Solving by Graphing Teacher Resources

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...

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.

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...

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...

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...

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...

Set builder notation? What's that? Don't know? Need a refresher? Kind of remember? Well, watch this video and learn all about writing set builder notation. The instructor explains braces, variables, and inequalities to be able to write a...

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...

Use this instructional activity as a warm up, a refresher exercise, or a practice after a more detailed lesson on graphing linear inequalities in two variables. Start with boundaries that are horizontal or vertical, then move into graphs...

In this solving quadratic equations worksheet, students select the best method to solve a quadratic equation and then solve five quadratics.  Fully worked examples  are provided.

Intersection. Isn't that where paths cross? And so it is in math also. Observe the teacher as she draws a number line and plots two inequalities on it. She then explains how to get the intersection of these two lines. Then she draws...

What is a compound inequality? Most inequalities have two parts, one on each side of the inequality symbol. In this compound inequality there are two inequality symbols and three terms. Watch this video and learn how to solve this...

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...

Middle schoolers gather leaves and trace them on graph paper. They plot coordinates that approximate the shape of the leaves and share those coordinates as "worksheets" for other students to complete.

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...

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. 

What makes an expression an inequality? Well, it would be considered an inequality if the expression has a greater than symbol, a less than symbol, a greater than or equal to symbol, or a less than or equal to symbol. This would mean...

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...

Learners investigate the properties behind the quadratic equation. In this algebra lesson, students identify quadratic equation in the real world. They graph the parabola and identify the vertex and intercepts.

In this algebra worksheet, students are guided to choose the best method to solve problems using graphing, factoring, completing the square, and quadratic formula. There are 4 problems with an answer key.

Students practice graphing compound inequalities. They draw a Venn Diagram on two different sports visualizing that their is a middle section on commonality among the two sports groups and then relate that concept to compound inequalities.

In this algebra worksheet, students solve problems by graphing inequalities, finding the slope of a line and identifying functions. This is a review of chapter 2 on an algebra test. There are 21 questions.
