In this video, the instructor goes through the steps needed to graph a system of linear inequalities. He discusses slope, shows how to draw the line on the coordinate plane, and explains what section of the graph should be shaded. There is some shadow on the white board which makes it a little more difficult to see at times during the instruction. (04:49)

In this video, the instructor gives directions on how to find a solution for a system of linear inequalities. He provides an example, then goes through the steps to find the solution that satisfies both inequalities. There is a mistake at the beginning of the lesson which the instructor corrects with some text on the screen. (05:17)

A series of portraits of teaching shows how six teachers from across the country are working to revamp their teaching and their schools, and are struggling against a variety of obstacles that might thwart their efforts. These teachers are working to undo the myths about learning inherent in their school systems, and are truly the heroes who will shape our children’s future for life in the Information Age.

early work on problems that engage students in creating notation
systems might open up for students as they move on toward algebra.

Rob Cuddi, a fifth–grade teacher at Winthrop Middle School in Winthrop, Massachusetts, has been teaching for almost 30 years and has recently taken an active role in restructuring the social studies curriculum to accommodate both state and national standards. Mr. Cuddi’s lesson introduces the theme of exploration in North America, posing three essential questions: How have people in history affected our lives today?; How do the human and physical systems of the Earth interact?; and What role do economies play in the foundation of our history?

This program discusses the chemistry of the wonders of life. It starts off with the way life began, and goes on to deal with the structure and function of biological molecules. It emphasizes the value of relating chemical principles to biology studies, and states that living organisms are huge chemical systems in equilibrium. Thus, learning processes are based on the chemistry of life, and this program shows how effective classroom strategies aim at enhanced learning.

Ocean systems operate on a range of scales, from massive systems such as El Niño that affects weather across the globe to tiny photosynthetic organisms near the ocean surface that take in large amounts of carbon dioxide. This program looks at how ocean systems regulate themselves and thus help maintain the planet's habitability.

This program introduces the three sets of investigations that are featured in the Journey North program: Seasonal Migrations, Plants and the Seasons and Sunlight and the Seasons. Seasonal change is all around us. Children see it in the length of a day, in the appearance of a flower, in the flight of a butterfly. Journey North is a free, Internet-based program that explores the interrelated aspects of seasonal change. Through interrelated investigations, students discover that sunlight drives all living systems and they learn about the dynamic ecosystem that surrounds and connects them.
