# Resources

## The Twelve Days of Christmas

This set of resources is all about the song 'The Twelve Days of Christmas'. Work out your own Christmas Price Index (the cost of all the gifts in the song) as calculated by the PNC every year, create a formula for how many gifts are received in the song by the nth day and even make an extra festive Christmas Price Index chart.

## Mirror Pillar activities

Think Maths team members Matt and Katie have created a maths project that will take place from October 2018 - they've made a 2m tall cylinder out of mirror steel, and will be using it to create anamorphic images. Anamorphic images have been distorted, so that they only look correct when viewed from one exact position.

## The Utilities Puzzle

Have you met the Utilities Puzzle? A puzzle that cannot be solved on flat surface but can be solved on the surface of a mug! Introduce your students to this puzzle and other areas of graph theory with this set of 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

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