Upon publishing your Instructable you'll see checkboxes for open contests. Select Made with Math Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.
