Learners use the inequality theorem to solve triangles and their properties. For this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a triangle and relate it to the inequality theorem.
Students examine poverty and inequality in America. In this current events lesson plan, students read the provided articles "Poverty," "Inequality Growing in America," "Inequality: Views on Causes, Effects, Remedies," and "Theories on the Origins of Poverty and How to Reduce It." Students respond to the provided discussion questions.
Third graders understand the mathematical signs for less than, greater than, and equal to. In this solving equations and inequalities lesson, 3rd graders compare numbers using symbols for equality or inequality. Students answer questions determining if the equation is equal or not equal.
In this inequalities worksheet, 10th graders solve and complete 23 various types of problems. First, they find the area of an inscribed square in a circle shown. Then, students find the total area of the inscribed polygon and deduce bounds for pi. They also use the results to find a formula for the polygon and write a conjecture.
It all comes together in this video, in which Sal uses the concepts from his previous videos (inequalities involving adding, subtracting, multiplying, and dividing) and addresses them in several problems dealing with compound inequalities. He successfully takes a high-level, often-confusing skill and makes it easy to understand with his straightforward approach.
Beginning a "handful of fairly simple inequality videos," Sal demonstrates a few inequality problems in which mathematicians need to add or subtract. Though he states that his goal is to familiarize viewers with the notation, his problem-solving skills are equally beneficial for even the most advanced pupils.
Things get a little more complicated in this video, which features Sal solving several inequality problems involving multiplying and dividing by positive and negative numbers. Additionally, he shows a few more kinds of notation to describe the solution set of an equality.
A number of problems involving inequalities and defining the variables are a piece of cake to Sal, and they will be to your Algebra pupils as well after they watch this video. Sal's careful explanation and clear annotations are key to understanding a concept that can complicate an already complex algebra problem.
Practice problems are great ways to engage your charges with a new concept. Sal solves for x + 8 less than or equal to 6 and then graphs the solution. First, he subtracts 8 from both sides, and then he subtracts 6. Next, he draws a number line to plot his answer. This is a very simple example and very clearly demonstrated; it would be appropriate for those who are new to inequalities.
If your class has a grasp on the concept of graphing systems of equations and has worked inequalities, then it's time to expose them to the wonders of graphing systems of inequalities. Using various colors and a graph, Sal explains what each inequality represents and why it is positioned as it is on the graph.
Students explore number sense by completing world problem worksheets. In this inequality solving instructional activity, students identify what a compound inequality is and practice transcribing word problems into number equations. Students complete an inequalities test and are assessed on their performance.
