This is a video lesson explaining ratios, rates and unit rates, with problems to test what you've learned. The video contains several example problems that are worked through. This would be good to use at an independent computer station during math... rotations. There is also a link for printed out problems. (10:35)

Two besotted rulers must embrace proportional units in order to complete a bridge to unite their lands. It takes mathematical reasoning to deduce the problem, and solution, when engineers from Queentopia and Kingopolis try to build a bridge that meet...s in the middle of the river. This is a great resource to help middle school students master these important mathematical concepts. (6:03)

Continue exploring rational numbers, working with an area model for
multiplication and division with fractions, and examining operations
with decimals. Explore percents and the relationships among
representations using fractions, decimals, and per...cents. Examine
benchmarks for understanding percents, especially percents less than 10
and greater than 100. Consider ways to use an elastic model, an area
model, and other models to discuss percents. Explore some ratios that
occur in nature.
