Welcome to Sumdog!

Our mission is to narrow the attainment gap by helping every child reach their full potential. in 2010, our founder, Andrew Hall, set out to create an engaging platform that would support children from all backgrounds with their math practice and create an even playing field amongst learners. 

Sumdog is now used by missions of children worldwide. Providing numeracy and spelling practice for children aged 5-14, it adapts to each individual using engaging game-based learning to motivate and build confidence.

Working at Sumdog

Built on values

Building value in our business isn't about the bottom line, it's about what drives us to do what we do. Sumdog is guided by core values that have been designed in partnership with our team.

Driven by our mission

 to narrow the attainment gap by helping every child reach their full potential.

In tune with teachers, parents and children

to understand the needs of teachers, parents and children. Our solutions are born from these needs.

Always learning

to ensure that our people are developed alongside our products. We experiment our way to success and value continuous personal development.

Decisive

We make decisions at pace because the greatest risk is standing still. While making decisions, we encourage constructive feedback. We don't fear failure because we work in a supportive environment.

Collaborative

Together, we have the power to solve seemingly unsolvable problems. We do it all the time.

Inclusive

We aim to serve children from all backgrounds. To do that. we seek to work within a diverse team who embrace differences.

Closing the gap

Governments around the world recognise the attainment gap as a serious problem. We believe that every child has the potential to achieve, but some are more confident than others. We've designed Sumdog to engage all pupils - especially those who haven't found learning easy. Our adaptive learning engine targets questions to each individual, letting everyone find success. While they work, Sumdog's educator tools identify areas for their teachers to address, and reports on progress. 

Adaptive mastery learning

Sumdog helps teachers to deliver mastery learning. Our learning engine progresses pupils automatically through the curriculum. While the class works, detailed reports help teachers pinpoint the areas the should address. By motivating pupils, we build them into confident learners, and help make sure there are no gaps in their learning.
