In this video segment from Cyberchase, the CyberSquad is trapped in one of the Spheres of Fears, and they are trying to get through a gate to escape. The key to the gate is locked inside a can, and in order to access the key they must attach the correct label to the can. After guessing incorrectly on the first try, the CyberSquad decides to take some measurements to find the correct label. Using two circles nearby, they compare the diameter of each circle to its circumference. They realize there is a special relationship between the circumference of a circle and the length of its diameter. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.
In this Cyberchase activity, students begin by using manipulatives to share objects among different sized groups. After watching a video clip that demonstrates dealing out rounds (or sets) of objects to solve a problem, the students work on a few division problems on their own. A second video clip demonstrates how to solve such problems using numbers. With the handout, students learn to write these problems as multiplication and division facts.
Lesson plan using a Cyberchase activity, gives students practice in estimating heights and lengths of objects when the measurement tools are not rulers. Two different kinds of measurement units allow students to measure by repeating the measurement with a single smaller object, and to measure with an object that is composed of multiple repeating units.
Lesson Plan using a Cyberchase activity that provides students with practice in accumulating positive and negative point totals in the context of a competition. The activity is motivated by the For Real segment of a Cyberchase episode that emphasizes positive and negative numbers.
In this video segment from Cyberchase, Matt, Digit and Slider must create an exact copy of a large ring in order to activate a powerful force and foil Hacker. To make sure the copy they make is perfect, they have to know what the ?radius? of a circle is and figure out a way to carefully measure it. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.
In this lesson, students encounter a situation in which they must solve for the value of a variable. The equations are in the form of p = qx, in which q, x, and p are all whole number values. This CYBERCHASE activity is motivated by an episode in which the CyberSquad plays a game against Hacker to catch enough "gleamers" to power up the Cyberspace ship. If they win, they get the Encryptor Chip. But first, they must figure out the relationship between gleamers and power glows.
