Students find the constant from a pair of values, fill in the missing value in a proportion, work out unit rates and unit prices, and use the equation y = kx in both directions. Perfect for math centers, small groups, warm ups, homework, spiral review, test prep, intervention, early finishers, substitute plans and homeschool. Completely no prep - just print and go.\u003c\/p\u003e\n\u003cp\u003eEvery case is set at a schools sports carnival, one sport to a page: the goal nets gone off their posts before the first match, ten lanes reset wrong before the closing frame.
