In this quadratic inequalities instructional activity, students graph six quadratic inequalities. They solve two quadratic inequalities to identify one solution. In this quadratic inequalities instructional activity, students draw the parabola and shade inside or outside of the shape to indicate the range of answers.
Students investigate inequalities. In this algebra lesson, students explore what a solution to an inequality is and understand the relationship between an expression and its graph. The lesson requires the use of technology in the form of the TI-Nspire handheld and software.
In this quadratic inequalities instructional activity, 9th graders solve and graph 10 different problems that include various forms of inequalities. First, they solve each equation shown algebraically. Then, students state the solution set of the given problems and graph them on a number line. They also graph each given inequality.
A teacher's guide precedes the five-page instructional activity on solving absolute value problems. A summary, essential question, launch and exploration activities are suggested to go along with the assignment. You might want to know that the instructional activity itself, while pertinent to the skills of solving and graphing absolute value problems on a number line, is dry; there are no real-life applications.
Students investigate braking distance for various speeds. In this braking distance for various speeds lesson, students plot data for braking distances under three conditions, normal, using a phone, and wet weather. Students find a quadratic regression line to model the data. Students write quadratic inequalities that represent the speed intervals at which a pedestrian would be seriously injured.
Young scholars explore the concept of algebra topics. In this algebra topics lesson, students solve linear and quadratic equations. Young scholars solve systems and factor equations. Students practice problems involving perfect square trinomials and differences of squares.
In this mid-term worksheet, students solve equations dealing with such topics as slope-intercept, quadratic equations, symmetry, writing algebraic equations, matrix, functions, combinations, and inequalities. This 51-page worksheet contains 80 multiple-choice problems. Answers are provided at the end of the problems.
Eighth graders extend skills for representing and solving linear equations to linear inequalities. Lesson activities build understanding and skill by plotting ordered pairs of numbers that either satisfy or do not satisfy a given problem situation involving a linear inequality.
Students graph quadratic functions and solve quadratic equations. For this quadratic math lesson, students view a PowerPoint about the Civil War and brainstorm about parabolas. Students use a graphing calculator to practice graphing examples from the PowerPoint. Students discuss and complete the parabola form handout.
