Welcome to the Parallel Maths Project!

Dr Simon Singh, author of the No. 1 bestseller Fermat’s Last Theorem and The Simpsons and Their Mathematical Secrets has created a set of weekly maths challenges – roughly 30 minutes of interesting, fun and challenging material that goes beyond school maths: mystery and history, activities and oddities, puzzles and problems.

  • Sign up and each week you will receive a Parallelogram, a weekly set of maths challenges.
  • It’s FREE to sign up and all the materials we offer are FREE.
  • Even without an account, you can get a taste of what we offer by just clicking on the Parallelograms on the left.
  • Teachers can create an account and set Parallelograms for their classes.
  • This site is aimed at 11- to 13-year-olds, but everyone is welcome.
  • We’ll be adding material for older and younger students soon.

Noun: Parallelogram Pronunciation: /ˌparəˈlɛləɡram/

Origin: late 16th century: from French parallélogramme, via late Latin from Greek parallēlogrammon, from parallēlos ‘alongside another’ + grammē ‘line’.

  1. a four-sided plane rectilinear figure with opposite sides parallel.
  2. a portmanteau word combining parallel and telegram. A message containing mischievous maths problems sent each week by the Parallel Project to bright young mathematicians.

The project was devised as an add-on for the Top-Top Set Project and is supported by the Good Thinking Society. All the materials are completely free.
