]]>Welcome to Worksheetsdirect. I hope you will find HISET, TASC and GED help so that you can pass the GED Math test. This is also a great site to help learn basic and intermediate math skills. Explore the site and download free printable GED math worksheets as well as view easy math videos. I have also put together a course on Learning Fractions. If you like the site and find it useful, share it with your friends and colleagues, or simply give a G+. I have been told it is a useful tutoring resource for students of any age.

Having a basic and many times deeper understanding of math is essential. Math is something we use every day and like it or not…. everyone needs to have an understanding of basic algebra, basic geometry, fractions, decimals, and percents. It is also essential to know your basic math facts. Finding resources can sometimes be a challenge, especially if you homeschool or you are providing GED math help.

I teach them how to find the slope with two given points. Unless the points are given to them, they should identify two points on the line. Next, they should label their points y1, y2, x1, x2, keeping each label with its corresponding pair. and then plug them into the point slope formula. y = mx + b

I also teach them how to look at a coordinate grid that already has a line on it and identify slope using the rise/run method. Identify a point on the line, rise up and then run over to the next point.

I teach them how to look at an equation in the slope intercept form and identify the slope and y-intercept. From that information, they can also draw the line on a coordinate grid. If the equation is not in the correct form, go through as many examples as necessary until they “get’ it.

Finally, find some real life examples of using slope so that they understand the need to learn this skill. For example, if a person needs to connect a ramp to their home to make it wheel chair accessible, the slope of the ramp is important.

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!
