Aperiodvent, Day 15: Mathematical Present Wrapping video

In the viral YouTube hit of Christmas 2015, Katie Steckles demonstrates some of the most mathematically satisfying ways you can wrap your Christmas presents.

Aperiodvent, Day 14: Dodecahedron star lantern

If you manage to dismiss all the ads, the blog Happiness is Homemade has a post which shows you how to make a cool dodecahedral star lantern out of paper (and glue, and you’ll need a light source too if you want it to actually function as a lantern).

Aperiodvent, Day 13: Fold-and-Cut Christmas Tree

The fold and cut theorem, which states that, after sufficient folding, any shape made of straight lines can be cut out of a piece of paper in one cut, is probably the most crafts-friendly result in all of maths.  Inspired by The Aperiodical’s very own Katie Steckles’ video on the subject, Sam Hartburn has created a handy PDF with instructions for folding and cutting a festive Christmas tree shape.

Aperiodvent, Day 12: Fractal Christmas Trees

If you’re looking for a fun hands-on project that’s mathematical and Christmassy, look no further than Think Maths‘ classic Fractal Christmas trees – building a Sierpinski tetrahedron tree, Menger Sponge base and Koch Snowflake star.

Katie is running an Aperiodical advent calendar (Aperiodvent 2018), with fun maths Christmas treats every day. Behind the door for 7th December was Parabolic Sewing.

This is not unrelated to what I submitted as my entry to The Big Internet Math-Off last summer. I have been revisiting this idea ready for a class next week in my second year programming module.

Aperiodvent, Day 11: MathsJam Shout

Today is the regular monthly MathsJam date for people to meet in pubs and do maths all over the world (some are meeting next week instead – check to find your nearest). Their internal puzzle sharing sheet is snowflake themed this month, and is shared online so you can join in from home.
