Bring in cookies and talk about how ratio and concept is used in our everyday life. It is used when we plan a party, when we determine how much gas we can put in our car, or how much paint will be needed when painting our home.

Ratio is when you are comparing two numbers and there are three ways it can be written. 3 to 2, 3/2, or 3:2

Remember to write the ratio in the order given in the order given in the problem.

]]>It is the fee that a person pays for the use of someone else’s money. This type of interest is called simple interest and there is a simple formula for finding it.

simple interest = principle x rate x time

This is an important GED math concept to understand and practice. Be sure to always change the percent to a decimal before multiplying (i.e. 6% = .06). Also remember that time is based on years. So, if the time is 2 years you multiply by 2, but if the time is 6 months you multiply by 6/12 or 0.5 because it is a half a year.

]]>If you remember some simple key ideas, and practice a variety of problems, it will be easier to solve quickly on the GED math test.

- Determine the amount of change. The amount of change is the difference between the new number and the original number.
- Divide the amount of change by the original number. This will result in a decimal number.
- Change the decimal number to a percent.
- Remember that percent of increase CAN be greater than 100%.

]]>New number – original number/ original number = decimal number = percentage of increase or decrease.

Cost formula

total cost = (number of units ) x (price per unit)

It is also important to be able to use this formula to determine the number of units or the price per unit.

total cost / number of units = price per unit

total cost / price per unit = number of units

Because this formula can be used in a variety of ways, it is important that when you solve a GED math problem you read the problem carefully and substitute the values back into the formula. Also be aware that if there is extra important information, you include that as well.

What better way to practice this formula than to show students a real life application. Not everyone will need to fix their driveway, but it may apply to many students… especially those in rural areas were gravel driveways are popular.

This problem will give students an opportunity to explore this cost formula as well as algebraically set this problem to be solved.

One could also explore the cost per gallon of gas, cost of a single egg in a dozen, or cost comparison when looking at meat at a grocery deli.

Whatever you choose, your students will benefit not just for the test… but for days months years to come.

]]>As I thought about it, I realized that this would be a great real-life math problem. Especially for GED students learning about math. What a great example to discuss comparison and percent using critical thinking skills.

Let’s explore this situation and see what the results are. Is this something you would try in your classroom?

When I researched the calorie and nutritional value of raw carrots, I learned that 1 cup of carrots is about 50 calories. Besides being low in calories, it is HIGH in nutrients. For a complete list, check out whfoods. I was especially surprised that 1 cup contains 113 % of our needed vitamin A. And let’s not forget the fiber, 3.1 grams per cup.

When I researched raw cucumbers, I learned that 1 cup of raw cut up cucumbers has only 16 calories as well as .83 gram of fiber per cup and a lot of nutrients, the highest being 19% of vitamin K. For a compete list, check out whfoods.

If you like to dip your veggies in Ranch dressing (like we do), you will need to add 70 calories per tablespoon. Delicious… but not very nutritious.

For each veggie bag, I figured there was about 1/2 cup carrots and 2/3 cup cucumbers as well as a container with 2 tablespoons Ranch dressing. So that would be carrots (25 calories), cucumbers (about 5 calories), and Ranch dressing (140 calories) for a total of 175 calories packed with a good amount of nutrients.

Potato chips on the other hand have a 150 calories for 15 chips. Who eats 15 chips? Not me. you may as well double the amount. That would be 300 calories with a whopping 32% daily fat and only 10% fiber (1 gram). I was surprised that the chips I chose contained 20% vitamin C (10% per serving)

*A veggie bag at 175 calories versus a bag with chips (two servings because who just eats one) at 300 calories. If the dressing is left out, the veggie bag would only be 30 calories!!

*Carrots are HIGH in nutrients and fiber.

**What math problems might one do with this information?**

*Difference in calories

*Order carrots, cucumbers, and chips based on fiber, fat, calories, etc.

*Change fractions to decimals

*Percentage of difference

*Check out links and look at nutrients and the difference in foods

*What if a different salad dressing were used? How much of a difference would that make?

If I was able to get 15 veggie bags from the produce bought at the Farmer’s Market, how much would each bag cost?

This is a great problem to teach cost per unit. It could be set up several different ways depending on what math is being taught at the time.

Bring the vegetables to class to have a hands on lesson while enjoying a healthy delicious snack!

]]>It can be a bit overwhelming for students who have not focused on math in awhile, and some can get discouraged. But, I tell them that their “life experience” will help them and they will be surprised at how much they really do know. I do recommend that students get some instruction using a good GED math book. This can be sitting down with a tutor, or perhaps working with an instructor in a learning center. I also recommend that students take an “official practice GED test” which is offered through the GED Testing Service. One does have to pay for them, but many programs and learning centers have vouchers so students do not have to pay for them. I suggest that you check with your local literacy council or adult learning center. There are many resources on this site that will assist you on your journey. If there is something you need…. but do not see…. please comment below. I will do my best to assist.

Knowing your multiplication facts is an important foundation to all areas of math. Unless you know how to multiply, you will have a difficult time with fractions, decimals, percents, algebra, and geometry. It is necessary for preparing for the GED math test.

Download the following multiplication math fact self correcting pre-test. Have your student or child take the test…. then highlight the math table to show which math fact problems were wrong. It is a great visual tool that will allow your child or student to know exactly which multiplication math fact problems they should focus on.

Depending on the age of the student, you can adjust the amount of time given for the assessment.

]]>Many learners, both children and adults, have difficulty learning certain multiplication facts. When I meet with them the first time, I typically hear something like, ” I don’t like math.” or ” It don’t understand math.” And they will tell me that they do not know their math facts. What they do not realize is that they know quite a few of their math facts, not all, but many.

If they are working on their multiplication, I will first have them take my math multiplication facts self correcting test. This will SHOW them just how much they DO know.

If they do not know all of their basic math multiplying by nine facts, I will then show them strategies so they can. There are many great websites which do, but one of my favorites is About.com They have short videos on three Tricks for Multiplying by Nine. These strategies, or tricks as they are sometimes called, are also great for anyone looking to learn GED math.
