# Ch 8: MTEL Math: Estimation

### About This Chapter

## MTEL Math: Estimation - Chapter Summary

This chapter will address estimation in mathematics as a part of your studies for the MTEL Math exam. In these lessons you will learn how estimation can be used for the following:

- Determining a difference by rounding
- Estimating sums using front-end estimation
- Solving sums and differences between two decimals

As you study these lessons you will be led by expert instructors who aim to explain the information clearly and concisely. If you have any difficulties with the content of any of these brief video lessons, you may submit your questions to our expert mathematicians.

### MTEL Math: Estimation - Chapter Objectives

Part of the process to attain your license to teach mathematics in Massachusetts, the MTEL Math exam is meant to assess your knowledge of various math skills. Of the exam's 100 multiple-choice questions and 2 open-response items, 12% are focused on testing your knowledge of numbers and operations. Your abilities of estimation may be tested within this 12% of the exam, so a careful review of this chapter's content should help prepare you for any related questions you may be asked. These lessons will teach you how to estimate, and if you take the self-assessment quizzes provided you will have the opportunity to practice answering questions in the same multiple-choice format as the MTEL Math exam.

### 1. Estimating a Difference by Rounding

After studying this lesson, you will understand rounding basics. You'll also learn how to quickly solve subtraction problems by using your rounding skills.

### 2. How to Use Front-End Estimation

In this video lesson, you will learn how to estimate addition and subtraction problems by using the method of front end estimation. Learn what is involved and what you need to be careful of.

### 3. Estimating the Sum & Difference Between Two Decimals

In this video lesson, you will learn how to take an addition or subtraction problem with decimals and estimate the answer by rounding. You will learn that a rounded answer is very close to the actual answer.
