Event description

The best mathematicians make the best codebreakers. They have logical minds, they can stick at a task, see patterns and follow algorithms.

In this hands-on workshop, Jenny Sharp will explore codes and ciphers from the last 2000 years. Students will learn how to create codes and ciphers to send secret messages and how they can be broken.

About the speaker

Jenny Sharp works at Plymouth University. As well as teaching on the undergraduate programmes, she runs a very busy Mathematics Enrichment Programme for Schools throughout Devon and Cornwall, running workshops for pupils and their teachers from Year 5 through to Year 10.

Jenny is a regular Ri Mathematics Masterclass speaker and has delivered Masterclasses on a wide range of topics.

Please note

Please note, this workshop is strictly for 7–9 year-olds. There will be a short break during the workshop and a drink and a small snack will be provided. Students should bring their own snack if they have any allergies.

Discounted tickets are available to Ri Members. Find out more about how to join.

Mathematics Summer School workshops are based on Ri Masterclasses. Students who have attended a Masterclass series which included a session on a similar topic may have already seen some of the content in this workshop. Please contact us on with any questions.

Refunds can only be issued for tickets cancelled at least two weeks (14 calendar days) in advance of the event date. Please note that this supersedes our normal event terms and conditions.


Workshops are on the first floor of our building, for which there is step-free access from the street via lift.

The closest underground station is Green Park, which is step-free.

Seating is usually unreserved for our events. If you and your group require seating reservations, or if you have any other questions, please do let us know by email and we’ll be more than happy to help. Email:
