### About This Chapter

## MTEL Mathematics (Elementary): Estimating & Rounding - Chapter Summary

Use the video lessons in this chapter to get reacquainted with estimating and rounding, concepts you will see on the MTEL Mathematics (Elementary) assessment. By exploring entertaining videos, you will have the knowledge to:

- Describe how to estimate in math
- Demonstrate how to round to the nearest 1000, 10,000 and 100,000
- Share how to estimate a difference by rounding
- Explain how to use front-end estimation
- Show the process of rounding decimals and finding the missing digit
- Estimate the sum and difference between two decimals
- Exhibit your ability to round mixed numbers

In addition to watching the video lessons in this chapter, you can access full transcripts with vocabulary words that can deepen your understanding of estimating and rounding. You can easily visit specific portions of the video lessons without watching then in full by using timelines that let you skip to key topics. Self-assessment quizzes are available to test your knowledge of the subject area. Also, access a broader chapter exam to reinforce concepts learned in the lessons.

### 1. How to Estimate in Math: Definition & Concept

Learn how to use estimate values in this lesson. It can help you answer math problems that use more complicated numbers and even make it easier to split a check at the restaurant next time you are out with friends!

### 2. Rounding Numbers to the Nearest 1000, 10,000 & 100,000

After watching this video lesson, you will be able to round larger numbers like a pro. Learn what the cutoff numbers are for rounding up and down to the nearest thousand, ten thousand and hundred thousand.

### 3. 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.

### 4. 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.

### 5. Rounding Decimals & Finding the Missing Digit

After watching this video lesson, you will learn how to round decimals and how to use your knowledge of rounding to help you find a missing digit. Learn what the difference is between rounding decimals and rounding regular numbers.

### 6. 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.

### 7. How to Round Mixed Numbers

After watching this video lesson, you should be able to round mixed numbers easily and quickly. You will learn about what number to look at to determine whether you should round up or round down.
