About Sumdog Reading

Sumdog Reading

Sumdog Reading helps students aged 6-11 practice their grammar and vocabulary using our fun and engaging 2D and 3D games.

Sumdog Reading has thousands of questions on grammar, punctuation and spelling, aligned to key curriculum and standards.

Typical questions involve students being presented with an incomplete sentence, and asked to fill in the blank from a choice of options.


Sumdog Reading covers a range of skills, from capital letters and reading short words, to antonyms and synonyms, to relative pronouns.

Teachers can modify the order of skills to match their lesson plan, and set assessments and challenges to check learning and identify gaps.


With Sumdog Reading teachers have access to powerful reporting that shows each child's progression through the skills, and can identify any gaps in learning.

Students who usually struggle with math become motivated.

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