  Math Help for the THEA or ACCUPLACER Test

WTAMU > Virtual Math Lab > THEA/ACCUPLACER Introduction

If you need help in preparing for the math part of the THEA or ACCUPLACER test, you have come to the right place.  Note that you do not have to be a student at WTAMU to use this study session.  It was created as a service to anyone who needs help getting ready for this test.

Special note to those taking the math part of the ACCUPLACER test:

 Even though I refer to the THEA test throughout this webpage, if you are planning to take the ACCUPLACER test this page can also help you.  The content of the math part of the THEA and the ACCUPLACER tests are similar, they just may be labeled differently. I believe that if you have the mathematical concepts down, then you should be able to answer a wide variety of questions that use those concepts no matter how the questions are asked.

If this is your first visit to our website, please read the disclaimer.

The math part of the THEA test is split into four main areas:

Below are the specific concepts you need to know about each of those areas.   This list was compiled from researching the Mathematics Skill Descriptions webpage at the official THEA website created by the National Evaluation Systems.

Under each specific concept, you will find links to in-depth tutorials that will help learn and review the material.  These tutorials come from the WTAMU Virtual Math Lab, which I created.  Within these tutorials, you will find pertinent definitions, formulas, step-by-step explanations, an answer/discussion section with step-by-step solutions, and links to other credible webpages that can help you further with that topic.

In math, when you study a specific topic, a lot of times you are incorporating other mathematical topics into solving the problem.  Some of the tutorials will overlap each other.  This will help reinforce the concepts you need to know for the THEA test.

HOW TO EFFECTIVELY USE THIS WEBPAGE:

 Under the Fundamental Mathematics, Geometry and Problem Solving areas, you need to go to all the links that are under each topic to get the full benefit.  Under the Algebra area, there is a lot of overlapping between the different levels (beginning and  intermediate) of tutorials.  Find the algebra level that agrees with you most and do all of the tutorials under that level.  If you start at the beginning level algebra, make sure that you make your way up through intermediate algebra before you take the THEA or ACCUPLACER test. When you are done with a tutorial, you can come back to this webpage by clicking on the back arrow link marked THEA Math Help Page found on the top left corner of the tutorial page OR clicking on the back arrow on the top left of your Internet window until you are back to this page. Fundamental Mathematics

The first area that we will be looking at is fundamental mathematics.  You know, fun things like making sure you have the negative in the right place and remembering when you have to find the common denominator of your fractions.  Don't worry, I have the utmost confidence that you will do much better with arithmetic than Calvin.

 You need to go to all the links that are under each topic for fundamental mathematics to get the full benefit.

The fundamental mathematics area covers:

It's back!!!!!!   Just when you thought it was safe to come back to school, POW, another math test with ALGEBRA!!!  I'm hoping that with this section of tutorials, I will convert some of you who are math atheists (you know who you are).

SPECIAL NOTE:

 Note that most of the topics under Algebra contain tutorials from two levels (lowest to highest): beginning and intermediate.  Ideally, for the Algebra section, you want to be able to work the intermediate level by the time you take the THEA test.  There will be some overlapping between the levels.  If a topic has tutorials in more than one level, try going under the highest level first.  If that is too hard for you, go to the tutorials of the next level down, if available.   Once you find a level to start with, make sure that if it is beginning algebra, in the end you work your way up to intermediate algebra.

The beauty of this is it is individualized.  You can go at your own pace at the comfort of your own computer.  You know better than anyone else what your algebra skills are.
