We teach Integrated CPM Math 2. We struggle to get through the material that is skillfully articulated and struggle to keep our creativity while being true to the curriculum.

Sometimes you need to give your students more exposure and time than the curriculum has laid out. (As evidenced by the number of groups who got the same problem wrong on the test) Or your colleague is unhappy with the lesson described for tomorrow and it is 4:30 pm and she's been there since 6:30 am and can't stare at her screen for another second.

Like my friend, Brian http://www.mrmillermath.com/ said once, "sometimes you just need a worksheet." Here are two very different, quick ways my colleague and I handled facilitating learning in our CPM Math 2 classes that added to the curriculum provided.

Review of a concept: It took about two minutes of hunting for images before I gave up and instead decided to use a notebook warm-up instead. I hoped that as students copied the notes, they would observe what they needed.

Directions: In your notebooks for Day (27), Draw 6 squares, copy the images, what conclusions can you make about the pairs of triangles? (We first recalled the triangle congruence and triangle similarity theorems) Take 3 minutes by yourself and see what you observe, then open the discussion to your table group. What can you conclude given only the pictures and no other information?

Oops should say "Triangle" pair. 


Introducing a topic:

This teacher was uncomfortable with the guided lesson for discovering "slope triangles give the same slope angles in our CPM text." She needed something more to inspire her students to "discover" the lesson's goal.

After some running between rooms, here is what she came up with. Nothing short of brilliant!

Textbook:


Danielle's Tweak:
Give the students some index cards with the same slope in equivalent fraction form. Have students graph them on horizontal, first quadrant graph paper. Have students use protractors to discover the slope angles. Go find the other people with the same slope angle as you have. What do you notice and wonder?



I am one of the luckiest teachers alive. We are certainly better together.
This summer at Twitter Math Camp my morning session was Talk Less, Smile More hosted by
Mattie B and Chris Luz. Our learning was about engaging students in debate style conversations to get them thinking and sharing ideas. The notion of course is to start low entry and let the student's thinker uppers go wild.

We had a sharing morning for the faculty last week of anything that is new and useful to know about kids, programs and curriculum. (I teach high school, there are 96 teachers) I was so excited to share what I had learned. I was given 10 minutes. (and it turns out I gave the only interactive presentation, really?)

I did a lovely activity I learned about at this session that starts with an Estimation 180.
How many people can fit in this elevator?
I asked the audience to think silently and write their number down (no cheater pants). I then cold called teachers (come on they are teachers) (and I got to rat out a history teacher who said "I don't do math," "Oh yes you do, I said, Everyone is mathematical, you wear a fit bit, you know how many students you have, you know how long it takes you to get to through your lessons etc...) to give me their estimates while I typed them into Desmos.  Everyone loves the visual median line! Thanks Nicole Paris (@solvingforx) for showing me how Chris and Mattie did this on Desmos!



I then called the teachers onto the stage (we met in the theater) to take a stand on either side of the median. Then then were asked to state their CLAIM and finish the sentence with My WARRANT is...

Let the fun begin! I ran back and forth with the microphone, one low, one high, until all the participants were heard. So much fun! One math teacher said, I noticed that the gentleman took up about a floor tile, so I counted all the floor tiles and pieces of floor tiles and estimated 30. One of the art teachers said this, "I was so overwhelmed by the news of Hurricane Harvey, that I just imagined all the babies and incubators, stacked up in the elevator, plus an attendant, that is how I got 131.

Then the big reveal:


That was Wednesday morning and even Friday on my way out for the long weekend, an English teacher stopped me and said how cool that lesson was. (and science teachers, and art teachers and special ed teachers have been telling how much fun they had and much they wanted to try it in their classrooms. )

I talk to and work with at least 80 teenagers everyday (we are on block schedule so we only have half our kids per day--didn't want you think we get to have reasonable class sizes or anything) and my knees shook for 3 hours afterwards.

Let me know if you use this lesson and how it goes!




