.

I don’t know all the #MTBoS and #iteachmath hashtags, so please share below to help any newcomers. We are all going to need each other to get through the year.


[I drafted this March 10, before COVID-19. Cleaning out my drafts for #MTBoSBlaugust. ]

Last month, I was fortunate to attend the CPM Conference in San Francisco, CA. This Conference is for teachers who use the CPM Curriculum, which is designed for student collaboration. Each session I attended, the tables were set so that attendees could have conversations. Just like our classrooms. Even if the session was delivered primarily as a “speech”, the speakers used many of the cooperative strategies we use in our classes to get our students talking to each other.

I am fortunate and attend with many people that I know, but this conference makes it super easy for adults to make new professional friends. People that you see passing to the next session and feel comfortable saying “hi!” (I’m an introvert, so this means something to me.)

One of the first things I ask someone at a Conference I attend is, “are you on Twitter?” To someone who is not on Twitter, this question probably sounds weird. Maybe creepy. I’m not trying to be creepy.

You see, I often get weird looks and then statements like “I’m not on social media.” Then I find myself trying to explain what Twitter means to me professionally. And a month ago, I know I wasn’t explaining myself very well. But, I’ve realized in the few weeks since the CPM Conference #WhyTwitter.

You know all the conversations I mentioned at the beginning of this post? The ones I had in my conference sessions? When both of us are on Twitter, we get to extend our conversation past the session.

Since I started following math teachers using the #MTBoS hashtag on Twitter, I’ve extended my professional learning network past the borders of my school and district. This has been a place that I’ve come to in the past 5 years to grow and learn and push myself. It’s also like attending a professional conference anytime I want and have all the conversations I want.

I am a better teacher because I’m on Twitter. And now when I attend a conference, I have people to save me a seat at a session.

What are your reasons?


Translations, rotations, and reflections, used to appear as maybe one question on the California Star Test back when we taught under NCLB. Most years, I didn’t teach it. I really didn’t understand it’s value in the curriculum.

After we switched to Common Core and our school adopted the Integrated Pathway, Transformations were the area I had the most to learn about. See


It’s so funny how the more you teach a topic, the more connections you make to different topics. I taught Pre Calculus for 10 years and absolutely loved teaching students the Unit Circle. Each year, I’d find a new pattern I’d never noticed before.

My last year teaching Pre Calculus, 4 years ago, I showed my classes a bunch of sine curves and had them make a list of everything they noticed about eacH graph. I also had them predict the equation of the curve.

What do you notice? What is the equation?

Y=sin(x) they figured out but when I revealed y=sin(x/2) they gasped. They had predicted y=sin(2X). So when they started talking about what happened to the period they described the period change as 2pi/b. All by themselves.

Can you figure out why they predicted y=sin(2X)?

I had to give up Pre calculus to be a part time math coach for the past 4 years, so this past week is my first time introducing students to the unit circle since then. This is my first group of students to learn the Unit Circle who learned about transformations in Integrated 1.

Can I say that I now see the importance of learning about Translations, Rotations, and Reflections?

My students found the coordinates of points on the unit circle given an acute angle. Then, without any direction from me, just by reading a question in their CPM textbook, reflected the triangle over the x and y axis to find the points in the other three quadrants AND their angles from 0 degrees.

The textbook has them plot the points of the height of those triangles based on specific angles to initially discover the sine function and make observations about the points on the graph. Some students observed to find the other points on the sine curve with the same and opposite values, you reflect over the y-axis and translate it. And others observed the points on the sine curve were a 180 degree rotation about the point (180,0).

I’m 17 years in this profession and I’m still learning how everything is connected. My reflection is that we might not fully understand the impact of the mathematics we teach, but the significance is there and it may not appear for a few more years.

(Also, my reflection is that reflections are important. )

Fur Babies

[I initially write this February 17, 2020. Cleaning out my drafts for #MTBoSBlaugust.]

I grew up with cats. I love their independent nature. I love that they don’t necessarily like everyone they meet. I’m secretly jealous that they get to lie around all day and no one expects different from them. I love how affectionate they can be, when they want to or if you’ve opened a can of tuna.

