There are 7 levels of Ace Adders (example sheets can be found under curriculum-maths-ace adders) that include simple addition and subtract questions. There are between 10 & 16 questions on a sheet and the children have 200 seconds to answer as many of them as they can. If they get full marks for two weeks in a row then they move up to the next level. When the children have completed all of their ace adder levels then they will be presented with a green ace adder star badge.
(Please keep this badge safe as it will need to be traded in for the next badge or you can pay £1 to keep your previous badge as well as the new one)
