Ninth graders investigate linear inequalities.  In this Algebra I lesson, 9th graders explore the mathematical application of “at least” and “at most” by writing an inequality using two variables, graphing the inequality, and interpreting the result.   
Students solve inequalities. In this inequalities lesson, students evaluate simple inequalities. They examine vocabulary words. Students participate in breath holding activities and write inequalities to represent the activity. In teams, students play tic-tac-toe and name that number to identify inequality equations. They write journal entries and create flow charts to identify the steps in solving inequalities.
Young scholars explore number sense by completing world problem worksheets. In this inequality solving lesson, students identify what a compound inequality is and practice transcribing word problems into number equations. Young scholars complete an inequalities test and are assessed on their performance.
Third graders read problems, then solve them using counters, number lines, or other manipulatives.They discuss various ways that the problems can be written mathematically. When students are solid with completing equalities, they are presented with inequalities and solve those in a similar manner.
Graph systems of linear inequalities and use tracing paper to graph linear inequalities. Learners place the traced graphs on top of each other to determine the solution to the system.
Students graph the system of a linear inequality defined by a polygon. In this inequalities lesson, students create a polygon that models the solution of the given problem. Students write two inequalities of x and y that produce non-negative numbers. Students also sketch their prediction of the graph of the grid provided.
Students solve linear inequalities. In this solving linear inequalities lesson plan, students solve one step inequalities algebraically. Students graph the solutions on a number line. Students compare the graphs of various inequalities such as -x > 4 and x> -4.
Ninth graders investigate linear inequalities.  Students explore the relationship between the table of values and the graph of simple linear inequalities.  Students solve one-step linear inequalities and compare their paper and pencil results to the graph of the handheld. 
In this algebra worksheet, students solve systems of inequality using the graphing method. There are 5 questions with lots of examples and an answer key.
In this linear inequalities worksheet, students solve and graph systems of inequalities on a coordinate plane. Examples and explanations are provided. This five-page worksheet contains 32 problems. Answers are provided at the end of the document.
Students prove and apply theorems of triangle inequality and hinge theorem. In this geometry lesson, students will discuss which triangle is bigger and why. They will use theorems, such as Exterior Angle Inequality or the Pythagorean Theorem to prove their statements.
Seventh graders look at patterns to discover how to graph an inequality.  In this graphing inequalities lesson, 7th graders observe and investigate the puzzle of solving inequalities through graphing.  Students work in groups to solve inequality problems on a worksheet. Students graph their results.
In this algebra worksheet, students solve inequalities by identifying and solving for the missing variable. They graph their solutions on a number line. There are 10 questions with an answer key.
Students explore how to graph a linear inequality. They determine if a point is in the solution set. Students solve linear inquality application problems. They graph linear equations, and solve linear equations for a given variable.
Put geometry skills to the test! Learners solve compound inequalities and then graph the inequalities on a coordinate plane using their geometric skills. They identify the slope and y-intercept in order to graph correctly. I like this lesson because it uses multiple colors to differentiate concepts as they are represented on the graph.
Solve equations and graph systems of inequalities. Designed as a lesson to reinforce these concepts, learners revisit shading and boundaries along with solving linear inequalities.
Students compose equations and inequalities whose solutions are the integers 1-31 and utilize them to number one month of a calendar. They take notes on two ways to work backwards from a solution: by using the number and by setting x equal to the number.
For this algebra worksheet, learners solve systems of inequalities by graphing and shading the shared solution. There are 14 questions with an answer key.
Challenge your students' algebra skills with this activity, which presents students with several types of problem sets, including solving inequalities, graphing, word problems, and a set of algebra problems that may or may not require correction by the students. This activity could function well as a long-term homework assignment or midterm.
In this mixed equation and inequality worksheet, students solve various types of equations requiring the use of absolute value, system of equations, polynomials, and square roots. This three-page worksheet contains 60 algebra problems. Answers are provided at the bottom of page three.
