So Far, So Good!

I am loving the TVs!  My classroom feels bigger, it has been staying cleaner (My custodian also says it is easier to clean – and he is the most important guy at school!) and students aren’t complaining about not being able to see.  I had the opportunity to use them several ways this week.  I showed Jo Boalers’ newest video (The Importance of Struggle), I displayed classwork problems from the book, I went over homework questions, and I showcased student work.

We spend a couple of weeks towards the beginning of the school year going over Algebra Tiles. This week we focused on how the tiles can be put together (only matching side lengths can be placed next to each other), area and perimeter, how they can be combined into piles of like terms, how to show expressions with them and finally, how to show expressions with them on an expression mat. 

When students first see the algebra tiles, all they want to do is play and build with them!  They stack them, make larger composite shapes, make patterns, and yes, sometimes they even throw them across the room (ugh!).  So I let them build… with one rule:  Only side lengths that are the same (that is, EQUAL) can touch.  I do this so they get in the habit of building things that way (it is beneficial later in the year when we do more with the tiles.)


About halfway through the last school year I allowed students to write on the tables with dry erase markers.  I was looking for a way to get students more engaged in one particular lesson.  While I do have large whiteboards for them to use, they can be difficult to work with because there are usually things on the table that prevent them from lying flat.  I also have small boards, but students have a hard time fitting everything we are doing on them.  I decided to start out allowing it this year.  I don’t encourage it everyday, as many things do have to go in their notebooks.  I found that it works very well when we are using manipulatives that can be labeled.  

This year, I had students write their expressions on the tables and build them with algebra tiles.  Rather than print expression mats (I misplaced my laminated copies when I packed up my classroom last spring!) I had students draw them on their tables too.  Students really got into it!  And just like last year, I saw that students who don’t always actively participate were writing and building expressions!


I have to admit, I have a bit of an obsession with technology!  I walk around my classroom with my camera (err…phone) in my pocket so I can take photos of what is happening and showcase student work.  I also utilize Snapchat in my class.  I make it clear to my students that I do not add them as friends.  I use my story to post the daily homework assignments, remind students of upcoming tests, link videos of solutions to homework or review for tests and showcase what we do in class.  I sometimes forget to put things on my story, but students are great at reminding me.  Whenever they see my phone out they ask about being featured on my Snapchat story!  I try to add fun effects like in the example below. 

Two students asked to demonstrate how -(-2) becomes 2 using the algebra tiles and expression mat.

Week One

The first day of school is Freshman only and filled with opportunities for them to learn about teachers, building policies, and schedules.  It was a fun day for everyone!

My daughter is a freshman at my school this year.  She stopped for a moment for me to take this picture while she was on her building tour.  The freshman are separated into small groups with seniors leading them through the basics of high school life.  My daughters group received various animal headbands and goody bags with treats from their leaders.

We started our first regular class day with with team building activities.  In Algebra we did the Cup Stacking Challenge.  The TVs worked well to project each challenge as the students were working through them.  I modified the challenge a bit, as I set a timer for each challenge (I varied the time limit for each one) and had every team complete them one at a time.  The activity went well and students really seemed to enjoy it!


I discovered right away that I needed to adjust how I set up the projecting in my classroom.  I had the projector displaying the same thing that was on the student TV screens but I wanted to be able to display a timer instead.  I ended up connecting my iPad to one of the HDMI ports on the projector.  It isn’t ideal (there is a cord hanging down from my projector) but I left it there and it will work for now.  I am not sure yet if I want to order a long HDMI cable (to run through the ceiling to my desk) or a separate AppleTV or maybe just a another VGA to display what is on my computer. I think I’ll give it a bit of time to see what my needs are and then decide.  I also decided that it would be great if my switch from PC to AppleTV had a remote control!


In Algebra Resource we completed the Marshmallow Challenge.  This challenge involved building a freestanding spaghetti tower with a full size marshmallow at the top.  Students found this more challenging than they first anticipated but were able to work through the challenge.  


