The twenty-third JRMF Webinar took place on Saturday, September 5th, 2020 from 11 am until 12:30 pm. This virtual event was organized by Dr. Hector Rosario, Director of Outreach and Festivals of the Julia Robinson Mathematics Festival (JRMF). Participants were divided in several breakout sessions, depending on whether they were kids or adults. Dr. Jeanette Shakalli, Executive Director of FUNDAPROMAT, acted as the moderator in one of the breakout sessions for adults.
On this twenty-third Webinar, participants explored the interesting math activity called “Super Tic Tac Toe” which is used in Festivals all around the world. In this interactive activity, we explored a variation of the game Tic Tac Toe. In this variation of the traditional game, there are small tic-tac-toe boards inside each of the 9 spaces of the large tic-tac-toe board. The player who makes a 3-in-a-row in the large board, following certain simple rules that determine the relation between the smaller boards and the large board, will win the game.
