Resource: Choosing the Most Orange Crystal

In this video segment from Cyberchase, the CyberSquad looks at seven different crystals to determine which crystal displays the largest amount of orange color, and thus has the most power. They find that some crystals have more stripes of certain colors than others but not all the stripes are the same size. The CyberSquad solves the problem by thinking about the stripes as fractional parts of the crystals, and then comparing the fractions to determine the largest one.

Print Frame and FocusHere are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.
What is Frame, Focus and Follow-up?
Frame: Sometimes you might have to compare fractions to see which is bigger. Do you know which is more, ½ or ¼? How do you know? How about comparing 1/8 and 2/8? Which is bigger, and how do you know? Are denominators important in comparing fractions likes these? Why? What if fractions have different denominators, like 1/8 and 3/4? How do you go about comparing fractions like that?
Focus: As you watch this video segment, think about how the CyberSquad compares the different amounts of orange on the various crystals. Consider how their knowledge about fractions helps them. Are denominators important? How does the CyberSquad compare fractions with different denominators?
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.Source: Cyberchase: “A Piece of the Action”
