PECT PAPA: Numbers & the Number System Chapter Objectives
Prospective teachers in the state of Pennsylvania take the PECT PAPA exam as part of the initial certification process. Taking this computer-based certification exam involves completing three testing modules. One of these modules will test your mathematics skills and consists of 36 multiple-choice questions. This module can be completed in a 75-minute testing session or with the other two modules in a 240-minute testing session. This chapter will help you prepare for questions in the mathematics module that may assess your knowledge of real numbers and number operations.
1. What are Real Numbers? - Definition & Properties
There are many definitions of real numbers, but they all lead to the same conclusion. Real numbers are numbers that have a measurable value. Learn more about real numbers with some examples and a quiz to test your knowledge.
2. What Is a Number Line?
A number line is a visual representation of all real numbers. In this lesson, we'll learn how to identify points on a number line. We'll also practice addition and subtraction, letting the number line do all the hard work.
3. Using the Number Line to Compare Decimals, Fractions, and Whole Numbers
Watch this video lesson to learn how useful the number line can be when you need to compare two different numbers, be they whole numbers, decimals or even fractions. Learn how to plot these numbers on the number line so you can compare them.
4. Relative Magnitude of Numbers: Definition & Examples
Read this lesson to learn how you can go about deciding whether one particular number is greater or lesser than another. Also in this lesson, you'll see how negative numbers seem to go contrary to what you would expect.
