When my students were working with solving first level equations, I started to make these problems to help them see a more concrete model next to the symbolic algebra. Eventually, it became this: A unit that moves students from the concrete to the abstract in careful steps. You get: Part 1: Basic equations to variables on both sides Part 2: The Distributive Property Part 3: Substitution property for systems I tended to avoid dealing with negative numbers where I could, as that comes in at

So, at some point or another, we've all learned how to divide a fraction. However, many of us barely remember it, while some might remember that it has something to do with "flip & multiply." What if we focused on why we do what we do when we divide fractions? That's what this video is meant to do. Suitable for kids & adults, it shows you not only how to divide fractions, but what's really going on when we perform the algorithm. Enjoy!
