Graphing Absolute Values Teacher Resources

No matter how it is written, it still is a line. A video shows class members how to take points and write the equation of the line that goes through those points. It then outlines how to develop the equation whether the points are...

Provide the definitions of parallel and perpendicular lines, as well as the relationships between their slopes. Two examples explain the process of finding the equation of either a perpendicular or parallel line to another line through a...

Introduce the basics of evaluating a function using function notation with a video that makes connections between evaluating a function and substituting into an expression. The short presentation works through three examples of...

The representation of a relationship really depends. The difference between dependent and independent variables is the focus of a short video that also includes examples of determining the types of variables. The presenter makes the...

Function, function, what is your notation. Introduce your class to function notation with a video that shows examples of how to evaluate functions at numerical values along with algebraic values. The last example shows pupils how they...

I'll do algebra, but graphing is where I draw the line! Video explains how to find the slope of a line when starting with word problems. It includes positive and negative slopes as well as how to identify intercepts.

Introduce learners to independent and dependent variables with an informative video.The two variables are defined via inputs and outputs. It makes clear that the independent variable is the one that the person has control over, while the...

Rates of change can be a slippery slope. The resource makes the connection between the rate of change and the slope of a line. It continues on to provide examples of how to interpret the slope and the y-intercepts of linear equations...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

Got that factoring thing down? Time to apply it! A helpful video explains the process of simplifying a rational expression, showing pupils how to factor a majority of expressions using special patterns. Here is a great way to begin the...

Clarify complex math concepts with a helpful video. Learners view ways to work with ratios and proportions while discussing vocabulary and notation. After solving proportions, they apply the new strategy to word problems.

A geometry video explains how to solve for midpoint, length of a line, and use the Pythagorean Theorem. It includes multiple guided practice problems for all three equations.

A mathematics video explains the parts of an equation and reviewing relevant vocabulary. Next, it covers one-, two-, and multi-step equations. It includes a few example problems for each type as well.

Mathematics is not a spectator sport. A video explains how to identify literal equations and why pupils will need to use them. It goes on to describe how to solve for a specified variable.

Why did the variable add its opposite? To get to the other side. A video introduces the concept of variables. It compares and contrasts independent and dependent variables in a variety of problems.

Introduce the concept of domain and range with a video that starts with the formal definitions of the domain and range and moves on to the practical descriptions used to determine them. The presentation explains how to find the domain...

What's my line, anyway? A video covers the aspects of finding an equation of the best-fit line for a set of data. It works through plotting the points to drawing a line that appears to represent the data. The presenter suggests finding...

Correlate the responses to identify the cause. A resource presents how individuals sometimes confuse the issue between correlation and causation. The video provides examples of different variables that are correlated — but one does not...

Is it better to be average or an outlier? It all depends on your perspective! The video explains the impact an outlier has on central tendency. Using multiple examples to solve for mean, median, and mode, the video proves that having an...

Start this activity with a brief description of how to solve absolute value inequalities. A space is provided to help classify the inequalities into types (greater than, less than, or equal to) and for learners to show how to graph their...

We all know linear equations are special, but the direct variation equation is extra special! The video begins with a set of data to illustrate a direct variation relationship. It then completes examples of writing direct variation...

Use this video to show your learners an example of how to translate word phrases into an equation to solve a real-world problem. The presenter begins with a review of how to use cross products to solve a proportion, including how to do...

Finding the length of the hypotenuse of a right triangle can be done in two ways as shown in this video. First, the hypotenuse is found using the Pythagorean Theorem. Next, the distance formula is used to solve the same problem. 

Demonstrate how to use a box and whisker plot to place a line of best fit accurately with an educational video. It begins with a review of box and whisker and line of best fit, and then uses an application problem to describe the process.
