Join our summer contests


Sumdog’s free online mathematics contests are a fun way to motivate your students.

To take part, they just play Sumdog’s online games, any time during the contest week. Scores are based on accuracy, and the questions adapt to each student’s level – so everyone has an even chance of winning.

Summer rewards for students

As a reward for taking part, each student will receive a summer-themed item for their Sumdog House.

…and for teachers as well!

A reward for teachers, too: you can request a special report showing how hard your students have worked during the contest.

You’ll see information about the skills each student has completed, and the efforts they’ve put in. Take part to find out more!
