The 99 Club is a mental-oral challenge which aims to raise standards in maths through encouraging pupils to improve their mental calculations when attempting quick-fire multiplication and division problems.
The idea is that with repeated practice, the scheme should result in increased speed and confidence when tackling mental maths problems without relying on written workings and methods.
Pupils begin at the 11 Club and work their way up. Children are given 5 minutes to complete the worksheets.
