How can I exercise,reflect on my teaching, and reduce stress with my busy teaching schedule? The answer just may be found in the hottest fitness craze called the FitBit.It seems everywhere I go these days I see someone wearing a FitBit Activity tracker,and talking about how  they enjoy using it. FitBit is a very cool activity tracker that you wear and it records all kinds of data from heart rate,number of steps, distance and calories burned when you wear it. Another really fun feature is […]

This was my second year to celebrate Pi Day with my students.  During my first year of teaching, I fully intended on celebrating Pi Day, but the day ended up being spent at urgent care and in the emergency room.  So not fun.  This year, I added a new element to our celebration.  We wrote pi-kus.  The first line of the poem must be 3 syllables.  The second line must be 1 syllable.  The third line of the poem must have 4 syllables.  I didn't count on having […]

This year, I have tried to engage my students in a more thoughtful homework process. I don’t think any math teacher, ever, has been satisfied with the way homework works in their class, and I would certainly put myself in that boat. My frustrations in the past have been that students sometimes would do something wrong […]

Ravens Offensive Lineman John Urschel Explains His Mathematics Paper: John Urschel:On first read, I understand that simply the title of my new paper – “A Cascadic Multigrid Algorithm for Computing the Fielder Vector of Graph Laplacians” – can be quite daunting. Believe me, I am aware that terms such as multigrid, Fiedler, and vector are not words that people use in their daily lives. With that said, if you would like to understand what exactly this paper is about, the title is a good […]

Welcome to this week’s Math Munch! Behold the Sphericon! What is that? Well, it rolls like a sphere, but is made of two cones attached with a twist– hence, the spheri-con! The one in the video is made out of pie (not sure why…), but you can make sphericons out of all kinds of materials. […]

Schüler aus der Jahrgangsstufe 13 haben einen Sponsorenlauf für einen guten Zweck organisiert. Aufgrund verschiedener Umstände kann der nicht auf einem Sportplatz stattfinden, statt dessen wird um die Schule gerannt – das sind etwa 500 Meter Strecke. Bergauf, bergab. Auch eine Treppe ist dabei. Weil wir eine recht große Schule … Continue reading →

If there’s one thing we’re probably all agreed on, it’s that when it comes to buying and goods and services, value for money is the top priority. From web hosting to wardrobes, digital downloads to doors and windows, when we set out to make a purchase, most of us look beyond the mere price as its ...

“Have you seen the world go around?"Every human activity, good or bad, except mathematics, must come to an end. ~Paul ErdosThe 85th day of the year; 85 is the largest number for which the sum of 12 + 22+32+42+...+n2= 1+2+3+4+.... +M for some M, can you find that M?   85 is the largest such n, but can you find some solutions n,M that are smaller? (Reminder for students, the sums of first n consecutive squares are called pyramidal numbers, the sums of the first n integers are called […]

I got a new student today.  Today.  Eleven weeks before school lets out for summer.  At the end of class, the kid told me that was the first time she understood what was going on in math class for as long as she could remember.  Her presence, along with some other things I've been thinking about, prompted me to pull out my computer and write what's been on my mind...I teach in one of the lowest paid states for public education teachers. I work with unbelievably dedicated […]

Assessing math vocabulary is important because math is a language and if you don’t know the words, you will have difficulty speaking it.  Here are a couple of good links on making vocabulary assessments. Link 1 (scroll to the bottom of the page for a list of ideas) Link 2 Link 3  Also remember that […]

Tonight I'm asking you to help me write a blog post.  We have all read or heard the research that states that teacher quality is the single most important factor in student success.  Not class size, not resources, not even socioeconomic factors.  Teacher quality. That has me wondering, how do we define what makes a teacher outstanding?  What are the characteristics that an outstanding teacher possesses? Here's where your part comes in.  Please think of a teacher you […]

I know I'm super behind on blogging about lots of stuff, but I just had to blog about things teenagers say today.  I'll get around to blogging about SXSWedu and Pi Day and all kinds of other fun stuff soon!  Promise. I don't know what it was about today, but my students were saying crazy things left and right. Maybe they're always this funny and I get busy and don't realize it, or maybe there was just something in the air today. Either way, enjoy my students and their craziness! I […]

I’ve been mulling over how to introduce trigonometry to my geometry students. I think I’ve finally figured out a way that is going to be conceptually deep, and will have kids see the need for the ratios. I don’t know if all of what I’m about to throw down here will make sense upon first […]

Every year, across all grade levels, I hear (and observe) subtraction being a difficult concept for students. Not just a difficult calculation, but concept. I am not talking about reading a context and knowing if subtraction could be a way to solve it, but instead what is happening when you subtract and how does a […]

I’m a big fan of continued fractions – especially the many different ways that you can use them to help kids learn elementary math. Right now I’m studying square roots with my younger son and he’s taken quite a liking to continued fractions, too. See yesterday’s project, for example: A surprise square root of 2…

Today's warm up was this visual pattern:I explicitly asked them to colour in how they saw the pattern growing. So many of my students just count the blocks and don't even look at the pattern itself that I felt that I needed to make sure the connection is being made. Here is where we went with it:I love how this is like a little spiral within the cycle as we talk about rate of change/slope and y-intercept every week, even if our focus at the time is not linear relationships. There is also the […]
