Slippery Slope
Students define patterns, relation and function. In this algebra instructional activity, students find the slope of a line and write equations of line. They model the slope using real life scenarios.
Curated OER
Between The Extremes
Students analyze graphs for specific properties. For this algebra lesson, students solve equations and graph using the TI calculator. They find the different changes that occur in each graph,including maximum and minimum.
Curated OER
Know the System
Students identify the different systems of equations. In this algebra activity, students solve systems of equations using graphing, elimination and substitution. They use the Ti to graph their systems.

Add & Subtract Fractions w/Unlike Denominators, 2
Students use several examples to create a method for adding and subtracting fractions with unlike denominators. They present these methods to the class and then practice applying methods to sample problems.
Curated OER
Discovering Pi
Students investigate the math concept of Pi (specifically, what pi is, the significance and how it is used in the real world). This is a hands on activity in which the students actively participate with their investigations.
The...
