This plan includes lessons for two 45-minute classes and two optional extension activities.

The first extension activity is for teachers of U.S. history who may wish to help students better understand the Federalists and Antifederalists and their views about the balance of power between states and the national government.

The second extension activity could be used in history, government, civics, or law classes by teachers who wish to connect students to current issues involving federalism.

In this video segment from Cyberchase, Matt and Inez have to choose a cage for Spout the Whale. The cages they find in a store come in different sizes and Matt and Inez are not sure of Spout?s exact size. They use estimation and non-standard measurements to estimate Spout's size and select the best cage. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

Lesson plan using a Cyberchase activity where students learn about body matches, measuring one part of the body using another body part. They learn about non-standard measures and relative measurement. This activity is motivated by a Cyberchase episode in which the CyberSquad must act as crime scene experts to find out who kidnapped Chewcrocca, a giant cybercrocodile.

In this video segment from Cyberchase, Harry plays a game of chess with a young friend and suggests a wager on the game. Harry?s friend uses a story to explain how putting a penny on the first square and then doubling the amount on each square of the chessboard can generate a tremendous amount of money over time. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

Video segment from Cyberchase, Harry decides he wants to compete in the Northern Hemisphere Games in New Orleans. He must compete in four events and score a total of 50 points to make the team. In each event, if he does well he can score high, but if he performs poorly, his score could become a negative number. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

n this activity, students learn some of the pitfalls of doing surveys. They also learn to examine the shape of data, including data clusters, the range and typical values. This Cyberchase activity is motivated by a video segment in which the CyberSquad searches for Hacker's castle based on a survey of where town residents have last seen him.

In this activity, Franklin goes to the store to purchase supplies to complete a painting job. He works with Laverne to estimate the cost of materials using rounding and uses that estimate to calculate his rate of pay based on how long the job takes him.

Lesson plan using a Cyberchase activity, students are introduced to a problem that gives them a sense of how quickly exponential growth accrues in the classic problem about a chess board and grains of rice. The context is extended to consider applications using money growth and chain letters. They are introduced to the algebraic representation for exponential growth.

Lesson plan using a Cyberchase activity where students learn about two-dimensional and three-dimensional shapes. Students watch a video clip and then identify the shapes that they see in the clip. In Assessment A, students are asked to identify shapes. In Assessment B, they have the opportunity to create a three-dimensional shape from a cutout.

In this video segment from Cyberchase, the CyberSquad is trying to escape from a desert island by crossing a large body of water. They find a special lily pad that was left for them by the Red Warrior. When the lily pad is put in water it doubles and the number of lily pads keeps on doubling. The CyberSquad tries to use this doubling effect to help them create a lily pad bridge to cross the water and escape. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

In this video segment from Cyberchase, Bianca helps her friend make rock candy and discovers some interesting shapes. They also visit The Museum of and look at a variety of rocks and minerals, identifying and describing the many 2-D and 3-D shapes that are found in these specimens. Teaching tips are also provided that discuss frame, focus and follow-up suggestions for using this video in a math lesson.

In this video segment from Cyberchase, Bianca is getting ready to run in a race on a 200 meter track. She notices that the starting positions in the six lanes are at different points along the track. She believes this is unfair and sets out to measure the distance between the starting point and the finish line in both the outside and the inside lanes. 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 will examine the role of precedent in Supreme Court decisions -- why precedents are usually followed and what justices take into consideration when they overturn precedents.

Lesson plan where students are asked to consider how to draw a perfect circle, and learn to do so using a line segment called a radius. They also learn to fold a circle in two directions symmetrically to find its center. This activity is motivated by a CYBERCHASE episode in which the CyberSquad set out to rescue a magic ring from Hacker and deposit it in a safe place.

Lesson plan using a Cyberchase activity, students become more familiar and proficient at metric unit measurement by examining measurement and predictions concerning indoor tracks (200 m) and outdoor tracks (400 m). This CYBERCHASE activity is motivated by a Cyberchase For Real segment in which Bianca competes in her first track meet, but is not convinced that the staggered distances of the lanes on the indoor track are all the same distance.

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.
