#TurtleArt explorations with Julian Altschul’s Class IX Geometry students at @BrearleyNYC. #MathChat #ArtsEdTech #STEAM #STEM

I’ve had a lot of interesting conversations with Julian Altschul (one of the fabulous members of Brearley‘s Math Department) over the last two years. I wondered if he’d be interested in taking his tessellations unit into the 3rd dimension, and we discussed various tools we could use for a 2D to 3D transformation. He and I are both longtime fans of Geometer’s Sketchpad, Logo, and Scratch. I suggested trying out TurtleArt since it’s a clean and simple way to make Art while flexing their computational thinking skills. Julian offered a couple of days this week for me to join his Class IX Geometry students and tinker with them.

Yesterday, we began by examining the TurtleArt menus and blocks, constructing simple polygons, and then tessellating shapes. We talked about procedures and loops, and students were tasked with exploring and coming up with interesting designs for homework. Today, girls shared their designs (as PNG files) with the rest of the class, and we peeked at their code and considered ways to make their program as efficient as possible. Here are some initial doodles:

Here’s an example of the code powering the flower drawing below:

Then, something serendipitous happened, and a student shared the “rainbow thing” file below. After opening the file, I immediately hit the clean button to clear the screen in order to watch the drawing evolve before our eyes, but only one spiral popped up on the screen.  The student explained she had manually layered spirals — each with a different color and different radius. It was a perfect segue to discuss how to enhance her code with variables (and more math!) so her fully intended design would bloom automatically. Another student talked the class through how to use the box1 and store in box1 blocks to assign and revalue variables. It was super exciting!

I suggested that students convert their PNG to an SVG (using this website), import their SVG into Tinkercad, resize if necessary (including giving their design more height), and export an STL for 3D printing. Julian is thinking that will be their next assignment…

Here’s a link to an earlier post about a TurtleArt workshop I attended last year which was led by Artemis Papert and Brian Silverman: https://karenblumberg.wordpress.com/2017/03/11/turtleart/

Love this Lenape toy project at @BrearleyNYC launched by @LuigiTeaching and the Class II Teaching Team. #MakerEd #elemaker #elemedchat #STEAM #PBLchat

Last week, Class II completed their Lenape “buzzer” toy project. Luigi Cicala (@LuigiTeaching) is an amazing artist, teacher, and Director of the CoLab, The Brearley School’s soon to be launched makerspace. In anticipation of having an actual physical space dedicated to making, fabricating, and project based learning, Luigi has been developing creative, integrated, and thoughtful STEAM-rich projects with faculty across multiple grades and disciplines. With this in mind, Luigi ideated a variety of projects to correlate with Class II’s study of The Lenape. This year’s chosen project was to create a “buzzer” toy — I totally remember making these as a kid with yarn threaded through plastic buttons (or drilling holes in a wooden disk). Now that we’re well into the 21st Century, these students used an iPad to design the button shape that were 3D-printed for them.


Students talked about shapes and symmetry while creating paper designs with Luigi and their classroom teachers, Rebecca Chynsky (@rchynsky) and Betsy Warren. Additionally, girls could use paper divided into quadrants to sketch a design to gain a sense of symmetry and test for it by folding along the lines (or axes). While the concept of symmetry might not be readily understandable, folding a shape and seeing if it overlaps fully (either up/down or side/side) is a fun exercise. See examples of Marina Jackson’s folded sketches in the photo below.img_0012.jpg

In computer class with Virginia Avetisian (@vavetisedu) and Marina Jackson, students used Doodle3D on the iPads to sketch a shape with their fingers, give it some height, and include two cylindrical holes (like a button). These were exported as STL files and printed using our Ultimaker Original+ printers which were built from kits a few years ago by upper school students. I helped with the actual printing and spent many hours over the next few weeks ensuring each student’s digital sketch was transformed into a plastic “buzzer” for their enjoyment.


Here’s a video of one of our “buzzer” toy prototypes in action!

Pics from Day 1 of #Construct3D and @DukeU’s @InnovionCoLab Studio. #MakerEd #STEMed #STEAM

I’m at Duke University for the inaugural Construct3D conference sponsored by Duke, Ultimaker, Autodesk, and ShopBot! Many thanks to co-organizer, Liz Arum, for encouraging me to attend. Below is the description from their website:

Construct3D 2017 is a national conference on digital fabrication focused on “3D printing” for higher education,  K-12, and community education. Join us as we explore ways to foster student engagement, support research, and improve understanding using 21st century technology.

Construct3D 2017 aims to bring together educators from a broad range of educational contexts to exchange ideas and innovation — to accelerate adoption and exploration of 3D printingConstruct3D offers educational pioneers opportunities to shape the implementation of 3D printing in education in years to come.

After a walk and a biscuits and gravy lunch with Ian Klapper of City and Country School, we made our way to Duke’s Technology Engagement Center for workshops and a tour of the Innovation Co-Lab Studio by its director, Chip Bobbert. Photos of the Co-Lab‘s awesome space for digital fabrication are posted below. Check out the mesmerizing wall of Ultimaker printers as well as laser cutters, CNC mills, 3D jet printers, a vending machine of engineering tools, and other tools that make me happy including a vinyl cutter and sewing machine.
