Bring North Star to your students
Six online math contests a year for grades JK–8, plus daily practice — the successor to the Caribou Mathematics Contest, now run by a Canadian not-for-profit.
What it costs
No school ever pays more than CA$640, however many students take part. This is one annual payment covering the whole season — there is no per-contest fee.
What it works out to
| Students | Cost |
|---|---|
| 5 students | CA$75 |
| 20 students | CA$300 |
| 43 students | CA$640 (capped) |
There is a minimum charge of CA$75 per school, so up to 5 students the cost is the same.
The CA$640 cap takes effect at around 43 students.

Frequently asked questions
Can we pay by invoice or purchase order?+
Yes. Many schools can't use a credit card, and we can invoice your board or process a purchase order — just say so when you get in touch.
What if we're not sure how many students yet?+
That's fine — register with an estimate. You can add or remove students up until each contest date, and your final cost is based on actual participants.
Do students need individual accounts, and what data do you collect?+
Schools may use proxy identifiers instead of real names if preferred. Contest results and rankings are kept so students and coordinators can look up historical results, and how we handle data is set out in full in our privacy policy. Read the privacy policy
What happens after the free round if we don't continue?+
Nothing further is owed and nothing carries over automatically. The free round carries no commitment — you decide afterwards whether to continue with the rest of the season.
Do you work with US schools?+
Yes. US schools are billed in US dollars, at the per-student rate and cap shown above when you switch the currency toggle.
Can parents register individually instead?+
Yes — parents can register their own children without going through a school. See the parent pricing page for details.
