Addition
Addition is one of the fundamental operations performed in everyday life.
See addition worksheets 
Algebra
Algebra is where letters, numbers, and symbols are given a purpose in math operations.
See algebra worksheets 
Basic Operations
These worksheets and lessons focus on the four fundamental math operations.
See basic operations worksheets 
Comparisons
We not only compare and order integers, but we also compare data on a graph.
See comparison worksheets 
Complex Numbers
These are a combination of real and imaginary numbers. You will be able to spot both distinct parts.
See Complex Numbers 
Coordinate Graphing
We work on plotting sets of ordered pairs and making sense of their location.
View Coordinate Graphing 
Counting
When we have a set group, this is the way we learn to order the set and create a system.
View Counting 
Exponents
This concept tells us how many times a value needs to be multiplied by itself based on the power it is raised to.
View Exponents 
Factoring / Multiples
We look a two very different by directly related concepts in this section.
View Factoring / Multiples 
Fractions
We learn how to represent a part of a whole value. We understand how to break it into smaller portions.
View Fractions 
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.
View Integers 
Irrational Numbers
These are values that you cannot write as a simple fraction. They are a bit crazy!
View Irrational Numbers 
Linear Equations
This is where geometry and algebra start to overlap a bit. We work with equations of the line.
View Linear Equations 
Logarithms
These seem very complex, but it simply helps you determine how many times you must multiply a number to get a set value.
View Logarithms 
Measurement
We use a variety of tools and techniques to learn to quantify something so that we can understand it better.
View Measurement 
Metric System
Introduced to the world in the late seventeenth century, this system of measurement is used by most of the world today.
View Metric System 
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.
View Multiplication 
Order of Operations
We learn which math operation you should use at what time when you are confronted with multiple operations to process.
View Order of Operations 
Patterns, Sequences
Students learn how to breakdown a system and determine which rules are followed to produce it.
View Patterns, Sequences 
Percentages
The is a ratio of a whole or full value expressed as a fraction of 100.
View Percentages 
Place Value
We begin to look at the specific value of digits that are found within values.
View Place Value 
Polynomials
We explore these many termed expressions. Students learn how to manipulate the constants, variables, and exponents that they are composed of.
View Polynomials 
PreCalculus
This is a later High School subject that is making sure you are ready for advanced college math.
View PreCalculus 
Probability
What is the likelihood that something will take place under the given conditions?
View Probability 
Quadratic Equations
When graphed, they make nice curves. We break down the anatomy of these types of equations and learn to manipulate them.
View Quadratic Equations 
Ratios & Proportions
These are often thought as one in the same, but they are not.
View Ratios & Proportions 
Scientific Notation
A very helpful way to name values that are either very large or very small.
View Scientific Notation 
Shapes
We look at the simple geometric uses of shapes and help give them more meaning to you.
View Shapes 
Statistics
This is a varied series of ways we approach data to help us make better and more informed decisions.
View Statistics 
Subtraction
We learn to find the difference between many different types of values.
View Subtraction 
Time Math
We learn how to make sense of all types of things that are related to time.
View Time Math 
Word Problems
Students will explore problems that are presented as a story and relate to all different applications of math.
