Fractions, percents, and models are all ways to represent a given amount. In this interactive game from Cyberchase, you must stop Hacker by cracking a code to empty the fuel from his rocket. The code is made up of percentages that you need to match up with two equivalent forms of the percentage (a fraction and a drawing). Select a percentage value and then drag the equivalent fraction and picture to the proper circles. When you have a correct match you will move on to the next level. But you must act quickly; if Hacker fills the rocket with magnetite faster than you can match the values, you must start over again.

Frame/Focus

Here are some Frame, Focus and Follow-up suggestions for using this video in a math lesson.

What is Frame, Focus and Follow-up?

Frame: There are many ways to describe a part of a whole. Money is often described in decimal amounts, whereas recipe measurements are usually fractions. Graphs, such as a pie chart, make use of the visual representation of a part of a whole. How about grades on a test? Many times your score is written as a percentage, such as 95%. If you understand the relationship between a percent, its fraction and its picture, you will find that you can often solve problems by substituting one form for another.

Focus: In this interactive game, match the percentage with the proper fraction and diagram. Note which ones, if any, that you have trouble with.

• How could you tell the difference between the values? How did you know it was a percentage? Or a fractions? Or a picture?
• Did you have to simplify any of the fractions?
• Which one was easier—finding the matching fraction or the picture?
• Was there ever more than one correct combination of values?
