Part of Maths on Toast’s ‘Stay-in sessions’, a series of creative family maths sessions delivered online September – December 2020.
For our 2021 TetraTREEdron Project click here
Maths on Toast is inviting families, schools and communities to come together in spirit and online this December to build and decorate a festive tree with a difference.
In the run up to Christmas (or Christ-maths as we like to call it!), we’re showing you how to make a TetraTREEdron to decorate your homes over the festive season.
After a tough 2020, we want you to use your TetraTREEdron to spread a message of hope so why not decorate your TetraTREEdron with reflections of the year, messages for the future or any decorative designs you like.
We’re encouraging families and schools to engage in this accessible creative maths project, suitable for all ages.
A festive tree, with a mathematical twist!
With this activity you will:
- Discover how to build a tetrahedron from a net
- Create a Tetratreedron from 4 tetrahedrons!
Materials you will need
- Tetrahedron Template (available to download above)
- Plain paper, pencil and ruler
- Scissors
- Glue
- Colouring pens, pencils or crayons
- Sellotape
- Further crafty decoration items (optional)
Watch the How To video
Your TetraTREEdron design could be:
- A message, a hope, a memory or a wish using pictures or a poem or written words (could be related to this unusual year)
- A Christmas tree design or a Christmas/New Year greeting
- A maths-related design
- A personal design that means something special to you and your family
Share a message of hope
We want families and schools to continue the community spirit felt by many during lockdown.
Build your Tetratreedrons, display them in your windows and watch (from a safe distance!) as your neighbours do so too. Bubbles at school can build larger trees with their messages of hope.
How your street, school or community can get involved
Families can display a small Sierpinski tree in their windows at home.School bubbles can display a large Sierpinski tree made by joining different children’s tetrahedrons together to form one large sculpture.
Everyone – families and schools – shares a picture with Maths on Toast (see below for how) for our community online gallery.
