Fractions in Everyday Life (graded)

Fractions and mixed numbers are often used in everyday life. Discuss a real-life example in which you would need to add, subtract, multiply, or divide fractions or mixed numbers, and show the math.

Algebra Concepts (graded)

Communication is considered an important component of mathematics education in order for deep learning to occur. Choose a specific algebra concept that you think you understand well, and explain it in your own words. Then, present a math problem for your classmates to solve, making use of this concept.

Let's Look at Ratios (graded)

Did you drive to work today? If you did, you used a ratio. Driving 30 miles per hour involves a ratio or proportion of two numbers. It can be written as a fraction, (30 miles)/(1 hour), or the way we most commonly see it: 30 mph. Let’s start the discussion this week by identifying other proportions we see in our everyday lives. Think of an example of a proportion you use in your life. List the proportion, explain its meaning, and don’t forget to include its fraction equivalent.

Understanding Equations (graded)

Being successful in mathematics requires understanding as opposed to simple memorization. For example, the formula to find the perimeter of a rectangle is P = 2L + 2W (where L is length and W is width). Memorizing the formula could be helpful, but if we understand that the perimeter is the distance around the rectangle, we are able to construct the formula and apply it to real-world situations correctly.

Find another formula that you use in your daily life, and explain the meaning behind it. Then, look at one of your classmate’s formulas and see if you agree with your classmate’s interpretation of its meaning.

For example, the formula to calculate sales tax on a purchase is sales tax = 0.0825x. The coefficient, 0.0825, is the current tax rate of 8.25%. The variable, x, is the amount of your purchase.

Linear Relationships (graded)

Did you drive to work or school today? When you are driving at a constant speed, the amount of gas left in the tank can typically be modeled by a linear equation. The equation y = -2x + 15 would represent a car that has a full 15-gallon tank and burns 2 gallons of gas an hour when x is the number of hours driven and y is the amount of gas in the tank. Find a linear relationship (equation) that you would use or rely on in your field when you receive your degree, and explain what it is and how it is used. Identify the initial condition, such as the full tank of gas above, and the rate of change. For a linear equation, the rate of change (slope) needs to be constant. If you can’t find one in your field, broaden your research to include any real-world application.

Exponents and Polynomials in the Real World (graded)

Have you ever seen a semi truck with a curved truck bed rather than a flat one? Why are most lenses curved? These are just a few examples in which we have real-world examples that make use of exponents and polynomials. Research common applications of exponents (don’t limit yourself to physics; check business, finance, and the medical world for examples, as well), and post what you find here. You may also post explanations of vocabulary found in this section, and explain why it is important. Be sure your posts are unique and not just repetitions of what someone else has already submitted.

Problem Solving and Success Strategies (graded)

How do you prepare for a post-test? What is the learning strategy that you use? In the homework, you can rely heavily on the view an example and the help me solve this features. Do those help you learn the material well enough to be successful on the post-test? Do you spend a lot of time with the course or publisher videos? Is the extra practice the most helpful? What strategy have you found so far that works, and is there anything that you would recommend someone new to this course avoid doing or relying solely upon?
