I built this for students to practice arithmetic and strategy without it feeling like worksheets. No accounts needed, works on school Chromebooks. I’d appreciate teacher feedback on what would make it more useful.

For a few years, my dream was to be a software engineer. Then that dream was crushed.

Then, my dream was to be a mathematician. Now that dream is crushed.

What do I dream about now? Why bother if it's just going to be crushed? Why do they keep going for the things that I dream of instead of what's practical? Where are the AI managers, recruiters, execs, etc., why do they get to keep their dreams?

I’ve been building interactive math and physics experiences for SPECS AR glasses. Here are a few early examples: a hyperbolic paraboloid, solids of revolution, a double pendulum, and refraction (Snell’s law).

What interests me is the possibility of interacting directly with mathematical objects in 3D space, rather than just looking at diagrams or equations on a screen. Research suggests that gestures can support learning abstract mathematical concepts and generalizing to new problems (Goldin-Meadow et al., 2012; Seccia & Goldin-Meadow, 2024), so AR glasses with hand tracking feel like an especially compelling medium for this.

Any recommendations for mathematical concepts that would be a good fit?
How would you use something like this in your practice?
