A difference is described between two values. Represents the solution set as a conjunction rather than a disjunction. Uses the wrong inequality symbol to represent part of the solution set.
The distance from a number, x, to the number 10 is seven units on the number line. Examples of Student Work at this Level The student: A machine is used to fill each of several bags with 16 ounces of sugar.
What is the difference? Provide additional examples of absolute value inequalities and ask the student to solve them. This is 45 out of 51 in the solving equation series.
Model using simple absolute value inequalities to represent constraints or limits on quantities such as the one described in the second problem.
Knowing this will help you in future math courses. What are these two values? What are these two values? Does not represent the solution set as a disjunction. Enter solutions from smallest to largest. That is written as x - 10 or 10 - xyour choice.
Do you know whether or not the temperature on the first day of the month is greater or less than 74 degrees?
How did you solve the first absolute value inequality you wrote?
If the bag weighs. The student does not understand how to write and solve absolute value inequalities. What would the graph of this set of numbers look like?
After the bags are filled, another machine weighs them. Provide additional opportunities for the student to write and solve absolute value equations.
Instructional Implications Model using absolute value to represent differences between two numbers. As usual, they throw problems at me while only giving the barest of model problems.
Can you explain what the solution set contains? How can you represent the absolute value of an unknown number? Should you use absolute value symbols to show the solutions? Can you reread the first sentence of the second problem?Solving Word Problems Using Absolute Value — Writing Absolute Value Inequalities Given a Word Problem.

Absolute value equations (part one): How to solve an equation containing an absolute value sign (part one).
This is 45 out of 51 in the solving equation series. This is 45 out of 51 in the solving equation series. Students are asked to write absolute value inequalities to represent the relationship among values described in word problems.
the student is unable to correctly write an absolute value inequality to represent the described constraint.Download
