If they students need more practice problems, Khan Academy will give them more of the same type of problems. There is a hint button for the students if they need it.

This will give you 8 problems to solve.

After watching the video, click on the green button above the video that says: Practice this concept.

This will bring you to the video lesson.

At the top, type in the search bar: absolute value equations.

Go to Scroll down and click on Algebra (2nd tab under Math).

Watch the video on absolute value equations on Khan Academy.

Instruct that what is done on one side of the equation (= sign), must be done on the other side of the = sign.

GOAL: to isolate the specified variable.

Instruct that minus and negative are equivalent.

Vocabulary: inverse operation, isolate, variable, constant, reciprocal, coefficient, absolute value bars, absolute value LESSON

Do you treat absolute value equations any differently than regular equations? I can construct an argument to justify my solution processġ.What is the difference in solving a regular equation and an equation with variables on both sides?Ģ.I can apply order of operations and inverse operations to solve equations.Construct a viable argument to justify a solution method.Ī.REI.3: Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.ģ Construct viable arguments and critique the reasoning of others.

Finally students will learn how to solve equations involving absolute value.Ī.REI.1: Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. \) and that the graph has been reflected vertically.Prior Knowledge: Students should have learned how to write equations, translate sentences into equations and equations into sentences, solve one-step equations using addition and subtraction, solve simple equations using multiplication or division, solve multi-step equations and solve equations with variables on both sides of the equation.
