# Interactive video lesson plan for: Introduction to inequalities

#### Activity overview:

I first explain the meanings of the four symbols: less than, greater than, less than or equal, and greater than or equal.

We then look at how simple word phrases can be "translated" or written as inequalities using a variable.

Next is time to PLOT some simple inequalities (such as x is greater than 6 or x is less than or equal than 10) on a number line, and when to use an open circle versus a closed circle.

We also solve simple linear inequalities in a given set.

Lastly, we look at how to use the number line to actually SOLVE some inequalities.
