# Resources

## Psychic Pets

Across the world pets are making predictions about the outcome of World Cup 2018 games with Matt Parker's Psychic Pets project (video below). You can join in and register your pet!

These worksheets help explore the maths behind the Psychic Pets project. Curriculum topics covered include probability and combinations and permutations.

## Shapes of Constant Width

Did you know a circle is not the only shape that maintains the same width as you rotate it? There are other, lesser known, 'shapes of constant width'. In this set of resources students can explore what it means for a shape to have 'constant width', learn how to construct shapes of constant width using a pair of compasses and discover some real life shapes of constant width.

## Maths Fest Puzzles!

Puzzles made by the Think Maths team for Maths Fest 2018. Includes a hints sheet and a solutions sheet. We hope they come in handy in the classroom. Enjoy!

## Three-sided Coin Activity

Help us estimate the dimensions of a fair cylindrical three-sided coin, by taking part in our experiment!

## Snowflake or Snow-fake?

These resources are centred around students making snowflakes with 6-fold symmetry (real snowflakes always have 6-fold symmetry!) and not 'snow-fakes' - those with 8-fold symmetry, for example.

## Origami Tangram

With these resources students can fold their own Origami Tangram pieces (or cut them out) and then investigate the properties of the shapes of the pieces, before solving some Tangram puzzles with them.

## Pi Approximation Using Factors Activities

In this set of activities students approximate Pi by rolling dice and spotting factors between pairs of numbers.

## Tetrahedron in a cube activity

Can you fit the tetrahedron in the cube? This nice little puzzle activity challenges 3D spatial awareness and thinking skills, as well as building nets and reinforcing knowledge of some simple polyhedra.

## Make a dodecahedron from A4 paper!

Did you know it's possible to build a dodecahedron using only 12 sheets of A4 paper?

## Hinged Dissection Activity

Thanks to the Wallace-Bolyai-Gerwien Theorem we know that any polygon can be dissected into pieces and rearranged to match any other polygon of the same area.
