Understanding Inequalities and Absolute Values

The video tutorial covers writing and graphing inequalities, starting with an introduction to the concept. It includes activities such as estimating heights and matching stories with inequalities and number lines. The tutorial also involves estimating basketball hoop heights using inequalities. The session concludes with a summary and discussion of homework related to inequalities.

• A number line

• A table

• A picture
