The teacher diagrams a coordinate plane and identifies the four quadrants. He labels the quadrants with numbers. Then he illustrates a table to identify the positive or negative value of the x-coordinate and the y-coordinate and...

The rate of change is defined as how one quantity changes in relationship to another quantity. The instructor diagrams a graph and demonstrates how to use a formula to calculate the rate of change. It might take two viewings to catch all...

You have a slope and a given point and now you have to graph it. Begin by drawing a graph and then plotting the given point. Remember that slope is rise over run. So, from the given point move the appropriate spaces to plot the next...

Have your class watch this video to get a better understanding of adding and subtracting positive and negative numbers. In an easy to understand manner, the presenter explains how to add numbers, both negative and positive, using a...

If your class is studying inequalities, consider this video. The focus is on solving a decimal inequality that has negative numbers in it. A lecturer works through an example problem, commenting on the steps and properties necessary to...

Break down integers with this video. A teacher gives a basic definition and provides several examples of integers. The examples cover numbers that are integers as well as numbers that are not integers. A concise video, this resource...

Help your learners grasp inequalities with this video. A lecturer leads viewers through solving an inequality by multiplying by a negative number, citing the multiplication property of inequality and finishing with set notation. This is...

With an enthusiastic instructor who writes clear steps on a whiteboard, this video demonstrates how to solve an inequality by dividing by a negative number. What makes this video stronger is the second part of the video, in which the...

Draw a graph, label your units, make a table of your given coordinates. Now plot your points, label each point as you graph it. Next identify the quadrant that each point is in and add that to your table.

You have a slope and a given point and now you have to graph it. Begin by drawing a graph and then plotting the given point. Remember that slope is rise over run. So from the given point move the appropriate spaces to plot the next...

How can two negative values create a positive slope? Rise over run, a negative divided by a negative. Watch the instructor explain just how that works.

Rise over run? The instructor explains two ways that a slope can be negative. It's not as complicated as you may think. Follow along on this lesson and see for yourself.

Clear up the confusion surrounding division of negative numbers with this short video. Viewers will learn how to determine if the answer to an integer problem is going to be negative or positive, and they'll witness the tutor work...

Use a number line to plot the given points to compare their value. The given numbers in this problem are both negative so remember that whichever number is furthest to the right is the larger value. Watch this short video and see how to...

There are times when you might want to use a number line to help you visually understand what is happening mathematically. Subtracting integers might be one of those times. So take a look and see which direction you need to move on the...

A very simple explanation of adding two negative numbers together. Well, it's a mathematical explanation that includes moving the negative and using absolute value. Just watch the instructor as she shows you the steps and it will make...

Given a trinomial to factor, figure out the signs that will be in the resulting binomials. There are three cases for the combination of signs. Check out this video, it will prove to be very helpful to know how to determine the signs...

If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

After multiplying integers that have positive and/or negative signs, how is the sign of the product determined? This is a foundation skill that your pupils should know like the backs of their hands. If you need to reinforce the rules of...

It's not really a shortcut but an equivalent equation. That's how these two perfect square equations work. So when you see an expression written out and it fits the perfect square of a trinomial criteria it can be rewritten in the...

As a follow up to his video on adding integers with the same sign, Duane created this shortcut video to make life easier. He tells learners they can ditch the number line and just add the absolute value of each number and attach the sign.

Duane uses a vertical number line to show learners how to add integers with the same sign. The vertical number line is an effective visual tool that will help viewers better understand exactly what happens when two positive or two...
