So, what to craft for that maths geek special someone … may we suggest polyhedral dice pillows?
These squashy beauties are from ¡The Anticraft!. There are full instructions and helpful diagrams on the website. These would also be a great classroom resource.
Warning: the folks at Anticraft are honest in their language, so don’t click if you prefer subtler prose.

Santa’s secret is that he can get your class to revise harder topics – without them realising!
Equipment
- Download the worksheet (optional)
- Paper & pen
- Calculator
- Paper chains (optional)
Activity
Paper chains are made from equally sized strips of paper. Each loop is made from a strip of paper, which has one end glued to the other.
Question 1
How many 3cm by 18cm strips of paper can you cut from a sheet of A4 paper? Remember, each strip is made from one complete piece of paper.
Question 2
If each strip has an overlap of 1cm, what is the circumference of the loop made? What is the diameter?
Question 3
When two loops are attached there is an overlap of 0.5cm. How long would a chain of 12 loops be?
Hint: two loops with diameter 4cm would have a combined length of (4+4-0.5)cm = 7.5cm.
Question 4
A room has dimensions 5m by 7m. How far is it diagonally across the room?
Question 5
How many loops would a paper chain have if it reached diagonally across the room?
Extension
To make the chain hang in U shape, rather than stretching flat across the ceiling, 5 extra loops are added per whole metre of chain. How long would the chain diagonally across the room be? How many loops?
Challenge
How many sheets of paper would be required to make enough paper chain to hang in a U shape joining every corner of the room?

Why is ‘reality’ TV so popular, when we know so much of it is as unreal as it gets?
Whilst you ponder this, consider your eighth gift from the Sandpit – some paparazzi fun!
