Integer Solutions to Inequality
When is the last time you assigned your students only one problem? This seemly simple problem requires learners think like a mathematician and reason about how to solve this compound inequality in one variable. More than just using...

Graphing Calculator Investigation Graphs of Relations
Learners investigate relations in this algebra lesson. They graph the set of ordered pairs that determine a relation. Using a TI-83 Plus, your learners will enter the coordinates in a list, create a scatter plot, and manipulate the...
