Tooth Traditions Around the World

Silvia Tolisano of the Langwitches Blog shared in this post how a teacher from Argentina is trying to help her first graders learn about the “tooth” traditions of other countries.  Students are invited to add to this Flipgrid their own stories about what happens when they hit that favorite milestone of losing a tooth. Similar to the other lessons that I’ve shared that help students to learn about commonalities and differences throughout the world, this is a wonderful idea for crowd-sourcing knowledge from our young people about a topic that means quite a bit to them!  Unfortunately, there is a disadvantage for those of us who are mono-lingual, as several of the videos that have already been shared may be in a language you do not know.  (I tried using Google Translate on my phone with some interesting results…)   Maybe including some hand-drawn pics like the one below might help.

I enjoyed hearing Maggie H.’s comparison of England and India (I think my students will be horrified to hear that some children plant their teeth!).  Considering the wide variety in monetary value that teeth seem to bring just within my tiny class, it might also be fun to research the currency exchanges mentioned and do some math along with your geography lesson.

TV Tomfoolery

The final math Digital Breakout that I made for my online students (4th grade Gifted and Talented) for this year is TV Tomfoolery.  In case you have missed the series, here are links to all 5:

You can e-mail at engagetheirminds@gmail.com if you need the answers.  However, I that you consider not getting the answers so you won’t help your students too much.  It’s fun to do some of the challenges as a whole class so you can verbalize your own problem-solving steps with the students!

The Beauty of Spirals

My 4th grade students are currently studying mathematical masterpieces.  I love showing them examples of the intersection of math and art.  When I saw a tweet yesterday morning from @TheKidShouldSeeThis with a link to the video of John Edmark’s spiral geometries, I knew right away that they would want to watch the video.  It weirdly connected with the magical drawbridge from yesterday’s video, so I showed that part to them first.  We have already talked about Fibonacci and the Golden Spiral, so they immediately found ways to connect both videos to their learning.

Since the students have also been using Scratch coding, I found a Scratch project for making spirals.  First we looked “inside” to decipher the code.  Then the students explored running the program.  After that, I talked about creative constraints, and gave them the challenge of changing one and only one part of the code to see how it made the program run differently. They recorded the results of their new programs and the class tried to guess what variable each student changed based on the videos.  Then I gave them time to freely remix however many parts of the program they liked.

This was one of those times that the students could happily have explored all day.  It was their first time remixing a program, and they delighted in trying to take it to the extremes by putting ridiculous numbers in to see how large or small or non-existent their spirals became.  Some of them created spirals so tiny that they appeared to be flowers blooming as they popped on to the Scratch stage.

And I still haven’t blown their mind with this Vi Hart video yet.  With the school year almost over, we may have to take this unit into their 5th grade year.  There is so much beauty in math, and we have barely scratched the surface!

Scholastic Beasts

I am currently offering an online Google Classroom for some students in our district that assigns them one Digital Breakout (Math) a week for 5 weeks.  “Scholastic Beasts” is the 4th one in the series.  For the first three, you can see:

All of these are designed for 4th grade gifted and talented students.  As with the others, you can e-mail me at engagetheirminds@gmail.com with the title of the Digital Breakout if you need the answers – but I find that it’s better to not help your students too much!

Kaled It!

I overheard some of my students talking about a cooking show called, “Nailed It!” and decided to make my next Digital Breakout based on that title.  Because we have been having a few glitches with Google Sites in our district, I decided to use Weebly to create this one.  “Kaled It!” is a bit harder than my 1st and 2nd Digital Breakouts.  Therefore, I thought I would give you some of the clues I just posted for my Google Classroom students: Lock 1 can be answered with “The Milk Dilemma.” Lock 2 will be found on “Shopping.” Lock 3 is answered using “Kale Pesto.” If you want to answer Lock 4, then carefully explore the “Meet the Contestants” page.

As with the first two Digital Breakouts I designed, teachers can e-mail me at engagetheirminds@gmail.com to receive the answers. (Please put the name of the Digital Breakout in the Subject line.)  However, I agree with the one teacher who told me that she enjoyed not knowing the answers because she didn’t help her students too much!

Feebo, Not Chee

Feebo, Not Chee is my latest attempt at doing a Digital Breakout.  Like the previous one, this one is designed for 4th grade students.  Ideally, they would work on it independently.  The pages are not in the same order as the clues, and there are a couple of links to external sites on this one.  If you are an educator who needs answers to this breakout, please e-mail me at engagetheirminds@gmail.com

Artful Maths

Yesterday’s post about the new OK Go Sandbox made me think about this blog I bookmarked awhile ago.  There is something about the juxtaposition of art and math that fascinates me, so the title of Artful Maths immediately caught my eye.  Under the “Resources” menu you can find, “Mathematical Art Lessons,” which is where I learned of the existence of “cardioids.”  Most of the lessons are accompanied by Powerpoint presentations and downloadable handouts.

Another section of the site I like offers ideas for “Puzzle Games.” This is where I found out about a free iOS game called, “Fibo,” which I am still trying to figure out.  Not all of the game suggestions are free, but you may discover a few new ones that cost little to nothing.

Artful Maths also includes links to origami resources and other mathematical interests.  There are quite a few Christmas decoration ideas on the blog, which I will need to remember for later this year.

Thanks to Clarissa Grandi (@c0mplexnumberfor sharing all of your awesome ideas!
