Like most people, I begin my great on absolute value with a story around distance.I love informing stories in class. Stories space a method to lessen stress in course and carry out a method to have some fun. In mine story, I drew a number line. I placed the institution at zero and also told the student that i live 10 block from the school. I then asked where if they could determine whereby I live.

Of, food the an initial answer to be at confident 10. Many students to be happy v that answer. When I pressed for one more answer, they captured on fast (they know me well).

Absolute value Stories

This is necessary for students come understand. Absolute value represents the distance. Street is always positive. The other story ns tell is around my car. Mine odometer reads 10,000. I take trip 100 miles to mountain Diego (I live in the Inland realm in southerly California). What does my odometer read once I get to san Diego?

Of course, it currently reads 10,100 miles. So once I come home, i am going the various other way. Carry out I currently subtract 100 miles? (Students answered only if ns am driving backward, lol). Students need concrete models. Telling stories about travel and also location the are acquainted will help.

Different teaching Methods

In a recent meeting, the subject of to teach absolute value equations was raised. That was exciting to hear the techniques that teachers preferred. Part were convinced that their an approach was the only one.

This is the means I generally teach this. I explain that the worth inside the absolute worth bars have the right to either be optimistic or negative, therefore we are going to have actually 2 answers. And also I collection up both equations as shown.

How I usually teach absolute value after the first initial lesson.

Connecting Models come Concepts

Another teacher took exception to this. She said it provides no sense to students. Her students require to recognize why the works. My method does not have an explanation. For she students the why is valuable. She demonstrated the she teaches it this way:

*

I know what you are thinking. This is a distinction without a difference. But to her eyes, the second technique makes sense to her. Since the expression within the absolute value bars can be confident or negative, then the noticeable procedure is to write the expression as confident or negative. This, she insists, can be described to students.

Using the Number Line

Another teacher walk not favor either. He is visual. Teachers that love Geometry like pictures and diagrams. The teaches the absolute worth is stood for on the number line together the distance from zero. Which functions fine as soon as there is no number through x in between the bars.

*

when others started asking questions, it gained a tiny confusing. I acquired confused. One more teacher to the rescue. He shared the following:

This helps students watch the equation. It gives some scaffolding because that students that need models. This was the way he learned the concept and also how the teaches it come students.

Providing Practice

I had never seen this version yet I tried it, questioning students to describe the price in words and also also carry out a solution. Students discovered it easier.

This worksheet formed a great introduction for students. This is the first introduction to absolute worth in class and an ext practice is needed.

Yet it was amazing to view teachers therefore enthusiastic around their strategies. Together students space different, that is necessary to administer a variety of methods to learn.
