The Quest Players can choose from different adventures and customize their own characters, returning to play as often as they like, in an ongoing 'Quest' to stop Hacker. Adventure topics include: Eco-Haven Emergency Math Topic: Measurement, Patterns, Deductive Reasoning Science Topics: Biology, Physics Stop Hacker before he ruins Eco-Haven! Use math and science to care for the plants and animals of Eco-Haven, clean up Hacker's mess, and repair the Eco-Protector. Big Idea: Math can be used to unlock and explore science ideas. Mission: Motherboard Math Topic: Saving, Spending NCTM Standard: Number & Operations Practice earning, saving and spending as you search different Cybersites for the objects needed to save Motherboard. Big Idea: Saving: When you save small amounts of money at a steady rate, your savings will grow larger and you can predict when you will have the amount you need to buy what you want. Spending: To spend money wisely, compare the amount of money you have with the cost of the things you need to be sure you can afford your purchases. Race For Radopolis Math Topic: Budgeting NCTM Standard: Number & Operations Beat Hacker at the Shredfest to regain control of Radopolis. Budget your money carefully to buy parts for your winning skateboard. Big Idea: Use a budget to plan future expenses and you can control your spending so you don’t run out of money.

		Score the Pour Math Topic: Making Hard Problems Easier NCTM Standard: Problem Solving Using containers of different sizes, the player must measure volumes of a liquid from one quart to eight quarts. Big Idea: If you can spot an easy problem inside a hard one, the simpler solution can help you solve the harder problem.
		Double the Donuts Math Topic: Growth by Doubling NCTM Standard: Algebraic Thinking In this activity, a player gets to see how quickly the donuts add up when their number increases by doubling. Big Idea: When something grows by doubling, it gets large surprisingly fast, growing ever faster the longer the doubling continues.
		Eye of Rom Math Topic: Inverse Operations NCTM Standard: Number & Operations In the Eye of Rom, players wind their way through a maze following directions, and then wind their way back using inverse operations. Big Idea: Find the inverse of an action and you can undo it, putting things back the way they were.
		Railroad Repair Math Topic: Decimals NCTM Standard: Number & Operations The player is challenged to repair a series of train tracks using a set of spare tracks of sizes between 0.1 and 1.0. Big Idea: Use a decimal point to join tenths with whole numbers and you have a decimal system you can use to easily record, compare and combine whole numbers with fractions.
		Space Coupe to the Rescue Math Topic: Negative Numbers NCTM Standard: Number & Operations In Space Coupe to the Rescue, the player needs to master the concept of positive and negative numbers in order to track down a series of virus pods that Hacker is placing in various areas of a Cybersite. By choosing a positive or negative number, the player controls the vertical position of a spaceship. If the spaceship reaches the same vertical position as a virus pod, the pod is destroyed. Big Idea: Numbers don't have to stop at zero! Negative numbers - numbers that are less than zero - can extend the range of what you can measure on a scale and give you the ability to compare numbers using direction as well as amount.
		Disguise Combos Math Topic: Combinations NCTM Standard: Data Analysis & Probability, Problem Solving In this game, the Cybersquad uses disguises to fool Hacker. The player helps by creating as many combinations of wigs, glasses, and beards as possible. As the game progresses, the relationship between multiplication and combinations is revealed (i.e. if you have 3 wigs and 2 pairs of glasses, you can make a total of 6 combinations). Big Idea: Overwhelmed with choices? Lists, tables and tree diagrams help you master the combinations.
		Number Machine Math Topic: Place Value NCTM Standard: Numbers & Operations The player attempts to take 3 digits assigned by the computer and arrange them to create a number that will be of greater value than a 3 digit number of Hacker's. Students have several choices of position for each number and must have a sense about the relative size of the number and a strategy for how to position the digits for the best advantage. Big Idea: Let numbers stand for things in a regular pattern, and you have the power to keep track of anything and everything on Earth.