A big topic at TMC this summer was Social Justice and Equity. We looked at who we are, fairly white, and wrestled with how do WE represent our students. Grace A. Chen and Carl Oliver gave us platforms to express ourselves in honest and fresh ways.

How do we become Allies? The most popular solutions were to "push in" observations about where stereotypes come from to grow awareness and compassion and to be meaningful about our "whys" and our speech if we teach in mostly white schools and "push out" observations about stereotypes and be meaningful in our intentions and speech if we teach in diverse schools. (please let me know if I have this correct TMCers)

As I was sitting with this information and getting ready for school, I was listening to Pod Save the People with @deray interview @Common. It was a very moving conversation about change. Deray asked Common what advice he could give to young artists to use their voices to make change. "Ask folks what they need." Deray echoed, that sometimes well meaning people think they know what folks need, but that is not what they want or need. So now he always asks, "what do you need?" Common said it is "empowering" for people to listened to be part of the solution. Both agreed that asking was the key to becoming an Ally.

With all this in mind, on Monday it was time to ask for Question 2 on my student's name tents. I scrapped, "What question do you have for me?" and changed it to "What do you need from me?"

Ernesto says, " I am friendly, but slow at math, I just need patience."

Donnie says, "I need help if I don't understand something."

Serah says, "I need you to be understanding about my struggle with anxiety and depression."

Christina says, "I need you to be organized."

Lorraina says, "I need to be valid victorian." Wow. There is a challenge!

These are teenagers speaking their truths. And I get to be fortunate enough to let them know through my words and actions that I am their Ally.

 Carlos let me know how important this question is:

Just when I think I am the giver, I get so much more.

This year may be different because our HS has adopted CPM Integrated curriculum. CPM does a lot of upfront team building, which is what I naturally do. I hope I will have time to play around with my beloved openers and try some new ones from #talklessam.

I start by having my students make a name tent. This year I will use something like mathequalslove.blogspot.com, with room for feedback and questions on the inside. I like name tents because I use them for random grouping, learn student names, and giving the students an opportunity to express themselves. I usually ask them for birth order, and favorite something. I found this slide from last year:

I saw that I used the Right Hand Side for a Bell Ringer that was a visual pattern and I used the Left Hand Side for an Exit Ticket that was to answer: I notice…I Wonder…Some questions I am considering are "One thing you want me to know about you," " What is making you happy this week?" and "Tell me something I don't know, it could be about you or about the world at large." (Taken from Dinner Party Download Podcast)

After Name Tents and Warm Up, in Geometry, we start with WODB. (Which One Doesn’t Belong?) I get the students used to Upper Left, Lower Left, Upper Right and Lower Right by doing my version of Lines and Blobs, but only use the Blobs. I name the corners by preferred genres of movies, more likely to be (ie playing  a video, at the beach, texting, etc) Have students notice who is in the pod, so that they know who their peeps may be. (I also use these pods to make the next days seating charts!) I talk to the kids in the Blobs, ask them why they are there, I also poke around for folks to speak up when I ask if anyone is willing to share why they are there. Here are some of my favorite WODB to start with:
and



The 2nd day, I use an icebreaker I used in a “My Favorite” at Twitter Math Camp in 2016 . Check out the power point here. Basically from asking a group of 4 students to come up with a single favorite movie, book, and game, you gather a list of how group work gets done. It isn’t always the ideal; time constraints, loudest gets the voice, yet it is totally real. And then you get talking points. What is ideal? What does bullying feel like? How would you most like to get group work done?

Speaking of talking points, I want my students doing more talking and me doing way less, so I am going to try to set that culture up early. I will have the students do a silent response, a talking point, explained here best by Elisabeth @cheesemonkeysf, and a delve into this article, The Myth of "I am Bad Math," that is super revealing when you have the students first respond to the question about their beliefs and then let them read the article and observe if there has been a shift. 

What do you do that sets the norms in your classroom?






I attended my 3rd TMC (Twitter Math Camp) this summer in Atlanta. I must thank Sam Shah for blogging all those years ago when I discovered the TMC, then #MTBoS and was encouraged to start blogging in 2012.

