Desmos can anonymize student names and freeze student screens
Sliders let students explore elements of problems, patterns, and graphs (for example, changing the m or b in y=mx + b)

Focus on real-world problem-solving in mathematics → mathematical modeling
"It's easy to enter into, but challenging to master and that, I think, is very satisfying in general."
