The CryptoClub Project is an afterschool program and website that provides motivating and fun activities for middle grade students to explore mathematics while learning cryptography. The CryptoClub Project was founded in 2005 due to the growing demand for math within STEM education and the difficulty in finding fun mathematics enrichment content. The Cryptoclub Project is funded by the National Science Foundation, Grant # 0840313 and #1311977. Prior funding was from NSF Grant # 0099220.
