Mathigon is an online interactive textbook for mathematics, which we’ve written about here before. They’ve just launched updated versions of the phone/tablet app version of their site, including new features and an offline mode.

Creator Philipp Legner says:

Our goal is to make learning as interactive and engaging as possible, using games, simulations, virtual manipulatives, puzzles, and real-life applications. Earlier this week, we published a big update to our mobile apps for Android and iOS, which you can install here.

Just like our website, they are completely free to use and contain the same content – but, once installed, they work completely offline. We store your progress locally, and then sync it with our server whenever you are online. Hopefully, this will make our courses more accessible to students without a stable internet connection.

We have also added two of our most popular activities: Factris, a Tetris-like game that teaches about divisibility, and Polypad, a collection of virtual manipulaties. Just in the last week, users have created over 1.3 million individual Polypad tiles! And we have added many new biographies and artefacts to our Timeline of Mathematics, with a particular focus on diversity.

We can highly recommend Mathigon – it’s a great resource, and as well as working through the activities in order, you can dip in and out, use individual sections to complement teaching/learning, or just use the manipulatives and interactives on their own.
