Getting Started

We’re signed up for the Count on Us Secondary Challenge and our students can’t wait to get started using the maths activities.

What next? See below for a fantastic range of resources to support you in setting up clubs and to use in class.

Now that you have signed up for the Count on Us Secondary Challenge, you will want to get your students started. At the training in January, we will take you through the details of the tournament activities.

Count on Us is not just for your team of 5 students! It is for a group of 60 or more students in your school to develop their mathematics through puzzling, mathematical fluency and problem-solving.


Here we have links to the programme handbooks in PDF format for you to download.

The Guidance for Schools contains details of the whole programme including support on how to extend the activities to all of your key stage 3 students and across the school.

The Student Workbook contains details of the tournament activities and a large collection of activities designed to help students with their catch-up work and add to their knowledge and skills in key stage 3 mathematics.

The Training Slideshow and Training Video are from our live, virtual training sessions. These are held towards the start of the calendar year, with each school’s teaching staff invited to attend. The slideshow from the sessions is available to download here, alongside a video recording of one of the training sessions.

You should have been invited to one of our training sessions. Please contact if you haven’t received an invitation email.

There are four rounds in the Count On Us Secondary Challenge tournament.

In order, they are Hedgehog (it’s new!), GridLines Geometry (a card game), The 24 Game (a number game) and Algebraic Problem Solving (a London-themed challenge). Here are activities to introduce you and your students to these rounds. You will need to read the rules for GridLines Geometry in order to do the activities.



This is an excellent set of videos taken with students using the activities in a group. Take time to work through these videos carefully. They show in detail how each round works in the tournament. We would encourage you to share them with your team members and any other interested students.


Please note: from 2022, the fourth round will not require code-breaking.


Here are a set of short activities that you can use to introduce the rounds to your students, in addition to the Student Workbook.

 4 – Algebraic Problem Solving

This round changes at every event, so you cannot prepare for the exact activity. It is always based on a story scenario and involve problems to solve which will be a surprise.

However, teams will have to be able to do all the algebra that is required at key stage 3. A full list is in the teacher’s guide.
