Testing solutions of equations and inequalities word problems

The topic  is a topic under the 6th Grade Math Mission. This exercise practices the skills of substituting values into expressions and verifying solutions of equations and inequalities.

Types of Problems
There is one type of problem in this exercise:


 * 1) Find which solutions satisfy: This problem describes a word problem that can be modeled with an equation or an inequality, and also provides the equation or inequality. The student is asked to verify which of the solutions in a multiple select list are valid for the situation.Seaits1.png

Strategies
This exercise is easy to get accuracy badges because values can be placed in a calculator to see if they work. The speed badges are medium because it is necessary to sometimes go through all the solutions to find which ones work.
 * 1) Solving the equation or inequality can help determine the correct answers, but is not necessarily time efficient for speed badge purposes.
 * 2) On inequalities, once a solution is found it is possible to use the direction of the inequality to provide additional solutions.
