- Sent by the class teacher to x-math@eudactica.com between 1 and 31 December 2025;
- Accompanied by the school name, class identification, and the names of the participating pupils.

Within 48 hours of submission, the organisation will confirm receipt of the video.
If no confirmation is received, the teacher should contact Eudactica.

𝗜𝗺𝗮𝗴𝗲 𝗥𝗶𝗴𝗵𝘁𝘀
To publish a video featuring students, written consent from parents or legal guardians is required. If such consent cannot be obtained, teachers may submit audio only, accompanied by an image of the school or its logo; or record a video without individual student identification. All eligible submissions — whether video or audio-only — will be included in the public voting.

Participation in the X-MATH Challenge implies full acceptance of these rules. Eudactica reserves the right to exclude entries that fail to meet the requirements or contain inappropriate content.