		Vortex Math Topic: Elapsed Time NCTM Standard: Measurement In Vortex, players must click on the right shapes to score points. The catch: They have to score 3 points in the first 15 seconds in order to make it to the next round. Big Idea: When you need to know how much time has gone by during an event, note the starting and ending times with a clock and find the difference.
		Star Gazing Math Topic: Angle Measurement NCTM Standard: Measurement In order to help Digit fill his Cyberscrapbook, the player needs to point a telescope at the right angle to line up with planets. Big Idea: To turn something so it points in just the right direction, use an angle to measure the size of the turn.
		Wacky Ruler Math Topic: Linear Measurement NCTM Standard: Measurement In this hybrid print and online activity, kids print out a ruler which is missing some of its markings. Another printed page displays several "cyber worms" of varying length. Kids are challenged to find the lengths of the worms using the ruler. They can then check their answers online. Big Idea: To measure length and communicate your results easily and precisely, identify a system of units based on a single standard length that everyone using it agrees on.
		Maze and Marbles Math Topic: Timekeeping NCTM Standard: Measurement This "Rube Goldberg" type activity involves a marble machine that drops marbles at a steady rate, registering one tick on a digital display. The marble machine must stay full enough to complete 60 ticks. To keep the machine full, the player engages in a "Pong" type activity to guide a falling marble through a moving maze, and into a tube to refill the machine. Time is of the essence! Big Idea: To measure the passage of time, choose a starting point and count up the beats of something that repeats at steady, regular intervals.
		Tangrams Math Topic: Area NCTM Standard: Measurement In this activity, the player can choose to place Tangram puzzle pieces to create up to 13 shapes. (A Tangram is an ancient Chinese puzzle that is composed of 7 geometric shapes: 2 large triangles, 1 medium triangle, 2 small triangles, 1 parallelogram, 1 square.) The player can choose to place the pieces to re-create the shape with or without an outline of the shape. Big Idea: To find the area of an object, count how many squares fit on it. But there's an easier way! Measure an object's dimensions, and you can use mathematics to calculate its area.
		Can You Fill It? Math Topic: Liquid Volume NCTM Standard: Algebraic Thinking, Measurement In this pouring activity, the player selects a large, medium, or small measure to "pour" liquid into an even larger container. The player observes how the liquid partially fills the container, and must estimate how many "pours" will fill it to the top, without overflow. The player is given a sense of how the shape and the dimensions of a container influence how the liquid rises to fill it. The containers to be filled include: a cylinder, a beaker, and a funnel-shaped container. Big Idea: Just because one container appears bigger than another to the eye doesn't mean it holds more liquid. A container's volume depends on all its dimensions.
		Bugs in the System Math Topic: Bar graphs NCTM Standard: Representation In this Web Activity, the player has to clear a room of bugs by clicking and dragging them onto a graph. Big Idea: Represent numbers of different things in a bar graph and you can compare values at a glance, communicate with others and even persuade them.
		Make a Match Math Topic: Equivalent Fractions NCTM Standard: Numbers & Operations In Melvin's messy lab, players need to find matching potion bottles. The bottles can be matched using the information on their labels-- equivalent fractions. Big Idea: Fractions that look different can represent the same portion of a whole.
		13 Ways to a Half Math Topic: Fractions NCTM Standard: Numbers & Operations This activity allows the player multiple ways of viewing half of a square that has been divided into eight parts. The player selects and fills each of four parts with color to create a type of "quilt square" pattern. To find 13 different representations of "half", the player must use a systematic way of selecting the design without repeating any previous ones, and the player must also recognize a rotation -- that is, if a pattern is repeated, but in a different position. Big Idea: When you need to divide things up into parts and share them, fractions are the numbers to use.
		Send in the Trolls Math Topic: Data Clusters NCTM Standard: Data Analysis & Probability The player is challenged to arrange a series of trolls in order to send the troll of middle-height to a beauty contest. Big Idea: When you have different numbers that describe members of a group, you can often find one number to fairly represent the group as a whole.
