: If you're new to Sumdog, you will need to request a 30-day trial to take part in an upcoming Sumdog contest.

If you have an existing free Sumdog account, you will be able to take part in upcoming contests until April 2023. After this, you will need to either purchase a Sumdog subscription or request a trial.
: Sumdog is aimed at children ages 5 - 14.
: Prior to the start of the contest, we would recommend that you have your pupils log in to Sumdog so they can complete their diagnostic test. This places them at their ability level.

The questions asked during the contest will be based on their diagnostic test score.
: To make our contest fair, there is a minimum of 5 pupils per class. The maximum class size is 35.
: Once the contest has started, your pupils will be able to see the name of the contest in their Activity Panel. Below that, they will be able to view how many questions they have left to answer in the contest.

Only the questions answered as part of the contest will count towards the contest score. If your pupils are still in the process of doing their diagnostic test, these answers won't count.

If your pupils aren't able to see the contest name in their Activity Panel, do make sure that they have completed their diagnostic test and that they have not selected another activity. Check that the correct class has been entered.
: We do not have a time limit for our contests. Pupils can log in any time during the contest period to answer questions.

We know that not all pupils have access to devices outside of school so, to make the contest fair, we do have a 1000 question limit. This means that once a pupil has answered 1000 questions in the contest, any questions after that will not count towards their contest score.

On the contest task, pupils will be able to see a 'Questions remaining' box, showing them how many questions they have left.
: Our Sumdog maths contests run for a week starting on Friday at 8am (local time) and end on the following Thursday at 8pm (local time).

During the contest period, pupils can log in at any time to answer the questions, either in school or at home).
: The individual pupil scores are calculated based on correct answers. Each correct answer will equal 1 contest point.

Class scored are calculated on a class average. This is done to make it fair for both larger and smaller classes.

Scores on the leaderboards are not final until the Friday after the contest ends.
: You will be able to view your class scores on the contest leaderboard. You can log into your teacher account and view the leaderboard here.

Select the contest you would like to view from the list and click 'classes' under the leaderboard heading.

Scores on the leaderboards are not final until the Friday after the contest ends.
: All pupils who have answered 100 questions will receive a virtual item for their Sumdog house. This item will be delivered automatically as a gift to their account.

Each pupil in the winning class will receive virtual Sumdog coins to spend on items for their house or garden.

The top 10 pupils overall will receive a printable certificate.

The top class each day will receive a printable daily winner certificate (a class can only be the Daily Winner once during the contest).
