**41**-**60**of**2,965**resourcesStudents conduct research into the subject of age discrimination. They are exposed to different literature by the teacher in order to help start the research process. Students formulate intelligent opinions based upon the new information.

Students explore quadratic equations. Using dry erase boards, students graph solutions to quadratic equations and solve problems using the quadratic formula. They explore the quadratic formula and the use of the discriminant to predict the number of solutions. Links are provided to a quadratic calculator and animation of the derivation.

The ultra-glamorous Muppet, Miss Piggy, launches a study of discrimination and ways to develop a more inclusive community. A series of videos and activities raise awareness of discrimination and journal prompts asks participants to think deeply about the effects and consequences of their actions. Given the sensitivity of the topic, parental permission slips are recommended.

Eleventh graders explore the events of the Holocaust. In this cross curriculum lesson, 11th graders examine the differences between prejudice and discrimination. Students read various forms of literature and write journal entries.

Here is a worksheet that focuses on analyzing the discriminant of a quadratic equation to determine the nature of the roots of the equation. It consists of a three-column organizational chart to complete. The first column states a scenario for the value of the discriminant, such as less than zero or equal to zero. The task for the student is to complete the last two columns, which ask for the nature of the roots and the number of

*x*-intercepts of the graph for each given scenario. This resource can be used in a number of ways. It would be a good way to summarize concepts after an introductory lesson on the discriminant, it could be used for learners to record their observations during an introductory lesson, or it could be used as a review tool in the upper grades.The discriminant is such a handy little tool, and this worksheet provides good practice in using it. The worksheet contains ten quadratic functions. For each function, learners are asked to provide three sections of information. First, they compute the value of the discriminant, then use that value to determine how many roots the function has and whether the roots are real or imaginary. The last part of the task is to use the value of the discriminant and the nature of the roots to determine the number of

*x*-intercepts of the function's graph. This worksheet would be good to use for independent practice or group work during class, for homework, or for assessment.This worksheet provides excellent practice in analyzing the discriminant of a quadratic equation. It contains six quadratic functions. For each function, learners find the roots of the equation, compute the value of the discriminant, state the nature of the roots, sketch a graph of the function, and state the number of

*x*-intercepts of the graph. The worksheet is organized in table form, which helps pupils recognize how the value of the discriminant determines the nature of the roots of a quadratic equation and the number of*x*-intercepts of its graph. The worksheet can be used in a variety of ways, including independent practice to reinforce concepts, guided practice working in groups, or as a review activity. It would also be good to use as part of an introductory lesson on analyzing the discriminant.Consider complex numbers, roots, and quadratic equations. Use the discriminate as a way to determine the nature of a quadratic's roots. Then discuss the similarities and differences between quadratics with two, one, or no real roots. There are nine included worksheets, cha-ching!

Students investigate the pass laws that resulted in the Sharpeville Massacre. In this racism instructional activity, students find information about the massacre and attempt to find similarities to their own lives. They determine how similar incidents make a statement about race relations in the US. They investigate racial profiling.

Students work to understand learning disabilities and discrimination. For this teaching tolerance lesson, students examine what learning disabilities are and how people are discriminated against. There are different activities for students to complete based on grade level.
