An intuitive, data-rich maths and spelling platform that saves teachers time while keeping children motivated and engaged…
There are some platforms that look impressive on paper but take time to get your head around. Sumdog is not one of them.
From the moment you log in, it feels like a platform designed by people who understand how schools actually work. It is intuitive, clear, and genuinely makes a teacher’s life easier, without compromising on quality or rigour.
The set-up process is refreshingly straightforward. Whether you are adding a new class or joining an existing school account, everything makes sense and mirrors systems teachers are already familiar with.
New users are guided through a short walkthrough that clearly explains the key features, which is especially helpful if time is tight. Once you are in, the dashboard gives you an immediate overview of what is happening across your classes, making it easy to switch between groups, year levels, or roles such as subject lead or senior leader.
The real strength of Sumdog lies in its maths provision. The platform is aligned to the White Rose Maths scheme of learning, which means it complements classroom teaching rather than pulling in a different direction.
The diagnostic assessments are particularly powerful. Teachers can see exactly where each child is working, both at an individual level and across the class. You can quickly identify who is working below, at, or above expectations, and which specific areas need attention.
This makes planning interventions, booster groups, or next lessons far more targeted and purposeful.

Sumdog’s maths fluency tools build on this by supporting pupils with core number skills through regular, adaptive practice. The questions adjust based on pupil responses, helping children consolidate foundational knowledge before moving on.
Setting even short, regular practice gives teachers meaningful insights that feed directly into planning next steps. The reporting is clear and easy to interpret, allowing you to spot trends, gaps, or successes without wading through unnecessary data.
What children experience, however, feels very different from assessment. The games are engaging, colourful and motivating, which means pupils want to practise.
This is where Sumdog really succeeds. It manages to combine robust assessment and curriculum alignment with genuine enjoyment. For many children, it feels like play, while for teachers it delivers precise information.
Alongside its maths tools, Sumdog also includes spelling and grammar activities that are just as thorough and well thought through. The platform provides diagnostic assessment and clear feedback, supporting grammar and spelling development while helping to highlight gaps and inform next steps.
Used thoughtfully, this helps build a more rounded picture of each learner.
Overall, Sumdog is one of those platforms that earns its place in the classroom. It supports teaching, sharpens assessment, and keeps children engaged, all while saving teachers time.
