I love working with students and introducing them to that. The main type of things I do, I like to use games. So I will study things like guessing games by thinking of a number from one to a million. And you can ask me yes or no questions about it. Can you figure out my number in fewer guesses? Right? What's the smallest number of guesses you need? What if I'm allowed to lie sometimes? If I'm thinking of two numbers and I only tell you how many of mine fit your question? All of these variations are they're about counting. They're about how numbers work and how they're arranged. It's almost naturally motivated. Because people care already
