Number lines are great ways to represent a group of numbers, and in this tutorial you'll see how to graph a group of numbers on a number line
How Do You Plot Points in the Coordinate Plane?

Knowing how to plot ordered pairs is an essential part of graphing functions. In this tutorial, you'll see how to take an ordered pair and plot it on the coordinate plane. Take a look!
What is an Ordered Pair?

Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!
What is the Coordinate Plane?

You can't graph a function or plot ordered pairs without a coordinate plane! Learn about the coordinate plane by watching this tutorial.
What are Quadrants in the Coordinate Plane?

Did you know that there are four quadrants that help make up the coordinate plane? Learn about these quadrants, and what ordered pairs are located in each, by watching this tutorial!
How Do You Compare Two Decimals Using a Number Line?

If you have two decimals and you want to know which is larger, you can use a number line to help you compare! Follow along with this tutorial to see how to use a number line to compare decimals.

How Do You Compare Integers Using a Number Line?

Trying to figure out if a negative number is larger than another can be a little tricky. To make things easier, you could use a number line! This tutorial shows you how to use a number line to compare two negative numbers and determine which is larger.
What is the Opposite, or Additive Inverse, of a Number?

Have you ever combined two numbers together and found their sum to be zero? When that happens, those numbers are called additive inverses of each other! In this tutorial, you'll learn the definition for additive inverse and see examples of how to find the additive inverse of a given value.
What are Positive and Negative Numbers?

Positive and negative numbers (and zero!) are the building blocks of math. This tutorial will introduce you to positive and negative numbers and show you their location on a number line. Plus, learn a special thing about the number zero!
What is the Number Line?

A number line is a way we can visually represent numbers. This tutorial gives you a great introduction to the number line and shows you how to graph numbers on the number line in order to compare them. Check it out!
How Do You Put Fractions and Decimals in Order?

Ordering numbers from least to greatest? Are the numbers in different forms? To make comparing easier, convert all the numbers to decimals. Then, plot those decimals on a number line and compare them! This tutorial shows you how!
