About this collection

There are 23 designs to choose from. Times Table Champion and Human Calculator are for the ones who actually enjoy maths, Maths Arcade and Maths Speedrun borrow a bit of gaming style, and I Came For The Pi is the joke the teachers will appreciate. My Favourite Number 7 covers the classic brief of wearing a number to school. Every design is also available as a hoodie if the day falls on a cold week.

T-shirts are £4.99 and come in Black, White, Red, Green, Blue and Heather Grey, in unisex sizes 3-4, 5-6, 7-8, 9-11 and 12-13 years. The hoodie is £9.99. Each one is printed to order in the UK, so it is worth ordering a week or so ahead.
