Algebra 1 practice, unit by unit

Algebra 1 is where the rules of the game are set: how to keep an equation balanced, what a function is, why a line has a slope. If any of it feels shaky, that's worth fixing now. It all comes back in Algebra 2, AP Precalculus and AP Calculus, usually with less time to think.
