Number Line, The: Introduction to the Number Line
This clip explains the concept of the number line, a kind of road map on which every whole number has a corresponding point. The points are in order, just like the numbers, and the distances between them are equal.
Number Line, The: Inequalities on the Number Line
This clip demonstrates how "less than" and "greater than" look on the number line. We learn that with any two whole numbers that are not equal, the greater number will always appear on the right, and the smaller number always appears on the left.
Using Two Points on a Line to Write an Equation
Using the coordinates of two points on a line to write an equation involving the Celsius and Fahrenheit temperature scales.
