The math advent calendar invites secondary school pupils to discover the beauty and power of math beyond the subjects covered in school.
From December 1 to December 24, a box is 'opened' daily on the Mathekalender (math calendar). Behind each box a math problem appears with ten possible answers. These tasks are challenging and comparable to the level of the final of the Dutch Mathematical Olympiad.
