Disclaimer: there are many ways we can make this challenge higher leverage, involving academic discourse, naming strategies, connections to real-world contexts. I'm keeping it simple, folks. Just see what happens. And then comment and share!! Rules: In one of your upcoming math lessons, only use ONE … Continue reading #1ProblemChallenge
