Welcome to Sumdog!
Back in 2010, our founder Andrew Hall set out to build something simple but powerful: a learning platform that would help every child, whatever their background, feel confident with maths and level the playing field in the classroom.
Today, Sumdog supports millions of children around the world. Designed for ages 5–14, it provides adaptive maths and spelling practice that meets each child at their own level. Using engaging game-based learning, Sumdog keeps pupils motivated, helps them build core skills, and grows their confidence over time.
