Department of Mathematics

Activities available on or off site

We have a variety of activities and workshops that are available to take out to local schools, colleges and other interested parties (if within a reasonable travel time of Brighton). These 'activities-to-go' are presented by a member of the Maths Department - either a researcher, research student, postgraduate or undergraduate student. All our activities are also available at the University of Sussex campus in Falmer, Brighton.

Please note:

  • All our activities are free.
  • We are flexible! If you have an idea for an activity not listed below, please get in touch and we will do our best to accommodate your class.
  • Multiple activities can be done during a single visit.
  • We may limit the number of times that we visit a particular school per academic year (depending on size), to enable us to visit as many schools as possible.
  • All our activities are suitable for Key Stage 4 and 5 (e.g. GCSE and AS/A-level/sixth-form) students.
  • Please give us as much notice as possible when requesting an activity to ensure that we have enough staff available on the day. This is especially important for larger events (more than 25 students) which will require more than one member of the Department to assist.


Available activities and workshops include (scroll down for full details):

  • The Great Race
  • The Maths of card tricks
  • The Monty Hall game and problem
  • Geometric shapes
  • Interactive maths puzzles
  • How many? Estimating numbers


The Great Race

1 hour

Students will learn about probability and relative frequency in the context of 'The Great Race' - a horse race where the horses move forward depending on the outcome of a dice roll. Students will decide which horses are more likely to win, which horses cannot win, and why. The activity is suitable for KS3 students, either as an introduction to probability, or to reinforce concepts already learned

The Maths of card tricks

1 hour

There are lots of fun mathematics behind card tricks, and in this workshop students get to discover them first hand!

The Monty Hall game and problem

1 hour

The Monty Hall problem originates from a TV game show, where contestants have to guess which door a new car is hidden behind and avoid choosing the two doors containing worthless prizes. After the contestant chooses a door, one of the booby prizes is revealed, and the contestant is given the opportunity to select the other door instead. But should they stick with their original choice, or swap? Fortunately, mathematics can advise us on the best course of action! In this practical, students get to play the game and then study the maths behind the puzzle.

Geometric shapes

1 hour

Geometry is an important branch of mathematics, and in this workshop students get to experience the surprising results of geometry first hand.

Interactive maths puzzles

1 hour

We have a wide variety of maths puzzles available to try out on your students!

How many? Estimating numbers

30 minutes

There are numbers mathematical ways to estimate populations, whether it is of how many aircraft are in the sky at any one time, to the number of tigers left in the wild. Here, we introduce several methods and get students to play out some examples. For example, the Capture-Recapture method can be used for estimating population sizes, and students get to try it out for themselves using ping pong balls in a container!
