Forming and solving inequalities

In this lesson, we will discuss what different inequalities mean, and we will see an example of where we might see inequalities used in context.

Representing inequalities

In this lesson, we will substitute different values into an algebraic inequality to see if it is true or false.

Inequalities and substitution (Part 1)

In this lesson, we will continue our work on substituting into inequalities, this time considering negative numbers in more detail.

Inequalities and substitution (Part 2)

In this lesson, we will use the balancing method to solve inequalities. We balance the inequality by completing inverse operations to simplify the expressions.

Solving inequalities

In this lesson, we will set up and solve inequalities in the context of area and perimeter of rectangles.

Forming and solving inequalities (Part 1)

In this lesson, we will set up and solve inequalities in the context of word problems.

Forming and solving inequalities (Part 2)

In this lesson, we will investigate the relationship between different inequalities using bar models and "always, sometimes, never" statements.

Manipulating inequalities

In this lesson, we will continue to investigate the relationships between inequalities and equations. We determine truth statements based upon a given inequality.
