## Month: July, 2012

Our heroes learn how lists, tables and diagrams can help them manage too many different ways to combine things.

For Real segment: Harry combines a few basic sandwich ingredients to make many different kinds of sandwiches.

Learning Goals

Is your child overwhelmed by choices?  Lists, tables and tree diagrams can help her master the combinations.

Topics: Problem Solving, Using Data: Combinations

The CyberSquad goes to the Northern Frontier where they use logic and Venn diagrams to rescue the Lucky Charms.

For Real segment: Bianca uses a Venn diagram to figure out how to order a pizza with toppings arranged so anchovies are not near her pieces.

Learning Goals

When your child has to choose from a confusing mix of possibilities, he can use logic – a set of tools for thinking clearly – to picture and refine his choices so he can get exactly what he wants.

Topics: Problem Solving: Logic

Measuring liquid volume becomes more difficult when the kids and Digit are caught without measuring tools and have to replace Motherboard’s cryoxide before she overheats!

For Real segment: Bianca has to feed twins the same amount of formula, but the bottles are different shapes so she has to figure out which hold the same amount.

Learning Goals

Just because one container appears ‘bigger’ to the eye doesn’t mean it holds more liquid than another. A container’s volume depends on all its dimensions.

Topics: Measurement: Liquid Volume

The CyberSquad has to figure out unknown numbers in equations so they can save Topsy Turvy Island from turning inside out.

For Real segment: Harry figures out how he can create a totally new look for just \$100 as he shops for a new jacket and pair of pants.

Learning Goals

When your child uses a letter to stand in for a number that repeats or changes in a problem, she can simplify the arithmetic and make the problem easier to solve.

Topics: Pre-Algebra

Our heroes invent secret codes to send messages so Hacker can’t figure out their plans to save Icky, the underwater cyber-slug.

For Real segment: Julio and Harry swap coded messages, but when Harry takes a shortcut decoding an invitation from Julio, he ends up in trouble!

Learning Goals

Your child can use a code (a communication system that substitutes one thing for another) to send top secret messages as long as the code has an adjustable rule that can be reversed to read the message.

Topics: Pre-Algebra: Codes

The CyberSquad uses line graphs to solve the mystery of why the reservoir in Sensible Flats has suddenly gone dry.

For Real segment: Harry uses a line graph to predict that he can make the 20-mile trip on his unicycle to visit his grandmother before dark.

Learning Goals

Your child can use a line graph to tell a story about how things change, and to make predictions.

Topics: Science & Engineering, Using Data: Line Graphs

Hacker and the CyberSquad are prisoners in Shagri-La and must master the art of problem solving to win the tricky dragon game and gain their freedom.

For Real segment: Harry takes over his brother’s paper route for a week, but has to rework the route using problem solving skills to get the job done.

Learning Goals

When your child tackles a tough math problem, he can treat it like a challenging game. His chances of solving it will be better if he follows a game plan, and the more he plays, the better he will be at problem solving next time.

Topics: Problem Solving

The kids and Digit use repeated addition and multiplication to take control of an army of Delete’s clones.

For Real segment: Bianca uses multiplication and repeated addition to figure out how many donuts she has to decorate at her new job.

Learning Goals

Is your child stuck on a multiplication problem? Relax! Remember that multiplication is just repeated addition, and your child can use what she already knows to find the answer.

Topics: Using Numbers: Multiplication

Stranded on Nowhere with no money to buy parts to fix the cybercoupe, the CyberSquad trades, barters, and invents a new monetary system with the help of stale donuts.

For Real segment: Bianca finds a gold coin and takes it to a coin expert where she learns about the history of money and the true value of her coin.

Learning Goals

Instead of trading what he has for what he wants, your child can make it easier to buy and sell by creating a system of money where he exchanges goods for tokens of different fixed values.

Topics: Problem Solving, Using Numbers, Money: Monetary Systems

The kids and Digit learn about negative numbers in their latest attempt to rescue Dr. Marbles.

For Real segment: During an ice skating competition, Harry’s performance is so poor his score is a negative number!

Learning Goals

Numbers don’t have to stop at zero! Negative numbers — numbers that are less than zero — can extend the range of what your child can measure on a scale and give her the ability to compare numbers using direction as well as amount.

Topics: Using Numbers: Negative Numbers