Every year there is magic in the air, and this year, from the TMC 2012 founders to the 2017 first timers, it seemed everyone had a magic wand. It turns out that very early on we made inclusivity our theme and equity our unifying passion. It was wonderful, political, and complicated.

There is no particular order to this list of goodness, just a bunch of random thoughts and one or two regrets, as I left before the wonderment of the Sunday morning session. If you are lonely in your math world, please consider joining #MTBoS and venture out to Twitter Math Camp in Cleveland the summer of 2018. The folks you will meet, will become, like they have for me, my allies, mentors, colleagues and friends.

First, I wrote all my notes for this post using my purple pen from the Math Forum. Thanks, I love it.

I must thank Holy Innocentes School for their hospitality. From the bus driving director to the receptionist who liked my corduroy jumper. The folks and thoughtfulness of the building design complimented MTBoS perfectly.

The AtlantaCenter for Civil and Human Rights is a must see. Within minutes, I met my 19 year old’s future husband, the amazing young man at the information desk; articulate, smart, kind (okay, and handsome). The powerful images, (looked at the segregationist in their 3x3 matrix and they looked just.like.Trump’s cabinet—heart-sinking and disgusting), the interactive diner counter, the music, photos, artifacts, and world political freedom map were all intense, beautiful and pitiful, hopeful and cruel. My roommate and I Norma, happened upon one of two performances of The Collision Project, an original performance of 21 diverse, crazy talented high school students who work with an artistic director and a work of literary merit (This year, John Lewis’, graphic novel trilogy, March) to create a choreographed, musical, spoken word original work. For 70 minutes or so we were entranced, lifted up, and felt true hope.

TMC Takeaways:

James Cleveland’s watch. (And his energy and positivity)

Lisa and Jason Henry. Enough said.

#Talklessam, my morning session. Led by Chris and Mattie, the room was alive with the sound of well-facilitated openness, invitations to build a culture classroom of acceptance and productive debate. I am grateful to all the participants. Some highlights that show how easy it is to build in more student talk are using Ken-Ken puzzles to get students accustomed to My Claim is…My Warrant is… to using Estimation 180 to build definitive sides and let the claims roll. I also found out there is research against cold calling, take that Raul.

Universal talk of growth mindset and open invitations to take risks and #pushsend.


The explicit tone of social justice, opened up by Grace A. Chen’s keynote, “Math is necessarily political,” kept on our minds again and again, through open discussion, continued discussion, and our collective heavy sigh learning of the transgender ban in the military, renewing our efforts to be kind, warm, and inclusive.

Sam Shah’s favorite counter bell, for “math joy moments.” This is exactly what happens in my head when I listen to my favorite podcasts and my mind wonders out my mathy lens.

A special appreciation to first-times who stepped up to share a My Favorite or lead a session.

David Butler’s SQWIGLES for 1-1 tutoring.

Carl Oliver

Someone, not sure who, (please let me know) introduced the idea of “Graph of the Week,” to engage math as a vehicle for understanding.

I appreciate Graham Fletcher’s Friday’s keynote for the much appreciated humble humor and for the picture of an incredibly long Georgian worm that will gross my sister out. And thankful for his pearls, Always do a second problem for those who got the first wrong to redeem themselves, and “Vulnerability is the birthplace of professional development.” (Truly, this is why the MTBoS works the way it does.)

The willingness of folks to give up their lunch-time for more peer to peer time like the math and equity discussion sparked by Grace Chen and facilitated by Carl Oliver, (@carloliwitter) and for the Julie Reulbach ( I Speak Math) facilitated meeting of folks using CPM.

Definitely for the new folks I met, like Andrea who invited me to do the 5K fun run at Red Brick Brewery. Nothing like a fun run to understand where you are.

And for the catnaps I was able to sneak in on the chairs and benches of HIS.


That’s a wrap. If you have any questions about any of it, DM @zimmerdiamonds