		Coin Toss Math Topic: Probability NCTM Standard: Data Analysis & Probability The player chooses to flip a coin between 2 and 10,000 times. The number of heads and the number of tails for this set of flips is posted and a bar graph displays the results. There is also a display for the cumulative tally and a bar graph that reflects the cumulative percentage. The player is able to observe that. Big Idea: A game of chance is fair when nobody can tell who will win, but everyone has the same chance of being a winner.
		Poddle Weigh-in Math Topic: Algebraic Thinking NCTM Standard: Algebraic Thinking, Representation, Connections This game introduces the concept of variables-- that something can be a 'container' for a number. The poddles have lost the numbers that usually show up on their shirts. By placing each poddle on a scale and adding weights, the player can determine what number the poddle is. Big Idea: You can use an equation - a statement that two different expressions are equal to each other - to find unknown values that make the equation true.
		Spaceship Builder Math Topic: Perimeter/Area Relationship NCTM Standard: Measurement The player creates a fleet of Cyberspaceships using pieces of uniform length. The relationship between perimeter and area is explored as the player discovers that ships with the same perimeter can have different areas. Big Idea: Different shapes bounded by the same perimeter can enclose very different areas.
		Cyber Pattern Player Math Topic: Patterns in Music NCTM Standard: Algebraic Thinking The Cyber Pattern Player allows kids to create audio patterns visually. The player loops through a simple grid of boxes can be toggled on and off to produce various sounds. Big Idea: Patterns are sequences that repeat or change in an orderly way. You can use patterns to predict the next step in solving a problem.
		Jigsaw Puzzle Math Topic: Scale and Size NCTM Standard: Geometry, Algebraic Thinking This game resembles a traditional jigsaw puzzle except for one difference: Some of the pieces have been scaled up or down and the player is challenged to resize the pieces in order to complete the puzzle. Big Idea: You can create an exact likeness of something -- though one that is a different size -- by multiplying the size of every part of your original by the same number.
		Pattern Quest Math Topic: Patterns NCTM Standard: Data Analysis & Probability This activity is based on a form of "Mastermind" -- in which the player attempts to identify a 4-term pattern using the strategy of guess and check. Then feedback is given, identifying which pattern is correctly identified. By using clues, and eliminating wrong guesses, the player attempts to deduce the pattern in the fewest number of guesses. Big Idea: Data is a lot more than "a collection of numbers." When you gather it, organize, and analyze it, you can discover useful information hidden in the numbers.
		Crack Hacker's Safe Math Topic: Patterns NCTM Standard: Algebraic Thinking In Crack Hacker's Safe, the player must complete a sequence of patterns to crack Hacker's safe. Big Idea: Patterns are sequences that repeat or change in an orderly way. You can use patterns to predict the next step in solving a problem.
		Crack the Code Math Topic: Codes NCTM Standard: Algebraic Thinking In this activity, the player uses a decoder to uncover Digit's secret message. Big Idea: You can use a code (a communication system that substitutes one thing for another) to send top secret messages as long as your code has an adjustable rule that can be reversed to read the message.
		Stop That Creature Math Topic: Functions NCTM Standard: Algebraic Thinking The player must shut down a series of creature-controlling machines by determining the solution to a function. Big Idea: When changing one quantity determines the value of another, they are connected by a rule you may not see. Find the rule and you can predict any outcome.
		Estimation Contraption Math Topic: Ballpark Estimation NCTM Standard: Number & Operations In this activity, the player has 60 seconds to take a group of numbers and provide an estimate of what the numbers would add up to. The game gives kids an opportunity to practice rounding numbers and adding them up. Big Idea: To be confident about your solution to a problem, make sure the answer is reasonable -- that it is 'in the ballpark'.
		Jellybean Jostle Math Topic: Estimation NCTM Standard: Number & Operations In this activity, kids print out grids with pictures of jellybeans on them and show them to their friends. To win, their friends must estimate within 10 jellybeans of the total number. Big Idea: Sometimes using a close answer is good enough for the problem you are solving.
