The method can be learned individually, or by whole class groups with teacher support.
The KnotPlot Site
Here you will find a collection of knots and links to explore, viewed from a (mostly) mathematical perspective. Nearly all of the images here were created with KnotPlot, an elaborate program to visualize and manipulate mathematical knots in three and four dimensions.
Lathisms (Latin@s and Hispanics in Mathematical Sciences)
Lathisms highlights the wide spectrum of research and mentoring contributions of Latin@s and Hispanics in different areas of the mathematical sciences.
The Mathematics of Juggling
Juggling has advanced enormously in recent decades, thanks in part to the mathematical study of possible patterns. The late computer scientist Claude Shannon was also an avid unicyclist, juggler and tinkerer. In the early 1980s, Shannon published the first formal mathematical theorem of juggling, and mathematicians have been fascinated ever since. You can find a great video about the math of juggling by National Math Festival presenter George Hart as well!
Mathematically Gifted and Black
This site by four young, gifted, and black mathematicians was created to share the accomplishments of their mentors, colleagues, and friends. The mathematicians highlighted here have made significant contributions in research, mentoring, and teaching. This platform provides access to the diverse and dynamic community of black mathematicians.
NASA’s Modern Figures
The blockbuster film Hidden Figures, based on the book by Margot Lee Shetterly, focuses on the stories of Katherine Johnson, Mary Jackson and Dorothy Vaughan, African-American women who were essential to the success of early spaceflight.

When you take a digital photo, your camera measures the amount of red, green and blue light hitting each pixel, ranks them on a scale from 0 to 255 and then records those values as a spreadsheet. 2017 Festival presenter Matt Parker found a way to actually open digital photos as spreadsheets in Microsoft Excel or similar programs. Upload a photo and instantly download it as a real spreadsheet, and learn from Matt’s experiments!
The Scale of the Universe
Zoom from the edge of the universe to the quantum foam of spacetime and learn the scale of things along the way!
Tessellations are symmetrical designs which can fit together in repetitive patterns like simple jigsaw puzzles. These fill a surface, usually a 2D plane, without gaps or overlaps. Brick walls, tiled floors, and the honeycomb in bee hives are all tessellations. You can learn about and see tessellations made by pros and amateurs, both adults and kids, or submit your own designs.
Mathematics is a creative subject, involving spotting patterns, making connections, finding new ways of looking at things and using what you already know in new contexts. Wild Maths has games, investigations, stories and spaces to explore, where there are discoveries to be made. Some have starting points, some a big question and others offer you a free space to investigate and develop as a mathematician.
