Summer Celebration: Mathematical Surprises

Virtual show for Year 7 – 9, all attainment levelswith Zoe Griffiths.

Book to watch a recorded version of this show at any time this summer term.

(PLEASE NOTE: The 2026 Live Summer Celebration shows have been cancelled, so you can only book to watch a recording of last year.)

Join Zoe Griffiths for this summer celebration of maths, that explores surprising maths in an interactive and engaging way. With the help of the audience, we experience a live magic trick, conduct a live audience experiment and join in with a curious activity. Surprising maths is hidden in surprising places!

Topics: We are introduced to the strange world of spherical geometry via an activity, we explore the number patterns in bar codes via a magic trick, and we explore the probability of the Birthday Paradox via a large, live audience experiment.

More Details

Who is this show suitable for?

This is an enrichment show, meaning the majority of the material is adjacent to, but separate from, the curriculum. There is not much curriculum knowledge assumed.

To give you a sense of the prior maths assumed, Zoe will:
-Reference that the ‘the sum of the angles in a triangle is 180 degrees’ (but if your students don’t know this, it’s not a problem, as Zoe tells them this fact anyway),
-Use some simple terms without definition, including: ’90 degree angle’, ‘multiple’, ‘sum’, ‘triangle’,
-Assume an understanding of the very basic concept of probability (students are not required to be able to find numerical probabilities).

Zoe will challenge students at one point to count how many pairs can be made from a group of people, and will then explain the solution. All students can have a go. Some students will have more success than others, and some students will follow the solution more easily than others, but the maths that will be used is not anything students won’t have met (it’s counting and adding, or multiplying and dividing).

Although only basic knowledge is required, that doesn’t mean the show is not suitable for more able students. The show is very suitable for more able students – they will be seeing maths used in unusual and engaging contexts – it will enthuse and excite them about maths.

Teacher involvement:

Although the tasks are suitable for all-ability Year 7 – 9, and all the explanation and clear instructions are given to the students by Zoe, the nature of a virtual session means it’s realistic that teachers will need to follow the session as well so they can prompt/support some students with activities if needed.

Equipment: Students will need scrap paper, and a pen.

Print document: There is one document for the show that it would be helpful for the students to have one copy of each. You will be emailed the file. It can be printed in b/w or colour. Or you can choose not to print at all (students can still take part without the print out, but the print out would be easier for them).

Content: Please note there is an overlap between Adventures with Shape (May 2026) and this show. The arm trick and spherical geometry section is the same.

There is a tiny overlap in content between Merry Mathsmas (Zoe’s Christmas virtual event) and this virtual event. In both sessions we count how many ways there are to pair things up – in Merry Mathsmas this maths was used in connection to the lottery, in this show the maths is used to explore a different problem.
