Which One Doesn’t Belong – More Photos!

One of my favorite math activities to do with students is called, “Which One Doesn’t Belong?” This was an idea that seems to have originated with @MaryBourassa, who created a website for this.  I described the concept and offered some links in this post from 2016. Recently, I saw a Tweet from @Simon_Gregg offering an entire album of over 200 WODB images for educators to use for stimulating math discussions.

Each picture set has 4 different images.  Project the images to your students, and ask them which one doesn’t belong – and why?  Hopefully, you will receive many different answers, and they will all be right for various reasons.  Because these are so open-ended, they can be used with different levels of complexity from number sense to geometric reasoning.  Encourage students to use mathematical vocabulary as they defend their choices, perhaps even making it a game where points are awarded for including particular words.  Challenge the students to try to find a reason for each one of the four to be excluded from the group, not just the first one they notice. The “See, Think, Wonder” Thinking Routine would go very well with this activity. (For more on Project Zero Thinking Routines, see this post.)  A formative or summative assessment option would be to ask students to create their own WODB challenges.

WODB is one of the 15 Math Sites That Won’t Make You Fall Asleep that I’ve listed on this post. I highly recommend checking out those links if you feel like you want to add a bit more zip to your math lessons – or just enjoy doing unusual math puzzles.  (I’m addicted to the SolveMe Mobiles!)

Two Bit Circus

Two Bit Circus is a foundation that describes its mission as follows: “We serve children in all economic situations by creating learning experiences to: inspire entrepreneurship, encourage young inventors, and instill environmental stewardship.”  The organization has aimed to achieve these goals through activities such as summer camps, STEAM Carnivals, and workshops.  Although many of these programs have had to come to a screaming stop during the last few months due to the pandemic, Two Bit Circus has not faltered in its delivery of quality content.  Instead, it has shifted to offering streaming classes during the week on topics that range from creating music to building balloon racers.  You can find the archive, already full of informational project videos they have streamed since March, here.  Note that Caine Monroy (yes – the charming young man from Caine’s Arcade) makes a special appearance in some of them.  He is a member of the foundation’s Junior Advisory Board.  In fact, according to the streaming schedule on the home page, Caine will be hosting another live session this Thursday, May 21st.

It’s clear that Two Bit Circus is making a strong effort to offer distance learning projects that are fun, educational, and mostly reliant on household supplies.  Some other resources you will currently find on their website home page are their STEAM Carnival Playbooks (currently free downloads thanks to Vans), a Bricks Playbook for Parents, and “Power Lab,” a “Print-At-Home Escape/Story Room Experience.”  In addition, parents who are suddenly finding themselves to be educators may learn some helpful advice from the “Teachers for Teachers” series that you can find here.

While the official school year may be winding down for some, the unpredictability of the next few months will probably still leave some gaps in children’s schedules.  With these resources from Two Bit Circus you can make that time fly!

Dear Data

This is another example of one of the great internet wormholes that I fall into when I read Twitter.  I was fascinated by a Tweet from Nick Sousanis (@nsousanis), which led me to an amazing book so I could interpret his Tweet, which led me back to the work of his students and a bazillion ways remote learners around the world could have fun with his assignment or other permutations of it.

Let’s start with the book.  Dear Data began as a pen pal project between two information designers on different continents.  As they explain on their website, “Each week, and for a year, we collected and measured a particular type of data about our lives, used this data to make a drawing on a postcard-sized sheet of paper, and then dropped the postcard in an English ‘postbox’ (Stefanie) or an American ‘mailbox’ (Giorgia)!”

Each postcard consists of their data and the explanation of its depiction.  The women chose all sorts of topics to record, such as a week of laughter or a week of complaints.  Though they would be collecting data for the same topic during that particular week, their pictograms would be dramatically different.

They learned a lot from this year-long project, which resulted in a book, a postcard kit, and a journal.  As Giorgia and Stefanie explain in this video, “We learned to pay attention, to live in the present much more, to be more aware of our surroundings, and empower behaviors with new lenses.

So, back to Nick Sousanis, who Tweeted that his visual communications students had come up with their own “Dear Data” projects, and gave examples of some of the results in his Tweet.  I asked Nick if I could share these on this blog and he graciously agreed. (You can click on each picture to enlarge.)

