About The Author AUTHOR REBECCA WINGARD-NELSON has worked in public, private, and home-school mathematics education. She has been involved in various educational math projects, including developing and writing state assessment tests, exit exams, and proficiency tests, as well as writing and editing textbooks and workbooks. Most of the topics that are found on math tests are taught in the classroom.

Paying attention in class, taking good notes, and keeping up with your homework are the best ways to be prepared for tests. Use test preparation materials, such as flash cards and timed worksheets, to practice your basic math skills. Take practice tests. They show the kinds of items that will be on the actual test. They can show you what areas you understand, and what areas you need more practice in. Relax.

Eat a good meal. Go to bed early enough to get a good nights sleep. Dont cram on new material! Review the material you know is going to be on the test. Get what you need ready. Sharpen your pencils, set out things like erasers, a calculator, and any extra materials, like books, protractors, tissues, or cough drops. Get up early enough to eat breakfast and not have to hurry.

Wear something that is comfortable and makes you feel good. Listen to your favorite music. Get to school and class on time. Stay calm. Stay positive. Before you begin, take a deep breath.

Focus on the test, not the people or things around you. Remind yourself to do your best, and not worry about what you do not know. Work through the entire test, but dont spend too much time on any one problem. Dont rush, but move quickly, answering all of the questions you can do easily. Go back a second time and answer the questions that take more time. Read each question completely.

Read all the answer choices. Eliminate answers that are obviously wrong. Read word problems carefully, and decide what the problem is asking. Check each answer to make sure it is reasonable. Estimate numbers to see if your answer makes sense. Concentrate on the test.

Stay focused. If your attention starts to wander, take a short break. Breathe. Relax. Refocus. Dont get upset if you cant answer a question.

Mark it, then come back to it later. When you finish, look back over the entire test. Are all of the questions answered? Check as many problems as you can. Look at your calculations and make sure you have the same answer on the blank as you do on your worksheet. Three common types of test problems are covered in this book: Multiple Choice, Show Your Work, and Explain Your Answer. Tips on how to solve each, as well as common errors to avoid, are also presented.

Knowing what to expect on a test and what is expected of you will have you ready to ace every math test you take.

Multiplication adds the same number over and over. For example, multiplying 4 by 3 is the same as adding 4 three times. (4 3 = 4 + 4 + 4)The cost of a ticket to the junior high dance is $5. What is the cost of three tickets?The problem can be solved in two ways.Use addition: Add the cost of each ticket. Each is $5.

Add $5 three times. $5 + $5 + $5 = $15 Use multiplication: Multiply the cost of each ticket by the number of tickets. $5 3 = $15 factor: A number that is multiplied in a multiplication problem.product: The result of multiplying numbers.factor factor = product

What is the product of 6 and 2? When you can know the answer to a multiple choice question or you can solve it easily, mark the answer. This problem multiplies 6 by 2. A number multiplied by two is the same as adding the number to itself, or doubling it.

Multiple choice questions give you a set of answers.

Multiple choice questions give you a set of answers.

You choose which of the given answers is correct.Memorizing the basic multiplication facts for factors 1 through 12 will help you multiply larger numbers. Some tips can help you memorize the facts.Count By: Any multiplication fact can be found by counting by one of the factors. For 5 3, count by 5 three times: 5, 10, 15. So, 5 3 = 15.Doubles: A number multiplied by 2 is double the original number. For 8 2, double 8 is 16. So, 8 2 = 16.Double-double: A number multiplied by 4 is double-double the original number.

For example, to solve 3 4, first double 3 to 6. Double 6 is 12. So, 3 4 = 12.Add one more: When you know some multiplication facts, you can find others by adding one more. If you know that 11 6 = 66, you can add one more 6 to find 12 6. Since 66 + 6 + 72, then 12 6 = 72.Nines: The digits in the products for the nines multiplication facts from 1 to 10 have a sum of 9. For 9 7 = 63, add the digits in 63: 6 + 3 = 9.Fives: A product of 5 and another number always ends in 0 or 5.

For example, 5 3 = 15 and 5 8 = 40.Even factors: A product of an even number and another number is always even. For example, 4 6 = 24.

Complete the multiplication table. A multiplication table has one set of factors along the top and one set of factors along the left side. Each cell is filled with the product of the factors for that row and column. For each empty cell, find the factor for that row and multiply it by the factor for that column. For example, the cell with the red circle has a row factor of 2 and a column factor of 3.

You may need to fill in a blank or you may need to show how you got your answer.

power of ten: A number that begins with a one and is followed by zeros. The numbers 10, 100, and 1,000 are powers of ten. Powers of ten are products of 10 multiplied by itself. 10 to the third power is 10 10 10 = 1,000.multiples of ten: Products of 10 multiplied by another number. The number 80 is a multiple of ten because 10 8 = 80. All multiples of ten end in a zero.Multiply 6 by 10, 100, and 1,000.Step 1: To find the product of a power of ten and another number, add the same number of zeros to the other factor as there are in the power of ten.

To multiply by 10, add one zero. = To multiply by 100, add two zeros. = To multiply by 1,000, add three zeros.
