High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

English and math have more in common than you think. Make a connection between a compound sentence and a compound inequality with an activity that teaches learners the difference between an "and" and "or" inequality through solutions...

Fifth graders explore equality and inequality by participating in a Tilt/Balance activity. The students listen to the story "Lemonade for Sale" by Stuart J. Murphy and use equations to graph lemonade sale profits.

Guide your class through the intricacies of solving compound inequalities with a resource that compares solutions of an equation, less than inequality, and greater than inequality. Once pupils understand the differences, the...

High schoolers explore the concept of linear inequalities. In this linear inequality lesson, students graph linear inequalities using Microsoft Excel.

Learners investigate the Napoleon triangle theory. In this polygon lesson, students  differentiate between the boundary points, interior and lattice point of a polygon. They apply concepts of equilateral triangles to solve...

Math masters are introduced to graphing inequalities on a number line. After reviewing inequality symbols, they practice representing them on a worksheet. This simple lesson plan serves its purpose.

Do properties of equations hold true for inequalities? Teach solving inequalities through the theme of properties. Your class discovers that the multiplication property of equality doesn't hold true for inequalities when multiplying by a...

Students graph and shade inequalities. In this algebra activity, students graph inequalities using the slope-intercept form. They shade the side of the line that is the solution and identify the domain and range.

Students investigate Income and gender preference. In this statistic lesson, students collect data of Income to see if one gender makes more than the other. Students examine the data and draw conclusions.    

Twelfth graders discuss discrimination on a global scale. They rank the problems they see as most pressing. In groups, they create a PowerPoint presentation showing Bangladesh's progress in dealing with discrimination.
