Our original lesson plans are developed by Thirteen Ed Online Master Teachers. Starting with tried-and-true lessons that work in the classroom, our Web-savvy teachers have built Web-based activities that use the rich resources of Thirteen/WNET New York and the Internet.

Each month, we will create new lessons based upon outstanding PBS series and around outstanding Web resources.

	Balancing Act	Grades 3-5
	Use a budget to plan future expenses and you can control your spending so you don't run out of money. In CYBERCHASE, the animated math series, the Cyberkids are making a film about frogsnorts. The team collaborates well until they realize they're spending too much too fast. The solution: create a budget. Their efforts are complicated by the spells of the evil Hacker.
	Penguin Tears	Grades 3-5
	Balls that bounce all follow a simple rule - 'angle-in-equals-angle-out' - that you can master to make balls go just where you want, bounce after bounce. In the animated math series, CYBERCHASE, the kids are trapped in an icy cave and must master the principles of bouncing in order to break out. Can they escape in time or will the evil Hacker's plan succeed?
	Hey, Mr. Producer!	Grades 9-12
	It’s not uncommon for secondary school students to study the ups and downs of the stock market, but in this lesson, students will examine the economic roller coaster involved in the production of a Broadway musical. As an introduction to the lesson, students will read a series of online articles to investigate the similarities and differences between non-profit theatre production and Broadway, or commercial, theatre production. Students will view excerpts from BROADWAY: THE AMERICAN MUSICAL, to determine how the costs of producing on Broadway have changed over time, and to understand the economic gamble involved in the production of a recent Broadway musical. As a culmination of the lesson, students will write a persuasive letter describing the benefits and pitfalls of investing in either non-profit or commercial theatre.
	Math for the Frontier	Grades 3-5
	In this lesson plan, your students will develop their math skills as they examine what supplies were needed to travel to Montana in the 1880s. They'll learn about addition, frontier life, and inflation, all at the same time.
	Cyber Chow Combos	Grades 3-5
	Have your elementary students chow down with these fun combination activities. In this lesson, students are introduced to the concept of using lists and diagrams to understand combinations as illustrated in the CYBERCHASE episode: A DAY AT THE SPA. The lesson culminates with students creating and working with combinations of their own.
	Exploring the Smithsonian	Grades 5-8
	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	Grades 9-12
	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	Grades 7-12
	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?	Grades 7-12
	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!	Grades 7-8
	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.
	Patterns to the Rescue	Grades 3-6
	Have your elementary math students learn the concept of patterns the fun way using Thirteen's CYBERCHASE program and Web site to pull it all together. After students have some fun with the animated series, they find and create their own patterns in their own real environments.
	A Picture is Worth a Thousand Words	Grades 5-8
	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.
	Proof of the Century!	Grades 7-12
	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.
	A Statistical Look at Jewish History	Grades 6-10
	Inspired by the release of the HERITAGE: CIVILIZATION AND THE JEWS dvd, this lesson is designed to complement the students’ study of the history of the Jewish Diaspora. Using population figures from the last hundred years, students can understand the importance of percentages in studying trends and cultural phenomena. Ultimately, students will apply the skills they’ve learned to look at their own ethnic group and figure out how it is represented in the U.S. and around the world. Students will also examine their school community’s ethnic composition and see how it compares to the national figures.
	Understanding Pi	Grades 7-9
	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	Grades 9-12
	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.
	Tracing Math's Evolution	Grades 5-12
	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.
	Women in Math	Grades 9-12
	Students explore the lives and careers of women who have made historic and contemporary contributions to the fields of mathematics and computer science.