I see all kinds of potential for this with students.  For example, one of the Depth and Complexity icons is “Trends,” and it would be interesting to ask students to analyze one of these postcards, and determine what trends they see.  Using, “See, Think, Wonder” would be a great start. In addition, as Nick found with his class, assigning students to develop their own data sets can invite self-reflection and creativity.

During these unique times, when data has become a fixation for much of the world, students can also examine its importance and reliability.  As the women who completed this ambitious project say in their video, “Finally we both realize that data is the beginning of the story, not the end, and should be seen as a starting point for questioning and understanding the world around us instead of seeing it as the definitive answer to all of our questions.”

Clear the Board

Are you looking for a fun math game to play with your kids or students at home?  “Clear the Board” might be just the ticket.  Mark Esch (@mtesch) recently tweeted out the link to his humorous video that explains how to play “Clear the Board.” It is surprisingly simple with few materials needed – and lots of fun potential.

Teachers who are currently trying to get your students engaged in math remotely could try this in several ways: during a synchronous class meeting, assigned with the video to play at home and directions for demonstrating what they’ve achieved with their own combination of numbers, or something like the fun idea below from Mrs. Bogar:

“Clear the Board” is one of those activities that is easy to differentiate, as Mark Esch explains in “Clear the Board Part 2,” offering extensions to keep students challenged. (Can you figure out which famous SNL skit he and his partner are parodying in this one?)

Mark also tweeted some other suggestions:

For an activity that is similar to this, check out “Bowl-a-Fact” from YouCubed.

Chronicles of COVID-19, Part 3

If you haven’t seen the updates that I’ve made to this post, please check it out.  There have been some difficulties out there in accessing the COVID-19 Diary that I shared.  I think I inadvertently turned off editing when I tried to fix them, but I’ve turned it back on.  Unfortunately, you may still have issues if your district blocks access.

Here are two more entries from Our COVID-19 Diary by Kids Around the World.  It looks like a lot of contributors own cats, and all of them, so far, have pets!  Hmm… I’m already seeing lots of math possibilities with this project as more people add to it – graphing pet numbers, mapping locations, etc…

If you haven’t shared the Diary with your students and asked them to add to it, please do!  I would like to make this as globally inclusive as possibly.  (Did I just make up a new phrase?  I’ll have to Google that…)

Slow Reveal Graphs

If you are a fan of helping students learn how to be critical thinkers, then you will appreciate the Slow Reveal Graphs site.   Rather than presenting a full graph to students and asking them to interpret it, teachers use Slow Reveal Graphs to allow the students to discuss, think, wonder, and predict as each stage of the graph is shown – hopefully resulting in deeper learning.  (This technique is similar to the one used in the New York Times’ “What’s Going on in this Graph?” feature.) Courtesy of Jenna Laib (@jennalaib) and other contributors, The Slow Reveal Graphs website has examples of different types of graphs (Circle, Bar,  Line, etc…), many of which have links to slide decks that have already been created for the slow reveal.  “How Long Can Animals Hold Their Breath Underwater?“, for example, begins with a bar graph that has no title or labels and incrementally adds them as you advance each slide.  The slides also have suggested discussion questions in the notes.

In case you are thinking this site will only appeal to math teachers, I should note that there are three special categories of Slow Reveal Graphs: Social Justice, Save the Planet, and Incarceration in the U.S.  Of course, any of the graphs on the site can be used in multiple subjects, including ELA.

To read more about how Slow Reveal Graphs are used in classrooms, from primary to high school, visit this list of bloggers who have written about SRG’s in the past.

If you like SRG’s, consider trying Clothesline Math and Would You Rather? Math.  One of my most popular posts, 15 Math Sites that Won’t Make You Fall Asleep, has examples of these and more. Also, follow the #mtbos hashtag on Twitter for more great math teaching strategies!

STEM Cookbook

Who says that Robotics can’t be tasty?  If you believe that, then the L’Essor Secondary School Robotics Team, Team 6331 SaBOTage, would disagree with you.  The team has produced a downloadable STEM book of recipes titled, appropriately, How to SaBOTage Your Kitchen. The students researched and published this guide to preparing delicious dishes. It includes scientific health tips and explanations, and has recipes that will appeal to a variety of taste buds, ranging from “Big Bang Caramel Popcorn” to “Exploding Bacon Pulled Pork.”  To learn more about this FIRST Robotics team, located in Canada, you can visit their Robotics website.  This unusual perspective on how STEM can even enhance our cooking is a great resource for families and students who may have a more narrow view when it comes to the usefulness of math and science in their everyday lives.
