The Julia Robinson Mathematics Festival, which held its first event in 2007, was named after a famous mathematician. Though the festival was partially sidelined due to Covid a couple of years ago, it continued with virtual events, and it looks like it has some upcoming activities. If you are unable to attend in person, though, you can still participate by playing one of the many online games, or even downloading one of the free, printable booklets. The games include some classics, like River Crossings, and Tower of Hanoi, but there are plenty of others that will likely be new to you and your students. One very helpful feature you will find is that the instructions to each game are on Google Slide presentations, with links to the online game, and an option for Spanish instructions.
I’ll be adding this link to two of my collections: Brainteasers and Puzzles and Math Sites That Won’t Make You Fall Asleep. Got advanced learners? This would be great for them! Early finishers? Students with math anxiety who need to see it can be fun? A little extra time at the end of class or a much-needed break from test prep? These are all good occasions to check out the JRMF site!
