They love the games and are learning so much. Not only is it noticeable that they are doing better with their school work and their homework, but also they are picking up newly introduced topics quicker and that gives them more confidence in their abilities.

Automatically adapting to your child

As children play, they answer questions. Sumdog personalizes the questions for each one, and tracks their progress through the school standards.

Adaptive engine

Tailored for your child

While children choose what they play, our adaptive learning engine guides their learning.

Sumdog gets to know their individual strengths and weaknesses and ensures they always work on the right skill.
