It all adds up to a thorough education for New Rickstones Academy students.
Year 7 and 8 students spent a whole week focusing on numbers, whether the lesson was science, music or business studies.
This is the first time the school, in Conrad Road, Witham, has held a Numeracy Week, with plans to now hold one each term.
Each member of staff wore a maths question around their neck for students to work out during the event and the Happy Puzzle Company took along a selection of puzzles, games and challenges to get the students thinking.
Teachers from all subjects worked numeracy into their lessons to keep students on topic for the five days and tutor periods were spent on group maths activities.
Oli Bamigbele, who organised the event, said: “The students spent a lot of time working on shapes, building them and calculating their area, plus looking at the perimeter of 3D shapes and working out capacities.
“We also invited parents to come in to work with their children and the Happy Puzzle Company to give them an insight into what their children are working on and to improve communication between them.
“The Numeracy Week was about raising attainment in numeracy by showing the students numeracy is used in everything we do.”
Penny Tuffey, Year 8, said: “The week was really fun. It gave us a chance to think about puzzles and to try new things
