The Count on Us Primary Challenge is a maths tournament for Year 4 and 5 pupils involving over 100 schools from across London. The tournament focuses on shape puzzles, number games and code breaking challenges to help develop children’s confidence, problem solving skills and most importantly, their enjoyment of maths.

After running activities in school, schools select a team of their top mathematicians to represent them in the Regional Heats. Qualifying teams are then invited to City Hall for the final events in the summer term.

The Count on Us Primary Challenge is split into three main categories;

Round 1    Shape – A team activity based on tangrams and pentominoes
Round 2    24® Game – Mental arithmetic activity using 24® Game cards
Round 3    Codebreaking – Using the Caesar cipher to decode messages and solve a problem

Have a go at the 24® Game:

The 24® Game consists of a pack of cards. Each card has four numbers printed on it. All four numbers on the card must be used once and once only to make 24 using the four basic arithmetic operations; +, -, × and ÷

For example:


4 – 2 = 2

4 x 3 = 12

12 x 2 = 24

Have a go at these cards and see how you get on. A 10-year-old can complete card 1 (click to download) in 15 seconds and card 2 (click to download) in 30 seconds. Can you beat a 10-year-old?
