The COBIS / Mangahigh Maths Challenge is a free, online competition for 5-16 year olds designed to engage students with maths through a games-based learning approach. Using Mangahigh, students complete maths activities, which teachers may personalise to support students’ learning, to score individual points, which in turn contributes to their school's tally. Students can access their activities at home or in school so it can be used for homework, revision, or a fun task!
