We had a few slides to introduce MathHappens to the group and then dove right in to a hot topic, redistricting or Gerrymandering. We just had the proposed new Texas map released, but none of the negotiated changes that came the next day on the 14th, so there were real examples of all 4 types of Gerrymandering which are cracking,

## Take and Make: Platonic Solids Coasters!

Plain Platonic Solids are pretty cool – fun shapes, interesting properties from side type: triangle square and pentagons; number of edges; number of faces and more. But they are also plain. Fall intern and UTeach Maker, Maddie Wallace took on the challenge to make some accessories that would create a way we can sort them, and match the objects to

## Make: Education Forum Presentation Sept 25

Thanks to the the Make: Education Forum for a great conference! From the Q&A: The slides I presented are available here. One book I really recommend, Ernest Irving Freese’s Geometric Transformations by Greg Frederickson. The book has had written plates by an architect that can be recreated in Corel or other graphics software. Some of the designs are great for

## Take and Make: Conic Sections Model

Turns out you can use CorelDraw to reverse engineer the parts to a conic section model. The files are here, please help yourself. I cut ours out of 1/8″ wood so the slots are that size – you may need to adjust. If you want a model we may be able to send you one for free. Please fill out

## FAB16 Conference: Making and Math

Interns Saurav Gandhi and Anh Nguyen co-presented the “Making and Math” session at the FAB16 Conference. They presented several of the math models we have constructed over the years including Koch Fractals, Mini Unit Circles, and Curve Stitching. Participants were shown how they can get creative with topics in Math by participating in making a Fractal Collage (see image gallery

## Voronoi at the Minnesota Landscape Arboretum

We’ve been working closely with the Minnesota Landscape Arboretum in creating activities and models to accompany the Beehive they have on site. There are a lot a mathematical concepts that can be taught in relation to the way beehives are constructed such as tessellations, Voronoi diagrams, area, and perimeter. We can’t wait to see how they use these activities and

## Take and Make – Voronoi Flipbook

After talking with Minnesota Landscape Arboretum, we began searching for new ideas to interact with Voronoi Diagrams. During our pre-pandemic presentations and events we allowed people to interact with a Voronoi simulation that had been posted on Wikipedia. https://en.wikipedia.org/wiki/File:Voronoi_growth_euclidean.gif While brainstorming we decided to buy a flipbook kit and test out what we could do with them. One of our
