Unit rates are all around us: price per pound, servings per day, miles per hour. In this video, watch how different graphs display proportions as linear functions. Have your learners organize the data into a chart to calculate the unit rate. The video uses the multiplicative inverse to find the unit rate, but some learners may prefer division.
