Ratios and Proportional Relationships 7.RP.A.1

1. Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction ½/¼ miles per hour, equivalently 2 miles per hour.

If it ain't broke, don't fix it, right? That's pretty much the mantra in this standard, which takes a close look at addition and subtraction of rational numbers. Lucky for your students, a lot of the same rules for integers will work here.

With a few minor tweaks, students will be able to use what they already know about addition and subtraction and apply it to rational numbers—i.e., anything that can be expressed as a fraction. They'll also be looking at visual, geometric interpretations of addition/subtraction, positive/negative numbers, and additive inverses. It's number line time, y'all.
