How does the September Slam contest work?

Fun and free

Between September 23rd – 29th, students simply answer math questions while playing Sumdog’s super fun online games.

Fair and adaptive

Questions are personalized and scores are based on accuracy, so everyone competes at their own level – and any class can win.

Prizes to be won

To motivate your students, there’s a trophy for the winning class, plus participation prizes, certificates and Sumdog coins.
