Develop your students’ math and spelling skills

At Sumdog we’re committed to delivering the most engaging personalized practice tool for math and spelling. We use direct feedback from teachers to drive our product development, and we carry out regular educational research to evidence the difference we’ve helped them make.

We’d love you to join us. By combining an appealing gamified experience for students with a robust set of tools and reports for teachers, we can help you reinforce the teaching you do in class, build pupil confidence, and find and fill gaps in student knowledge.

Students who usually struggle with mathematics become motivated.

I was also able to differentiate through the skills-based challenges and assign different ones to students who struggle with prior skills.

You control the learning

Our intervention tools will help you identify students who might be struggling, then set them tasks and challenges that support them in their learning. And since Sumdog can be played at home or at school, that learning can take place anytime, anywhere. We even provide you with resources to engage parents as part of the Sumdog journey.