		Cyberchase Squares Math Topic: Counter Examples NCTM Standard: Reasoning & Proof In this online game show, the player needs to decide which character states the counter example to a given statement. Big Idea: When people use words like always, never, all or none to claim something is true, be suspicious! Such claims are often false, and you need only a single counter example to disprove them.
		Logic Zoo Math Topic: Logic NCTM Standard: Problem Solving This activity presents the player with a variety of fantasy animals and lists their descriptive features. The player must sort the animals into fields at the zoo by the animal characteristics. This activity familiarizes the player with the use of the Venn diagram as a sorting tool. Big Idea: When you have to choose from a confusing mix of possibilities, you can use logic -- a set of tools for thinking clearly -- to picture and refine your choices so you can get exactly what you want.
		Point Out the View Math Topic: Point of View NCTM Standard: Geometry In Point Out the View, each member of the Cybersquad is looking at a bunch of blocks from a different place. The player must show what each person sees from their point of view. Big Idea: Because what you see depends on your point of view, different people looking at the same objects can see them differently and disagree about what they are seeing.
		Crossing the River Math Topic: Using Models NCTM Standard: Geometry In this logic puzzle, the player needs to determine how to get a number of Cyberchase characters across a river in a small boat. The trick is that either two kids or one adult can fit into the boat and someone always has to steer for the boat to get across. Big Idea: Make a model - a simplified version of something complicated - and you can easily and safely understand how it works.
		2D to 3D Morphing Math Topic: 2 & 3D Geometry NCTM Standard: Geometry This activity allows the player to print out a "net", which is a geometric pattern outline for creating a 3-D solid. The print outs include a net for creating a cube, a pyramid and an octahedron. This allows for a do-it-yourself level of interaction on the topic of making a 2-D shape into a 3-D solid. Big Idea: When you follow simple rules to make flat geometrical shapes, and join them together, you can discover new shapes that, instead of staying flat, rise up to make three-dimensional objects!
		Bike Route Math Topic: Navigation NCTM Standard: Geometry, Measurement & Representation Inez needs to complete a number of chores. The player is challenged to find the shortest route that will complete all of the tasks. The game is layed out as a grid and the player can move about the grid leaving a "trail" of arrows showing the complete path. Big Idea: A map is a mathematical tool you can use to find your way from one place to another, anywhere on earth.
		Symmetrizer Math Topic: Symmetry NCTM Standard: Geometry This activity introduces the player to reflections and angles through experimentation with a kaleidoscope. By moving the mouse through the kaleidoscope, the player can observe the reflections in 4 squares which have been divided into 8 triangular mirrored panels. The experimental nature of the activity is exciting, and is accompanied by a good explanation of how the reflections are constructed in a kaleidoscope. Big Idea: Symmetries are patterns you can find hidden within many objects that create balance, order, and a pleasing regularity in the world around us.
		Virus Hunt Math Topic: Navigation NCTM Standard: Geometry This activity presents a map with obstacles and the player guides a space pod to the location of a hidden object. The player uses arrow keys to set the direction the space pod moves and a tracking device reports the location of the object -- relative to the space pod -- as North, East, South, West, etc. Big Idea: A map is a mathematical tool you can use to find your way from one place to another, anywhere on earth.
		Slueths on the Loose Math Topic: Proportional Thinking NCTM Standard: Algebraic Thinking The player is challenged to find the height of various creatures using a variety of clues. Big Idea: Some body parts are proportional to others - the length of one part is always the same multiple of another - so by measuring one part, you can predict the lengths of others, or even the size of the whole creature!
		Where is Digit? Math Topic: Circles NCTM Standard:Geometry Digit is lost in the Northern Frontier! Use the power of circles to locate him. Big Idea: You can use a circle to find all the points that are the exact same distance from a particular spot.
		Mission Magnetite Math Topic: Percent NCTM Standard: Number & Operations To stop Hacker, you must match up fractions that are represented three different ways. Big Idea: If you understand the relationship between a percent, its fraction and its picture, you can often solve problems by substituting one form for another.
