## Austin Nature and Science Center Fall Fest Star Party

One person can make a real difference by bringing math into a family event at the Nature Center.  Emmie Chng was working solo with an enthusiastic gathering of families.  They learned how to make a plumbline, how to use a quadrant, how to make one at home and why we look to the north star to find latitude. Here’s the

## Great time presenting the 15 Tessellating Pentagons to the UT Math Circle

No paper, no pencils, just working with the shapes.  We had a ball!  Thank you for inviting us and providing a great meal Dr. Jennifer Austin!  Teachers got to take home a set of about 15 of their favorite type.  Finding the types began in 1900 with Hilbert’s challenge and ended in 2017.  Its a great story.

## MakerFaire Austin 2019- Featuring 3 Women Mathematicians

We had displays on Karen Uhlenbenk, Mary Boole, and Marjorie Rice.  Some people wanted to see a Voronoi pattern in a dragonfly wing, others designed and colored Marjorie Rice’s Pentagon # 13 and others were fascinated by Mary Boole’s Curve Stitching.

## What are tessellations?

What are tessellations? A repeating pattern of shapes that goes on forever without any gaps or overlaps. You can think of tiling a floor. Squares, triangles and hexagons are all shapes that tessellate. Mathematician Marjorie Rice discovered some very interesting polygons that tile. It is fun to color and move around all kinds of geometric shapes! See how these squares

## Enthusiasm for Math at the Austin Central Library Kids Block Party!

If you ever wondered if families, adults, kids, teens would be interested in some math on a Saturday, this should answer your question.  We brought Tessellations, and in particular some designed with Marjorie Rice’s discoveries and we also featured Lewis Carroll’s puzzles, tangrams and cipher codes.  MH team:  Kyla Kalugdan, Josephine Sheng and Lauren Siegel, and special thanks to our

## Tessellations! Gilbert Elementary Science Day

Josephine Sheng, Paola Garcia and Cassandra Gonzalez at Science Day Tessellation puzzles are a great way to spend some time with some regular and irregular polygons and as a group make some beautiful puzzles.  These are going to stay at Gilbert Elementary in the library. And we got a nice note from the principal: Thank you so much for sending

## MathHappens @ the Thinkery with Marjorie Rice Tessellating Pentagons

Favorite quote:  “Oh my gosh! I can feel my brain working”. We had a great time at the Thinkery’s Community Spotlight:  Women in STEAM.  Thanks to Halle Herzog, Kyla Kalugden and Cassandra Gonzalez.  We featured the irregular pentagon tilings and artistic butterfly stylings of Marjorie Rice. Marjorie Rice found 4 of the remaining 6 types that were still unidentified in
