De Wiskunnend Wiske wedstrijd ontstond vijf jaar geleden aan de faculteit Wetenschappen en Bio-ingenieurswetenschappen. Ongeveer 2000 wiskundeknobbels uit het vijfde en zesde jaar secundair onderwijs buigen zich jaarlijks over een aantal intrigerende wiskundige opdrachten. De wedstrijd won in 2014 de KVAB jaarprijs wetenschapscommunicatie.
