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

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, presen
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
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 form

Graphs (graded)
This week, we begin graphing systems of simultaneous equation. Before we begin looking at the
many graphs you can find out on the Web, let's review our knowledge of 2-D graphs. These
graphs are known as 2-D because they have two axes. One
