Addition is one of the fundamental operations performed in everyday life.

• ### Algebra

Algebra is where letters, numbers, and symbols are given a purpose in math operations.

• ### Basic Operations

These worksheets and lessons focus on the four fundamental math operations.

• ### Comparisons

We not only compare and order integers, but we also compare data on a graph.

• ### Complex Numbers

These are a combination of real and imaginary numbers. You will be able to spot both distinct parts.

• ### Coordinate Graphing

We work on plotting sets of ordered pairs and making sense of their location.

• ### Counting

When we have a set group, this is the way we learn to order the set and create a system.

• ### Decimals

The concept of base ten allows for a fun way to denote mathematical values.

• ### Division

Students will get an opportunity to with simple and long forms.

• ### Estimation

For times when you just need to have a general sense of the value.

• ### Exponents

This concept tells us how many times a value needs to be multiplied by itself based on the power it is raised to.

• ### Factoring / Multiples

We look a two very different by directly related concepts in this section.

• ### Fractions

We learn how to represent a part of a whole value. We understand how to break it into smaller portions.

• ### Geometry

One of the oldest forms of mathematics that explores size, shape, and the position of things.

• ### Graphing and Data

These awesome graphical displays allow us to bring our data to life and help us make good decisions.

• ### Integers

This is one of those terms that are loosely thrown around, but often students do not fully understand it.

• ### Irrational Numbers

These are values that you cannot write as a simple fraction. They are a bit crazy!

• ### Linear Equations

This is where geometry and algebra start to overlap a bit. We work with equations of the line.

• ### Logarithms

These seem very complex, but it simply helps you determine how many times you must multiply a number to get a set value.

• ### Logic

In math we use this to determine the validity of a math statement or sentence.

• ### Matrices

We learn how to use and manipulate an array of numbers.

• ### Measurement

We use a variety of tools and techniques to learn to quantify something so that we can understand it better.

• ### Metric System

Introduced to the world in the late seventeenth century, this system of measurement is used by most of the world today.

• ### Money

We start by counting it and then we see how they can be applied to complex systems.

• ### Multiplication

It is time to really see what we can do with the form of addition on Mountain Dew.

• ### Order of Operations

We learn which math operation you should use at what time when you are confronted with multiple operations to process.

• ### Patterns, Sequences

Students learn how to breakdown a system and determine which rules are followed to produce it.

• ### Percentages

The is a ratio of a whole or full value expressed as a fraction of 100.

• ### Place Value

We begin to look at the specific value of digits that are found within values.

• ### Polynomials

We explore these many termed expressions. Students learn how to manipulate the constants, variables, and exponents that they are composed of.

• ### Pre-Calculus

This is a later High School subject that is making sure you are ready for advanced college math.

• ### Probability

What is the likelihood that something will take place under the given conditions?

When graphed, they make nice curves. We break down the anatomy of these types of equations and learn to manipulate them.

• ### Ratios & Proportions

These are often thought as one in the same, but they are not.

• ### Rounding

We learn how to form values into an approximate value.

• ### Scientific Notation

A very helpful way to name values that are either very large or very small.

• ### Shapes

We look at the simple geometric uses of shapes and help give them more meaning to you.

• ### Statistics

This is a varied series of ways we approach data to help us make better and more informed decisions.

• ### Subtraction

We learn to find the difference between many different types of values.

• ### Time Math

We learn how to make sense of all types of things that are related to time.

• ### Trigonometry

A subject area that is completely obsessed with right triangles.

• ### Word Problems

Students will explore problems that are presented as a story and relate to all different applications of math.
