1. Finding Multiples of Whole Numbers
After watching this video lesson, you will become a pro at finding multiples of whole numbers. Learn what they are and how you can visualize the process to make it easier for you.
2. Finding Factors of Whole Numbers
After watching this video lesson, you will be able to factor any whole number that you are given. You will learn what factors are and how a whole number can have several different factors.
3. Ordering Integers
After viewing this lesson, you should be able to order integers from least to greatest or from greatest to least. Learn how to compare integers so that you can place them in the right location.
4. Comparing and Ordering Fractions
Comparing and ordering fractions is way to examine fractions that contain different-sized sets. In order to compare these fractions, you must find a common denominator and make equivalent fractions.
5. Comparing & Ordering Mixed Numbers
Read this lesson, and you'll learn how you can easily compare and order your mixed numbers. You'll learn how fractions can actually help you to easily see which number is larger or smaller.
6. Identifying Prime & Composite Numbers
In this video lesson, you will learn how to identify both prime and composite numbers. You will also learn what makes the numbers unique, as well as the characteristics of both these types of numbers.
7. How to Round Whole Numbers
View this lesson to learn how you can round whole numbers. Practice rounding to the nearest tens and hundreds. Learn which digit you need to look at to know whether to round up or down.
8. How to Round Decimals
After watching this video lesson, you will be able to look at any decimal number and round it any which way you want. Learn the tipping point that determines whether to go up to the next number or not.
9. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
10. Converting Repeating Decimals into Fractions
After watching this video lesson, you will be able to convert any repeating decimal that you come across into a fraction. Learn how to write the two equations that are needed for the conversion.
