6.RP.1. Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”

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)

Ratios
From YouTube, produced by Lawrence Perez


In this video they are showing ratios, how to write them as a fraction (reduce if possible), comparing ratios using LCD, comparing decimal ratios, and comparing fraction to decimal. A few examples are done to complete this video. Video is good quali...ty and good for all students as a review or initial learning of the topic.

This is a humorous way to introduce ratios. What do you do when someone asks if you listen to country music backwards, but won't give you the chance to answer? In this humorous animation, who speaks how many words turns out to determine whether a dat...e goes well or horribly. Bad Date addresses number and operations standards and the process standard, as established by the National Council of
Teachers of Mathematics. (3:37)

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.
