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

Here's a simple, two-page explanation and chart I created to help students understand Distance-Rate-Time problems. These are for your classic, "two trains leave Chicago,"type questions covering: -two vehicles traveling towards each other, when do the meet? -two vehicles traveling in the same direction, when does one overtake the other? Students use this, along with their notes, to deconstruct the problems. Have fun! Hey you! Yes You! Need a better way to introduce equations? Here's a whole
