Passing the GED Math Test

2011-12-27T12:07:00.000-08:00

I often get calls from adult GED students wondering what they should study so that they can pass the GED Math Test. These are typically students who are looking to prepare at home with limited time and resources. They may not have the means (vehicle) to get to a GED Study Center or the money to purchase a GED book. They are ready to start but do not know where to begin.

I will first gently inform them that they need to have a good grasp on the basics of whole numbers, fractions, decimals, percents, basic algebra, and basic geometry. This alone can be daunting for some students because they may not even know their basic facts of adding, subtracting, multiplying, or dividing.

Next, I let them know that the GED math test is mostly application. They will need to be able to read the GED Math problem, pull out important words and phrases, set up the problem, and solve it. Many problems are multiple choice, but many will have you find the exact answer and then record it in a bubble chart.

I let them know that they are NOT alone when it comes to needing guidance in GED math preparation. It has been my experience that most students benefit from at least some instruction. Getting a good GED book from their local library, help from a friend, or instruction from a GED tutor/teacher will all help.

Finally, lets not forget about patience! Students want to learn it and they want to learn it now! And... when some learn new information, they may not be patient with themselves when it takes a bit longer to retain it. Remind them that they may need to hear it more than once to remember it.... and that is OK!

Mean is the average of a group of numbers. To find the mean of a group of numbers you first add all the numbers together. You then divide by the number of elements you have in the data set. Let's try an example. Data set: 3, 5, 9, 8, 10 Number of elements: 5 Mean = (3 + 5 +9 + 8 + 10)/5 = 7 Now you can try an example. Data set: 6, 7, 8 11, 15, 7, 23 What is the data set? How many elements? What is the mean? Answer coming shortly.

GED Math Help: Simple Interest = PRT

The formula for finding simple interest is Principal x rate x time. One key concept is to remember that time is based on 1 year. Therefore, if the time is 5 years, you multiply by 5. However, if the time is 6 months, you multiply by 0.5 because 6 months is 1/2 of a year.

Lets try out this formula. Lets say that you are borrowing $1000 for 3 years at 5% interest. How much interest would you earn?

I = 1000 * 0.05 * 3 You would earn $150.00

Lets try another example. You are purchasing a car for $12,500 and will be taking out a 5 year loan at 3%. What will be the TOTAL cost (car plus interest)?

12,500*0.03 * 5 = $1875

To find the total cost, you should add the interest to the original principal.

$12,500 + $1875 = $14375

GED Math: Simplifying Algebra Expressions Disributive Property

I have found that one of the most difficult math concepts for GED students to understand and grasp is the concept of combining like terms, expecially those involving the Disributive Property.

I am beginning to understand that unless the learner has an almost perfect understanding of adding, subtracting, multiplying, and dividing integers (positive & negative), the process of simplifying expressions, along with the Distributive Property, is very difficult.

Students also need to have their basic math facts memorized. Many will come in understanding and knowing the basic facts of adding and subtracting. But when asked to multiply and divide.... that can be more challenging. Have them practice their facts, outside of class, using worksheets.

Even with a good grasp of integers and basic math facts, most students will need to take the concepts of the distributive property, combining like terms, and solving expressions one step at a time.

One important method is to teach a "small learning concept" and then give them a LOT of practice. For example, I taught the distribute property and went through about 7 examples. I then followed up with a worksheet containing 20 more examples! Although it seems like alot, and perhaps you might think way too much..... my students want the extra practice.

Once they understand the Distributive Property, I will then proceed and teach the combining of like terms. Here again, it will take a LOT of examples..... followed by a worksheet.

Susan is planning on attending college. The tuition including room and board is $15, 423.00 for the school year. If she receives $9, 420.00 in assistance, how much does she still need to pay? What percentage of the total cost will she need to pay?

Solution: This problem is asking for two answers. To answer the first question, you need to take the total tuition and subtract the assistance. $15, 423.00 - $9420.00 = $6003.00

Susan will need to pay $6003.00.

To answer the second question (what percentage of the total tuition will Susan pay), you need to translate it into a question, then solve.

$6003.00 is what percentage of $15, 423.00?

$6003.00 = Wp x $15, 423.00

$6003.00 ÷ $15, 423.00 = 0.3892 which is 38.92%

Susan will need to come up with almost 40% of the cost of tuition.

Perimeter = side x 4

Perimeter = 6 in. x 4

Perimeter = 24 inches

Anna works in a clothing store and receives a 20% employee discount. If Anna decides to buy a $120 coat, what will her total cost be with 5.5% tax.

solution: In order to solve this problem you must first calculate Anna's 20% discount. Hint: Change the 20% into a decimal. Next, subtract the discount fromthe origional price, this gives you Anna's sale price. Calculate the sales tax, again by changing the percent into a decimal. Finally, add the sale price and sales tax together.

$120 x .2 = $24 (discount)
$120 - $24 = $96
$96 x .055 = $5.28

Do you understand the number pattern for Pascual's Triangle? If you don't, you are not alone. Up until now, every time I saw it... I had to think about it. And then, I still may not have figured it out... or should I say remembered what the pattern was.

That is, up until now.

The pattern: Each number is just the two numbers above it, added together.

Can you figure out what the next row will be?

GED Math Help: percents

To rent a hall for a party reception (for 1 evening) costs $225. The Hall is also charging $25.50 per adult and $19.95 per child for the meal and reception. Gratuity is 15% of total costs. If 125 adults and 32 children attending the party, what is the total cost.... including gratuity?

Answer: Set up the problem as follows:

First part: (cost of hall + (cost of adult meal)(number of adults attending)+ (cost of child meal)(number of children attending)
Second part: 15% of (cost of hall + (cost of adult meal)(number of adults attending)+ (cost of child meal)(number of children attending)
.
Find the answers to part one and two, and then add them together.
.
Part one- hall and meals: $225 + (125 x $25.50) + (32 x $19.95) = $4050.90.
Part two- gratutity: .15 x $4050.90 = $607.34
.
Total cost: $4050.90 + $607.34 = $4658.24

GED Skill: Simple Interest

Pamela is taking out a car loan for $12,500 at 6.75% interest for 7 years. How much interest will she pay and how much will her monthly payments be ?
Answer: To find out how much interest Pamela will pay, use the simple interest formula of principal x interest x time: $12,000 x .0675 x 7 = $5670. WOW that's a lot!

To find out how much her monthly payments will be, add the principal and interest ($12,000 + $5670 = $17,670) and divide it by the total months (12 months x 7 years = 84). Finally, divide $17,670 and 84. The monthly payment will be $210.36.

Percents: GED Skill

Karen bought a new sweater for 20% off the original price. If the original price was $49.99 and sales tax is 5.5%, how much did Karen spend on her new sweater?

Answer: First you need to find the actual cost of the sweater (original price minus the 20% off). Take $49.99 x .2 which equals $9.99. $49.99 - $9.99= $40.00 (cost of sweater on sale). Second you need to calculate sales tax (5.5%) on $40.00. Take $40.00 x .055 which equals $2.20.

Finally, you need to add the cost of the sweater, $40.00, and the cost of the sales tax, $2.20 together. $40.00 + $2.20 = $42.20

The answer is $42.20.