I hand out Name Tents with a feedback form on the first day of class.  I got the idea from Sara VanDerWerf (check out her blog here.)  Students write their name on the outside of the tents.  The inside has a section for them to write something to me each day.  They can ask a question or tell me something about themselves or even draw me a picture.  I spend hours each day replying to every comment/question/picture.  I found that is worth putting in the time to get to know my students.  Some students really love writing back and forth every day and others struggle to write anything.

We use CPM at our school.  This means our class time is spent working in teams.  With my new arrangement I had to add two new roles, this meant that the placemats I used in the past (with only 4 roles) didn’t work this year.  I was trying to figure out how I was going to set up my teams when I remembered Paul Jorgens, another Desmos Fellow, told about his random grouping strategy.  He referred me to an article about it (which can be found here.)  and I decided that I would give it a try.

I made cards and randomly group my students every day as they walk into class.  I am not sure yet if I am going to continue to do it everyday, but so far it seems to be working well.  I am hoping that students will learn each others names faster and get to know each other a little bit better.  I have five teams, so the numbers represent the table/team number.  In addition to the number, I put a team role on each card.  Students take on the role on the card each day.  Word was acting strangely when I made the cards, so I ended up having to make each table set one at a time and saving them as .pdf files, then changing the team number and repeating.  I have attached both the Word and .pdf file.

My first blog!

Here I am, writing my first blog.  It has not been an easy process.  Everything I read online said the domain name was the most important aspect of a blog.  After struggling to come up with something all day, I enlisted the help of my friends!  I finally settled on a suggestion and went with SamDesMath.com.  I hope I chose wisely!  Now, on to the real reason I started all this…


If you know me, then you know I am a bit obsessed with Desmos and technology.  I decided to try something new in my classroom this year.  I have attempted to turn my classroom into an Active Learning Classroom.  My students have always worked in teams, but this year will be a bit different.  

I spent my Sunday before the first day of school setting up 5 groups, each one complete with their own 40″ TV’s and hdmi cables.  Students will now be able to see everything projected right in their teams, without having to break their necks trying to see the front of the room!


Front of the classroom.  
I have traditionally projected onto the whiteboard so students and I can write work on the board.  Think of it as a low budget smart board, where you have to take a picture of it when you’re done to save it!

I have a classroom set of Chromebooks that students can use for Desmos and their ebooks.  There are also two stacks of whiteboards for students to use.  There are 2′ x 2′ boards as well as smaller 12″ x 9″ boards with a grid on one side and white on the other.  Students are also encouraged to write on the tabletops with dry erase markers.

This screen appears yellowish because the cable is bad.  I purchased the VGA cable on Amazon and it is defective.  I will get a new one eventually, but this will have to do for now.

You can see my supply station in this picture.  Students can get materials from here whenever they need them.  *TIP* – Notice the small golf pencils in the blue bin on top?  They are cheap!  I buy a box and dump it into the bin each year for students that forgot a writing utensil.  The best thing about them… students don’t walk off with them!

This wall has posters that describe each of the math practice standards (you have noticed them on another bulletin board in a different picture).  I also have The A-List Essential Academic Words poster on the door.  Every one of those words is used in math education!

The biggest downfall to this new classroom setup?  Only having 5 teams!  Our curriculum recommends teams with four members.  Depending on my class sizes, I may have teams with six members.  I am going to try it out, see how it goes, and maybe try to squeeze in one more table/tv if things aren’t working out.  

With up to six members, I had to come up with a couple more team roles.  I already have Facilitator, Resource Manager, Task Manager, and Recorder/Reporter.  I have decided to add a Technology Manager and a Floater.  The Floater will be a flexible team member that will join a different team in need, one that has fewer than five members, and take on the missing role at that table.

In addition to being able to project what is on my computer to each team, I can also use  a switch to project my iPad and display through my AppleTV.

Here you can see what my classroom setup looks like and how I can teach using my iPad and AppleTV.

This video shows how students can use the hdmi cables to project their eBook and Desmos eTools.

Tomorrow is my first day back.  Freshman only, so it won’t be a normal school day.  We only have students for a few minutes as they learn how to navigate the building and their schedules.  Here’s hoping all goes well!
