Cyber Combos

In this lesson, students will have fun learning about combinations. After collecting a variety of sunglasses and t-shirts, students will divide into groups and make as many combinations of t-shirts and sunglasses as possible. Students will discover that six combinations are possible with three t-shirts and two sunglasses. The class then views clips from the Cyberchase episode "A Day at the Spa" to see how the Cyberchase team overcomes problems using combinations. The lesson culminates in a fashion show.

Raising the Bar While Hogging the Ham

This lesson teaches students the importance of using the appropriate scale when constructing a bar graph. In Cyberchase episode "Raising the Bar" the Cyberkids discover bugs in the cybrary and report this to Ms. Fileshare. Through some clever detective work, problem solving skills, and clues from a "Squeaky Voice," the kids demonstrate how scale is needed to construct a bar graph that can prove their accusations against their rival, Hacker. Segments of this episode, interaction on the Cyberchase Web site, and activities requiring the use of data in the construction of a bar graph to make a convincing argument will provide children with an understanding of how bar graphs can be used to compare values of different things quickly and easily.

Donut Dinero

This lesson teaches students to construct a monetary system. Students will learn how monetary systems are based on a standard unit of value that consequently can be broken down into fractions or expanded into multiples. Like the Cyberkids in the Cyberchase episode "Trading Places," students will create their own monetary system and use their system of money to exchange goods for tokens of different, agreed-upon fixed values.


Shh...It is a secret!

In this lesson, students will learn with the Cyberchase kids and the episode "Codename: Icky" how codes are created and deciphered. Students will test their skills on the interactive Cyberchase Web site and then apply their new found coding skills to construct a code of their own.


Less than Zero

In this lesson, students examine negative numbers. By playing a number game, viewing segments of the Cyberchase episode "Less Than Zero," and interacting with the companion Web site, students will recognize the relationship between positive and negative numbers and be able to add and subtract them.


I'll Halve S'more Please!!

Students will learn and apply their skills in identifying the parts of a fraction, reducing fractions, and adding fractions with common denominators. Using fractions in the Cyberchase episode, "Zeus on the Loose" and in several interactive Web sites, students will learn to manipulate fractions with ease.


The Fourth Quadrant of Proportiona

This lesson allows students to learn the importance of using size and scale to measure the world around them. By viewing segments of the Cyberchase episode, "Size Me Up", and logging on to the companion Web site, students will have fun while gaining an understanding of size and scale and their applications to real-world problems.


Gotcha Covered, Pardner!

In order to save the day, students will work with the Cyberchase kids to prove that regular and irregular shapes may have the same area. Interactive Web sites will provide students with practice in calculating both area and perimeter, and real-world problems will encourage students to discover that math is fun and something we experience, not just in school, but all around us, everyday.


Relative Ratios

This is an interactive, media-rich lesson in which students examine proportions. By experiment, students will discover that proportions are made up of equal ratios each containing the same building blocks. Using video and the Internet, students will learn how proportions are used to estimate quantities and then apply their knowledge of direct relationships to problems in planetary science.


Sew, You Want To Quilt?

History can be told through quilts as they are passed down through generations within families, keeping cultural traditions present. Through video and the Internet students will connect the mathematical concept of patterns to create a class quilt. Students will also become familiar with artist Faith Ringgold, an African-American artist from New York who uses quilts as her painting canvas.


Only the Shadow Knows

Have you ever been followed by your shadow? Or have you ever followed it? Through the activities presented in the lesson, students will become familiar with how shadows are formed and be given an understanding of how the shape and length of shadows are dependent upon the position and manipulation of the light source.


Picking Pythagoras

This is an interactive media-rich lesson in which students examine the Pythagorean theorem. By experiment, students will discover that side measurement is important in determining the angle classification of a triangle. Using the Internet, students will prove the Pythagorean theorem and use it to solve problems.


Data, Data, Everywhere...and What Am I To Think?

In this world of ever-increasing information our students must learn to collect, analyze, and interpret data for practical application and problem solving. This lesson unit is designed to streamline the introduction of several graphical organizers and how to use them most effectively. The students will visit Internet sites to learn of new data presentation modes and how to interpret various types of data.


Significant What?

Are your measurements accurate? How precise is that measurement? Many students read these two questions and suppose they are asking the same thing. This lesson differentiates between "accuracy" and "precision."



A Picture is Worth a Thousand Words

Students will travel the Internet to find examples of different types of graphs and analyze those graphs for statistical data. They will also select topics of interest and decide which graph type will best depict various kinds of data, and then will create the graphs.



Exploring the Smithsonian

This virtual tour of the Smithsonian Institution in Washington, D.C., provides students with an opportunity to practice basic arithmetic skills and percent computations.



Fabulous Funnels

This is an interactive Internet lesson in which students will learn what tornados are, how they are created, measured, and their effects on communities. Students will keep a journal of their activities and keep track of daily tornado and supercell activity throughout the United States by monitoring the U.S. National Weather Service and National Oceanic and Atmospheric Administration warning site.



Growing, Growing, Graphing

In this statistics lesson, students focus on China's population growth. They graph data on graph paper using a graphing calculator or spreadsheet software. Students predict future population numbers and decide if the population growth is linear or exponential.



How Big? How Small?

Using a variety of Web resources relating to the solar system and microworlds, students will explore the Internet and note occurrences of objects and measurements that are very, very small and very, very large.



Living on Your Own -- Let's Calculate the Cost!

This lesson is a fun way to review basic math skills such as addition, subtraction, multiplication, division, finding averages, and working with percents. More importantly, it shows how these skills are applied to real life situations that are of particular interest to this age group.



Proof of the Century!

Students learn to do Web research in the field of mathematics. They learn about mathematical proofs and apply them to the Pythagorean theorem. Students also explore the general ideas of Fermat's Last Theorem.



Tracing Math's Evolution

In this lesson, students will use the Internet to discover the identities of several current and historically significant mathematicians. They will be able to explore the contributions of different mathematicians and recognize that mathematics is an integral part of many careers.



Understanding Pi

Students learn the mathematical value of pi through the process of measuring circumference. Students conduct hands-on calculations of cylindrical objects, demonstrate the properties of a circle, and discover for themselves how pi works.



Virtual Polyhedra and the Real World

Using Web resources, students will study the complex geometric structures, polyhedra. Students will examine virtual reality models, create three-dimensional paper models, and view photographic, graphic, and animated examples of polyhedra.



Women In Math

Students explore the lives and careers of women who have made historic and contemporary contributions to the fields of mathematics and computer science.