Tuxedo cat came home my freshman year of high school and he got us all through high school. We’d come home from school stressed in a way that teenagers are stressed, pick him up, and instantaneously felt better. I couldn’t wait to get my own cats when I “grew up”.

The day we got home from our honeymoon, we went to the shelter and picked out Galileo, a gray tabby cat.

Two years later, Mark called me on his way home from late football practice to say that I should wait up. He walked in holding a little white kitten. We named her Guinevere and we were a two cat household.

Our first Christmas break after we bought our house, we went to the animal shelter again and found Lincoln. He was a 10 month old, German Shepherd mix with the saddest eyes and sweetest personality. He was my first dog.

Yesterday, we said goodbye to our dog Lincoln. I cried when I realized we had to make the appointment for that day and I cried at the vets office as the vet was administering the medication that would send him home.


I wrote this post in February, right after saying goodbye to my first dog. We didn’t plan on adopting another dog for a while. Then, the following month, we were sent home for Stay At Home orders for the pandemic. Two days into social distancing and I told my husband we need to adopt another dog.


A month later, our cat Guinevere got really sick and we had to say goodbye to another Furbaby.


Mona was an amazing distraction from all the bad news in the world and our sadness over saying goodbye to our cat. But, we soon realized that she probably thought we lived at home all the time and started to get concerned about how she would deal with things going back to normal. So I started looking for a 2nd dog.


They are crazy together.

Sisters, like Anna and Elsa in Frozen… (my daughters love the sister thing)

The potty training and craziness is a lot. So is the training and the digging in the backyard. But having our fur babies has helped all of us through this crazy time. And even though it’s really sad to say goodbye to them, and we know from having to say goodbye to 3 fur babies in a year, they are worth it.

Definitely worth it.

Rethinking Assessment for Mastery over Time

What is mastery?  When does it happen?  What does a grade measure?  What ‘should’ it measure?  What should go into a gradebook?  Once it’s in the gradebook, does it have to be in ‘permanent marker’?  Or is it ok if the grade is in pencil?

These are all questions I plan on exploring at my #CMCSouth Session in Palm Springs, CA, on Saturday, November 16, 2019.

I don’t promise to have all the answers.  I don’t think I have even most of the answers.  But I think the conversation surrounding these questions is important enough to have, because our students are suffering under our grading practices.

What are we trying to teach our students?  What do our grades communicate to our students about our beliefs in their ability to be resilient, to persevere, to learn deeply over time, to make mistakes, to learn from their mistakes, in their potential as human beings, or hope that they can achieve?

I want my students to learn the tools for success for their own learning of mathematics so that no matter who is their teacher next year, they can be successful.  Education isn’t being done to them, they are active participants.  They need to become experts in their own learning.  Rethinking assessment puts them in the driver seat.

Learning takes time.  And mathematics is sequential.  So, if students need a strong foundation to be successful at the next level, then we need to give them time to show mastery.  Why would we penalize those that take longer to master a topic, if they eventually master the content?

My best friend in high school took her driving test twice.  The first time, she failed because she did one of those automatic fail things.  Does that mean her driver’s license is a lower level than mine because I passed it the first time?  She also got a very high score on the SAT the first time she took it.  I took the SAT three times before our scores were similar.  Did the colleges penalize me for taking the SAT three times?  Did I get a “minus” on my SAT score to show that it took me longer to get that score? NO!!!!!!!

Over that past 7-8 years, I’ve changed my teacher practice to reflect the new standards and mathematical practices.  I asked more open-ended questions, included tasks with a low-floor and high ceiling, put students into groups, got them up on whiteboards to do interesting math, etc.  But here is the tough question, we all need to consider.  Does my assessment practice match my teaching practice?


10 things I wish you knew as my students

Earlier this month, I saw a thread on Twitter titled “What I Wish My Teacher Knew” from the inspirational Mrs. Hall @MrsHallScholars and then read her blog post Dear Scholars I wish You Knew….  I believe 100% that in order to teach my students math, they need to trust me and that trust is founded on a relationship first.  So I need to let them in first.

