Reclaiming the Power
In this video segment from Cyberchase, Hacker has consumed most of the powersupplying Cosmic Crumpets. Only pieces of crumpets are left. The CyberSquad must help Shari Spotter to restore the Frogsnorts wizards’ power by putting the remaining pieces of crumpets together, which involves the addition of fractions and converting mixed numbers to improper fractions. Then they must share the pieces equally among the seven wizards.

Choosing the Most Orange Crystal  Cyberchase
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.

The Use of Exponents
Students are introduced to exponential form and learn to write repeated multiplication using exponents and to evaluate expressions in exponential form.

Lily Pad Escape
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.

Several Short Rails Make More Than A Whole
In this video segment from Cyberchase the CyberSquad is trying to get to the Mother’s Day Harvest on the Madre Bonita Express train. Hacker has ripped out a piece of the train track, however, and Digit must use decimal addition to find a way to repair the track using only the pieces available.
Grades: 35 
Railroad Repair Using Decimal Addition
In this Cyberchase interactive game, Hacker has removed some of the tracks on the TransCyberspace Railroad. The challenge is to repair the tracks so that the Cybertrain can get back to the central station. A set of spare tracks that range in length from 0.1 to 1.0 will be used to fill in the gaps. In many cases it will be necessary to use a combination of two or three pieces to fill in the missing part of the track. All the gaps on the screen must be filled before the train will move.
Grades: 36 
Planning a Budget
Students practice column addition and lining up decimal points in the context of money while they watch a video segment. Assessments provide more practice adding numbers in columns, and students troubleshoot an error in misaligned decimal addition.
Grades: 35 
Introducing Decimals and Simple Decimal Addition
Students are asked to recognize the equivalence of fractional tenths and decimals and to do simple decimal addition to find lengths both shorter and longer than 1.
Grades: 36,13+ 
How Many Rails for the Detour?  Cyberchase
In this video segment from Cyberchase, the CyberSquad must build a rail line to get around the mountain to transport flowers gathered from Thornium Mountain. To do this they must complete decimal addition to figure out how long to make the new rail line. After looking at their sum, the CyberSquad believe that something is not quite right. They realize they did not line up the decimal points when they added the numbers, so they fix their mistake and add up the numbers again.
Grades: 48 
Creating Equal Shares
Students practice fractions by sharing certain numbers of objects among different numbers of people. They begin with unit fractions and move to sharing multiple objects among multiple people, in which a < b, and to produce fractions less than one.
Grades: 36,13+ 
Crumpets Recipe
In this video segment from Cyberchase, the CyberSquad has to help Shari Spotter make a batch of Cosmic Crumpets in order to give the masters at Frogsnorts their power. The recipe they have is for four crumpets, but they need to make eight crumpets. Everything in the recipe has to be doubled, including some tricky fractions which Shari and the CyberSquad find they must convert from improper fractions to mixed numbers.
Grades: 35 
The Puzzle of the Amulet of Amagansett
In this video segment from Cyberchase, in order to free the CyberSquad from the Vortex, Wicked and Digit must find the Amulet of Amagansett. When they find the Amulet they realize it is missing some of its jewels. They use what they know about numerators and denominators to figure out how many jewels are missing.
Grades: 34 
Multiplying Fractions of the Form a/b of c
Students study fractions and practice writing arithmetic sentences using multiplication and specific proportions.
Grades: 58 
Mission Magnetite
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.
Grades: 35 
Locating and Ordering Equivalent Fractions on the Number Line
Students find ways to share differentsized items equally between 2 people as well as to find equivalent fractions on a number line and to order those fractions by size.
Grades: 36 
Learning to Distinguish Numerators and Denominators
Students learn to recognize representations of fractions as well as identify numerators and denominators, understand the relationship between the number of parts into which a whole is divided, and the number of those parts that are present
Grades: 35 
Introducing NonUnit Fractions and Equivalence
Students interpret fractions in which the denominator describes the number of equal parts and the numerator describes how many of those parts one has. They are also introduced to naming equivalent fractions by dividing a circle.
