# Writing and solving inequalities games

### Systems of equations and inequalities game

The first student or team of students to guess the correct value for the variable wins and gets to choose the next value and run the next round. Have them take and release two deep breaths, then say "Go" and begin counting seconds. Why is the inequality symbol reversed when the inverse operation involves multiplying or dividing by a negative number? Use this to help students determine how to budget the amount of money someone can spend each week over the course of five weeks and still have money left over. Questions must be in the form of an inequality such as, AIs x less than 0? Another example for an inequality is the minimum height sign at an amusement park. If not, the opposing team gets to ask the number of additional questions to reach their bid, then, guesses the number. The team continues to ask all the questions for their bid. Have them write a new inequality for each guess. Have each team bid for the number of questions they will need to ask you in order to guess the number ex. Those on the right by a negative number 2x. Have the students shade the left side of the graph if the y is less than the value of x and the right side if y is greater than x.

They stop by a partner and share their inequality. In algebra, inequalities are equations in which the answer can be a range of values instead of only one correct solution.

## Inequality games printable

Use one of their inequalities and solve it. Next curser to the inequality symbol, push b, type the number, curser to "done", b b. This will teach the students to think visually about inequalities and also chart out solutions for their equations. Show them the overhead picture of a speed limit sign attached. Teaching the Symbols To start teaching inequalities, start by familiarizing students with the symbols and vocabulary of inequalities. Integers, rational numbers and several operations may be used may be used in the expressions to set up several inequalities using operations on their initial compared to the time of the winner or any other time. Have every student write an example so there are plenty of examples for students to reference when they see equations appear on tests and homework. Have each team bid for the number of questions they will need to ask you in order to guess the number ex.

Next, have them ask a person sitting by them how long that person held their breath and write an inequality using their initial as the variable to represent their time and comparing to the number of seconds for the other person.

Watch the clock and count the seconds as they hold their breath as long as they comfortably can.

Have students look at the vocabulary and tell a partner something they know about one of the vocabulary words. Teaching the Symbols To start teaching inequalities, start by familiarizing students with the symbols and vocabulary of inequalities. Running a round will help students learn to think quickly about the relationships between numbers in terms of inequalities while guessing will help the students become familiar with the terminology.

Those on the right by a negative number 2x.

Show them the overhead picture of a speed limit sign attached. Have them write words and symbols for the home prices sign attached. The first student or team of students to guess the correct value for the variable wins and gets to choose the next value and run the next round.

## Equation games

To enter a student's question, type -1 and cursor down to x. Use this to help students determine how to budget the amount of money someone can spend each week over the course of five weeks and still have money left over. Tell them you will solve an inequality to find a reasonable time for someone. Have them take and release two deep breaths, then say "Go" and begin counting seconds. Have them write a new inequality for each guess. The number is between and 25 or choose any range appropriate for the class. Have each student write the words and the inequality for a real-world situation. For example, 3 plus x is less than 5 is an inequality in which any number under one can be a solution. The first student or team of students to guess the correct value for the variable wins and gets to choose the next value and run the next round. Have the students match the symbols with the wording then define each one by writing an example equation on the board. Have students look at the vocabulary and tell a partner something they know about one of the vocabulary words. If not, the opposing team gets to ask the number of additional questions to reach their bid, then, guesses the number.

Have every student write an example so there are plenty of examples for students to reference when they see equations appear on tests and homework. Type the question into the calculator and press enter to check for yes 1 or no 0.
