As part of a study guide course for the Massachusetts Tests for Educator Licensure (MTEL) Mathematics/Science (Middle School) exam, these short, engaging and mobile-device friendly lesson videos outline different number systems and arithmetic operations. These lessons are taught by our expert instructors who are available to answer any questions you may have about these topics so that you can master material about:

  • Whole number place values
  • Addition, subtraction, multiplication and division with whole numbers
  • The base-ten system and other number systems
  • Differences between prime and composite numbers
  • Uses for number lines
  • Factoring and prime factorization of numbers
  • Divisibility rules
  • Roman numerals and other ancient number systems

Study these lessons at a fast pace or a leisurely one, depending on your current schedule. You can use the pause and skip features of the videos to focus on the topics you want to learn more about. Corresponding transcripts provide another way of studying, and they include bold terms that you'll need to know. The lessons are followed up by short quizzes.

MTEL Middle School Math/Science: Number Structure Chapter Objectives

The purpose of the MTEL Mathematics/Science (Middle School) is to ensure that future middle-grades math and science teachers have the mathematics and science knowledge required to teach their future students. When you take this computer-based certification exam, you will be asked to complete 100 multiple-choice questions and two open-response assignments within about four hours. Eight percent of your score for this exam will be determined based upon your knowledge of number sense and operations. Improve your understanding of these topics by watching the lessons of this chapter and reviewing the different numeric structures, systems and operations.
