I can solve real world problems involving surface area of cubes.

I can draw a model for a proportional relationship.

I can compute unit rate.

My Humble Opinion
Skills in this standard

Compute unit rates measured in like units

Compute unit rates measured in unlike units.

Prerequisite skills

Simplify fractions

Divide fractions

Work with complex fractions

Convert units of measurement within the same system

Convert units of measurement from one system to another

This standard does not seem to add content to the previous course of study for 7th grade. The example seems to be more rigorous than the questions asked in previous ARMT item specs.

## 7-RP1

## Compute unit rates associated with ratios of fractions, including ratios of lengths, areas, and other quantities measured in like or different units.
