Here are my recommended apps for this course. Some of them are nice for content related purposes. Some are just some of my favorite math or geometry related games. :)
I HIGHLY recommend getting Google Classroom, Drive and Calendar on your personal device. The others are up to your preference, depending on how much you use them (Docs, sheets, slides, and gmail).

"Strategy games and visuo-spatial puzzles might just seem an enjoyable way to pass the time, but they can also aid the development of creative problem-solving skills and help build resilience. Some puzzle games require players to experiment without any knowledge of the outcome, encouraging an explorative 'what happens if...?' mentality. Others require a more careful, strategical analysis of the situation and a 'what do I know, where do I need to get to?' approach."
