Cyberchase (X) - Geometry (X)

## Predicting Travel Time Using Line Graphs

Icon:

In this Cyberchase video segment, Harry wants to visit his grandmother. He decides that the cheapest way for him to get there is to travel by unicycle, but he wonders if he can get there before dark. Using a line graph, he tries to predict the amount of time it will take to travel the twenty miles, assuming he travels at a constant speed. Once he sets out on his unicycle, he charts his progress on a new line graph. After the first hour he appears to be ahead of schedule, but he is not able to keep up the pace and soon finds himself falling behind.

## Calculating Rectangular Area | Cyberchase

Icon:

In this video segment from Cyberchase, the CyberSquad must measure two differently-shaped parcels of land to determine which has a larger area. The CyberSquad uses tarps, fence posts, and finally a grid made out of rope to count squares and determine the area of each parcel.

## What's a 360?

Icon:

In this video segment from Cyberchase, Harry is snowboarding and wants to do a move on his snowboard known as a "360." He is not sure what exactly a "360" is, but a snowboard instructor teaches him about angles and snowboard moves. Harry finally creates his own snowboard version of a "360."

## Graphing Points on a Coordinate Plane: Harry’s Feet Compete

Icon:

In this video from Cyberchase, Harry decides he needs to start a regular workout schedule. He uses a graph to record his progress. In the accompanying classroom activity, students play a ball-balancing game and record their attempts on a graph to build on the concepts presented in the video.

## Directions to Hen Rock

Icon:

In this video segment from Cyberchase, the CyberSquad follows a treasure map with riddles to find Ivanka the Invincible’s secret treasure chest. One of the riddles asks the CyberSquad to record how much of a turn they make from one object to another. To do this, they have to record the angle of the turn.

## Measuring for an Exact Fit

Icon:

In this Cyberchase video segment, Matt and Jackie must figure out how to construct rectangular lids that match the size of two boxes precisely. They enlist the carpentry skills of one of the Three Little Pigs, who shows them how to use different tools to accurately measure the rectangular lids. For the first box, Jackie finds that she can easily trace the box to make a lid that fits perfectly. The second box cannot be traced, so Matt and Jackie decide to measure the sides of the box and then use the measurements to cut a rectangle of equal size out of a piece of Herculanium.

## Cyberchase | Patterns in Nature

Icon:

In this video segment from Cyberchase, Bianca wants to learn why her plants keep dying, so she transports them in a carriage to the New York Botanical Garden. A helpful plant expert shows her some patterns in plants, including bilateral and rotational symmetry, before discovering the pattern that may be killing Bianca's plants.

## Comparing Regular and Irregular Areas | Cyberchase

Icon:

In this video segment from Cyberchase, the CyberSquad must compare two parcels of land during a land rush. One parcel is an irregular shape and belongs to Hacker. The other parcel is a regular rectangle and belongs to Judge Trudy. By dividing each parcel into squares and triangles, they prove that the two shapes have the same area.

## Arranging Desk: Factors and Multiples | Cyberchase

Icon:

In this video segment from Cyberchase, Harry takes on a job as a substitute teacher. After moving all the desks to create space in the middle of the room, Harry displays his juggling talent. When putting the desks back into rows, the class is faced with the task of creating rows with an equal number of desks. In doing this, the students learn about the factors of twenty-four.

## Geometry and Classification of 2D Figures: Bianca Busts a Move

Icon:

In this video from Cyberchase, Bianca breaks her friend’s tabletop when she’s practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying classroom activity helps students advance their understanding of perimeter and area by creating their own tabletop designs. This resource is part of the Math at the Core: Middle School Collection.

## Surface Area , Area and Volume: The Big Sleep

Icon:

In this video from Cyberchase, Bianca is planning a sleepover birthday party. To figure out the maximum number of friends she can invite, she decides to count how many sleeping bags she can fit over the area of her living room floor. In the accompanying classroom activity, students use the concepts presented in the video to determine the area of multiple shapes. This resource is part of the Math at the Core: Middle School Collection.

## Hoop Dream: Use a Diagram to Solve Real-World Math Problems

Icon:

In this Cyberchase media gallery, a series of short videos shows how the Cybersquad diagram their own attempts to score a basket in a game called Jimaya Jam in order to win their release from confinement. In the accompanying classroom activity, student pairs play a game of their own called Player Plotting, in which students independently plot points on a coordinate plane and see if the diagrams they create from their points match. This resource is part of the Math at the Core: Middle School Collection.

## Skateboarding

Icon:

In this video segment from Cyberchase, Bianca injures her ankle while skateboarding and is confined to her bed. She has trouble reaching a few objects from her bed until her friend gives her a device made up of collapsible parallelograms. Bianca finds that by adjusting the parallelograms, she can now extend her reach.

## Finding the Circle's Center | Cyberchase

Icon:

In this video segment from Cyberchase, the CyberSquad must reclaim the Totally Rad Ring by making an exact duplicate. To do that, they must determine the radius of the ring and the exact center. The ring then must be placed in the exact center of a circle.

## Two Sightings, Different Information | Cyberchase

Icon:

In this video segment from Cyberchase, the CyberSquad is trying to locate a lost Transformatron. Matt can see it along one line, while Jackie says she can see it along a different line. Digit and Inez try to figure out how this is possible.
