Given a real-world context about the number of balls in a bag, we find a linear inequality that correctly depicts the situation. [2:19]
Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.
This tutorial for students new to algebra provides explanations, definitions, examples, and practice problems. The practice tests cover topics such as real numbers, fractions, equations, graphing, and exponents.
A tutorial on how to graph a linear inequality in two variables. The tutorial offers step-by-step instruction and examples of how to graph linear inequalities.
Students show what they know about equations and inequalities.
If a < b, what do we know about a and b? If b < c < d, how could we show that on a number line? Students continue creating inequalities and graphs to represent situations.
Students will practice how to solve equations and inequalities using tables and diagrams. Lesson includes worksheets and videos to help implement this lesson.
A lesson for students to work with writing and graphing inequalities. Documents to execute the lesson are included.
As in life, there is not always one solution to a problem.
Student activist Jonathan Butler and Congressman John Lewis sit down to discuss the Eyes on the Prize series and the Civil Rights Movement in this video from Eyes on the Prize: Then and Now. Lewis reflects on the 1965 Selma to Montgomery protest march. Shortly after the march began, Alabama State troopers met the marchers with violence as they crossed Selma's Edmund Pettus Bridge. Lewis also describes experiences from his childhood and youth, when he began to question segregation and other inequalities, and first's student activists. [4:28]

This task is the first in a series of three tasks that use inequalities in the same context at increasing complexity in 6th grade, 7th grade and in HS algebra. Students write and solve inequalities, and represent the solutions graphically.
Gapminder collects hundreds of statistics related to global economic, health, and social development and analyzes the relationships between them across different countries and time (a few indicators go back to 1800).
Gain an understanding of how to list the sides of a triangle in order from shortest to longest by viewing examples and a video lesson. [1:01]
