In this episode, students will learn to combine arithmetic and geometry for success in algebra. The coordinate plane is introduced using the example of latitude and longitude, and the identification of points as ordered pairs is examined. Equations of the type y = ax + b are associated with lines, and the significance of the signs of "a" and "b" is discovered. Students will also learn to plot the point associated with an ordered pair and to plot points and draw lines that graph the equation y = ax + b. Grades 3-7. 30 minutes on DVD.
