The 99 Club is a scheme used at Holy Trinity 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.

All pupils will begin at the 11 Club and work their way up, having one opportunity per week during one of their maths lessons to answer all calculations at their current level unaided and within the allotted time of five minutes. If all of the calculations are answered correctly, the child can move up to the next level!

The initial 11 Club involves eleven problems which involve doubling numbers up to ten ie. 5+5, 8+8. The 22 Club then adds eleven further questions involving repeated addition for numbers from one to ten ie. 3+3+3+3, 5+5+5+5+5, while the 33 Club begins to introduce times tables.

Division facts are added by the time a pupil reaches the 77 Club, and from the 88 Club onwards, pupils will be tackling a range of mixed multiplication and division problems. 

If you would like to have a go and practice improving your maths skills for the 99 club, here are all the sheets, which can be printed at home.
