Sumdog Maths


Personalised maths practice and low-stakes assessments that pupils love

Product Type
Age Range

Sumdog is an online practice tool which uses game-based learning to build maths fluency. A recent study found that using Sumdog for 30 minutes a week almost doubled children’s fluency progress. It encourages regular practice, high accuracy and quick mental maths, using positive reinforcement to ensure pupils stay on task, learn more effectively, and are invested in their own success.

It is free to join, with optional subscriptions unlocking additional functionality and extra games. Free accounts give access to 6 of the most popular learning games and a new diagnostic tool that helps to identify areas for catch up this term. After completing the diagnostic, the adaptive learning engine works to ensure pupils are working at appropriate level, progressing them through the national curriculum for KS1-3.

Identify areas for catch up this term

The new maths diagnostic tool gives you a snapshot of children’s learning but in a stress-free environment.  It not only provides you with an easy-to-read, stranded report, aligned to your curriculum, but it also sets the questions for each child on Sumdog, ensuring pupils are answering personalised questions tailored to their needs to keep them motivated and ready to learn.

Prepare for the MTC with Sumdog Tables

Encourage your pupils to build their tables fluency through a mixture of child-directed play, tables challenges and an Multiplication Times Table Check practice test.
