Testing solutions of equations and inequalities

The  exercise appears under the 6th Grade Math Mission. This exercise practices checking answers by substituting values into equations and inequalities.

Types of Problems
There are two types of problems in this exercise:


 * 1) Test the solution to the equation: This problem provides an equation and some possible solutions. The student is expected to select the numbers that solve the equation from a multiple select list.Tsoeai1.png
 * 2) Test the solution to the inequality: This problem provides an inequality and some possible solutions. The student is expected to select the numbers that solve the inequality from a multiple select list.Tsoeai2.png

Strategies
An ability to compute mentally and substitute values into an equation or inequality can assist with efficiency on this exercise
 * 1) The numbers are not large so it substituting the values in can be done mentally in most cases.
 * 2) There will only be one selection for equation problems.
 * 3) There are few examples and they repeat quickly.

Real-life Applications

 * 1) This skill can be used on standardized multiple choice tests, such as the SAT.
 * 2) This skill is used to check answers to equations in any context where an equation or inequality has been performed.
 * 3) This skill will lead into shading inequalities in later algebra.
