The augmented reality resource that I might be able to use in my classroom is Aurasma. It is a free app that allows you to create your own AR experience. You could use this to create an AR word wall, diagram, book report, or worksheet. Check it out. It seems pretty neat.
The second session that I attended was about using the concrete - representational - abstract (CRA) in middle school geometry. We explored the volume of prisms.
I presented during the last session. Here are my resources from the day.
Looking forward to another day of learning at STEMathon day 2!
