A proven approach to accelerate and improve math fluency

Mathematical fluency gives children the ability to recall and apply knowledge rapidly and accurately. It is a crucial building block and the foundation for later learning. Impact studies are central to Sumdog’s mission and help to guide our pedagogy and refine the program. Read our recent study published in the Impact Journal of the Chartered College of Teaching or download a summary below.

Sumdog almost doubles children’s fluency progress

This study set out to investigate whether using Sumdog on a regular basis has an impact on students’ mathematical fluency. The findings revealed that the progress made by regular Sumdog users was almost double that of non-regular users giving them a 6 month advantage over their peers.

The Education Endowment Foundation (EEF) describes an effect size of this magnitude as “high impact”; equivalent to a six-month advantage.

Sumdog is available for ALL schools to try for FREE. See for yourself the impact Sumdog could have in your school.

We’ve created a parent-version of the study for you to send home.

It explains the results of the study and how families can support children’s learning at home.

You can set challenges to be completed in class or for homework.

Support personalised learning

Track individual progress against the standards.


Save valuable teaching time

Use custom assessments to quickly identify gaps so you can target intervention, and get results immediately with our auto-marking feature.

“I’d recommend Sumdog as a fun way to present mathematics to children without them even realising that they are practising their skills! Those children who have used Sumdog on a regular basis have made more progress than those who didn’t.”
