Kruskal’s Algorithm Minimal Spanning Tree: Railroad Table This project was created by Sheryl Hsu for exhibit at the Almaden Quicksilver Mine and sponsored by MathHappens Foundation. Sheryl wrote us a detailed proposal that described her project, the mathematics she planned to explain and the details of construction. You can read it here. Then she built it! See Sheryl’s video where

## MathHappens @ Nature Nights at the LBJ Wildflower Center

Matt Hertel, a graduate student at UT in Mathematics Education explains the Fibonacci sequence to visitors who also learn about connections to bees, the rabbit problem, its appearance in flowers and the emergence of the golden ratio when you take ratios of higher numbers of the sequence. Over 70 bee pendants were colored over three hours from 6 – 9

## Library Math Up and Running!

We have been sending boxes of math materials, things we’ve made and others by Christopher Danielson of Public Math and Dan Finkel or Math for Love that we think will work for libraries. How do we measure success? Very unmathematically! These are some delightful quotes from a librarian whose staff created a whole program. We really appreciate

## Cinco de Mayo! We had a blast!

What a nice event at the George Morales Dove Springs Recreation Center! In partnership with the Austin Public Library we set up some stacking frames for ball pit balls, giant tangrams, provided a flower of life medallion to color, chompers (mathematical origami) and geometry kits to make your own flower of life. Many thanks to Austin Public Library and our

## Take and Make: Magician’s Rods

I learned about these on a video on Numberphile. . In the video they said the magic words “no longer available” and that was it, we had to make our own. Josephine Sheng designed these way back in 2017 I think, and we just never posted. We don’t like “tricking” people, but if you have a good half hour you can

## MathHappens at the Library- Updated!

We’ve sent materials to or provided activities at the LA Public Library, Killeen Public Library, Buda Public Library, Santa Fe Public Library, Austin Central Library and most recently the Orange Public Library and we are going to do more. Libraries are great because they are free, open and available to learners of all ages in the community, and you can

## Mathematics Programs for the Community.

We provided the Clifton Institute with some information and supplies for a Voronoi session for their mathematics program. Here’s the whole quote: People seemed to really love having a weekly series where they could come, listen to a 30-40 minute lecture, and then do a corresponding craft. It was also a great insight into how strongly grading and judgement permeates

## Take and Make: Printables to Guide your Project.

This is a transformer puzzle. The template has one side set up as a hexagon and the other side a square, but the hexagon design can still be rearranged as a square as well. Maddie Wallace made this logo for University of Wisconsin by hand. Be sure to use the link to get the PDF file. Transformer Puzzle Square to

## Cedar Creek Elementary STEAM Event!

We don’t normally go into schools for regular programming, but this was a special event and almost like an in school field trip with lots of rotations. We brought activities for 2nd graders, 3rd graders and 4th graders. 3rd graders explored designing with mirror books, 2nd graders worked with Koch fractals and Golden Ratio tiles and the 4th graders

## An Interactive Cross Disciplinary Mathematics Museum for Austin!

Let’s continue the tradition of service to education, support our students and learners of all ages in mathematics by offering free learning resources to the Austin community, support cross disciplinary programs, create and use hands on interactive models. A great opportunity is on the table. The Pease School opened in 1876 and served Austin as an elementary school for 144