I wrote this letter to them on the day of their first test.

Dear math scholars,                                                                                           September 10, 2019

I am writing you this letter to share with you 10 things I wish you knew about me as your teacher.


  1.  I wish you knew that you are the reason I love my job.  You are my reason why I come to work every day and think about math and how to teach math constantly.
  2. I wish you knew that my daughters are 8 and 3 and they are also the reason why I work so hard every day.  I want to be their example of a strong woman who is passionate about her work and is a lifelong learner.  
  3. I wish you knew how difficult it is to parent a 3 year old!  She is adorable and funny and also loud and frustrating and throws lots of tantrums right now.  So if I come to work tired, it is because she is in a difficult stage right now. (If you don’t know about 3 -year-olds, go home and ask your parents what you were like at that age.)  
  4. I wish you knew how fun and amazing math is.  It’s puzzle solving and making mistakes and thinking and arguing and being creative.  I hope you get a glimpse of this side of mathematics in this class.
  5. I wish you knew how fast high school goes.  Don’t be in too much of a hurry to grow up. You are only this age once.  Enjoy this time at school with your friends, learning about things but also figuring out who you are and what you want to do when you grow up.  
  6. I wish you knew that it’s also ok if you don’t have your life figured out right now.  There will be lots of opportunities to change your mind about your path, to change your major, to switch schools, to fall in love with a hobby, etc.  I’ve known I wanted to be a teacher since the 3rd grade, but that is rare. And it’s ok if you don’t know yet.
  7. I wish you knew that my only regret in college was that I didn’t study abroad in a Spanish speaking country.  I let our family’s lack of resources stop me. I could have researched financial options, etc. I’ve never had the opportunity to do that again, and it’s the only thing I regret.  But, I learned from that experience that I don’t want to live with regret.
  8. I wish you knew that if you focus on learning the content in this class, your grade will follow.  It doesn’t always work the other way around.  
  9. I wish you knew that for my New Year’s Resolution this year, I set a goal of reading 52 books (1 for each week of the year).  I enjoy reading for pleasure and just finished my 32nd book this past weekend.
  10. I wish you knew that this room is a safe place for you to make mistakes and learn.  And I hope you know that if you need an adult to talk to, you can speak to me about anything.  Also, every adult on this campus is a mandated reporter, so if we suspect that you are in an unsafe position, we are obligated to report it.  This isn’t to get anyone into trouble, but it is to guarantee that the children in our care are safe. I want you to be healthy and safe.


I am fortunate to be your teacher this year.  I look forward to working with you and seeing everything you accomplish.


Mrs. Verti  

{On the notecard I will give you, please write a few statements you wish your teacher knew about you.  Start each statement with “I wish my teacher knew….”. If you want to make it anonymous, that is ok. }

Even though many of my students responded anonymously, I will not share what they wrote here.  Many were funny, heartbreaking, sad, hopeful, and a lot of other descriptors.  Some described past experiences with math that were good and/or bad.  Some described outside responsibilities that are mind-boggling for any high school student. Some describe hopes for their future and fears about leaving home in the next few years.  All seemed open and honest.

I am now officially 1 month into my 17th year as a classroom teacher.  It’s getting more difficult to learn another group of names and more difficult to muster up the motivation to grade those quizzes, and I’m feeling older and less sure in my ability to relate to some of their interests in music and shows (lol)… but as I think about the next 13ish years of my career, I still love my job and wouldn’t want to miss 1 day with my students.

Whose Classroom Is This?

This picture appeared on my FB memory feed earlier this week of my teacher desk from 6 years ago. It was back to school and I was ready for my students.

As I look at it now, it makes me wonder what is communicated to a student who walks in on the first day. I’m the teacher. This is my work space. I need all this space to do my important work.

Fast forward to what my room looks like now… (ignore the clutter, my Marie Kondo post before and after will be coming soon😉).

But this classroom isn’t really for the important work I’m going to do here. And this space isn’t about me.

This space is for my students and the important work they are going to do in this room.

Who’s classroom is it? My name is on the door, but this is their classroom.
