National Numeracy is an independent charity (registered no. 1145669 in England and Wales) based in Lewes, UK, that promotes the importance of numeracy and "everyday maths". The charity was founded in 2012; its chair is Perdita Fraser and vice chair Andy Haldane. Its current chief executive is Sam Sims, who replaced Mike Ellicock in 2020. National Numeracy has been critical of the UK mathematics curriculum, claiming that it is flawed and requires radical improvement to ensure that everyone leaves compulsory education with essential numeracy skills.
