Impact report: Sumdog proven to improve 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.


Giving children a six-month advantage

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 that regular Sumdog users made was almost double that of non-regular users.

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

To encourage extra practice, we have created a parent-version of the study for you to share.

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

Those children who have used Sumdog on a regular basis have made more progress than those who didn’t.
