D.Tech Problem of the Day Challenge

The D.Tech Math Club hosts an online Problems of the Day Challenge, d.PotD, for middle school students in the week before DTMT. Over five days, students receive three problems each day, including one proof-based question, and have two hours to solve them. Spanning multiple subjects, including algebra, geometry, number theory, and combinatorics, the problems are designed to challenge students' reasoning skills and expose them to a broad range of mathematical ideas. This serves as a lead-up to our main competition and promotes creative problem-solving and proof-based mathematical communication skills.

This competition is open to all middle school students across the US, and prizes will be distributed online. Winners will also receive name recognition at DTMT. For more information regarding d.PotD, including how to sign up, how to access our online portal, and the event schedule, will be published closer to the competition date. Stay tuned for more!
