What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

Demonstrate the meaning of an absolute inequality using three different methods. Here, scholars explore absolute value inequalities through graphing, number line distance, and compound inequalities. Pupils complete various activities to...

Teach solving absolute value inequalities through inquiry. Groups use their knowledge of absolute value and solving inequalities to find a solution set to an absolute value inequality. Working collaboratively encourages discussion,...

Learners evaluate absolute value expressions. In this algebra lesson, students apply the order of operation as they solve expressions with absolute value bars. They analyze the two different answers resulting from an absolute value...

Don't let a little challenge get between your pupils and their learning! Scholars compare two absolute value functions to recognize patterns and use them to build their own functions with outputs that are between the given. They then...

Students solve equations with absolute value bars. In this precalculus lesson, students graph and identify the vertex and translation of absolute value functions. They match equations with given graphs.

Young scholars solve equations using absolute values and roots. In this algebra lesson, students solve equations and write their solution on a number line. They solve for x as it relates to distance or absolute values. They order roots...

Learners solve absolute value problems, In this algebra lesson, students discuss distance as they relate it to absolute values. They distinguish between negative and positive numbers inside of an absolute value bars and how the answer...

Students solve equations with absolute values. In this algebra lesson, students rewrite equations with absolute values to find the 2 values for x. They graph their solutions after solving for x.

Using the real-world example of elevation, above or below sea level, young mathematicians interpret expressions using negative signs, and absolute value. This task provides a good opportunity to discuss the notion of magnitude and...

If you know one, you know them all! Parent functions all handle translations the same. This lesson examines the quadratic, absolute value, and square root functions. Pupils discover the similarities in the behavior of the graphs when...

Why is that graph wider? Pupils learn about stretching and shrinking graphs of square root, absolute value, cubic, and quadratic functions. They study both vertical and horizontal stretches and shrinks in addition to reflections. 

Students explore the concept of transformations.  For this transformation lesson, students use an applet that is an interactive absolute value graph applet.  Students manipulate the applet to examine the change in the function...

Students investigate absolute value functions.  In this Algebra II/Pre-calculus/Calculus lesson, students explore the formal definition of absolute value and apply the piece-wise definition to solve inequality problems. ...

Which is colder -12 or -18? Temperature is natural real-world application of ordering rational numbers. It's also fun to talk about the lowest recorded temperature on Earth. Take the time to discuss this inquiry with your class. 

Here is a lesson that starts with having geometers translate points using compass directions into an accurate picture of the problem. Then they must use their knowledge of the Pythagorean theorem or similar triangles to solve. This makes...

Students investigate linear, quadratic, and absolute value functions.  In this Algebra II lesson, students observe and describe family traits that exist among functions as they use technology to graph several functions on the same...

Solve a real-life problem using function-building skills. Presented with an open-ended question, scholars complete a checklist to create and justify a solution in an interesting algebra project. The checklist asks for justifications of...

Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

Students solve problems using the opposite, reciprocal and powers. In this algebra lesson, students solve problems with inequalities and absolute values. They show understanding of the basic content of math in this lesson.

Play a game of capture the points. Young scholars receive a number line with specific points graphed and must write an inequality that captures all the points. The second task of the algebra project is to write an inequality with...

A piece of this and a piece of that, add domain restrictions and create a piecewise function. Young scholars explore piecewise functions with and without context. Functions include both linear and quadratic parts. The module is the...

Functions behaving badly: the squaring function and the absolute value function are both zero at x=0. Yet when you divide each by x, different things happen. Here, your class will explore each scenario as a means to adding depth to their...

Young scholars investigate functions and their transformations. They move absolute value functions around on the coordinate plane, and then define the transformation and plot the new graph. The table feature of the TI-calculator is used...
