Curated OER
The Elimination Method
Tenth graders investigate the Elimination Method in the solving of equations. They solve the equation using this method in examples with the teacher and then transfer the new knowledge to independent practice.
Curated OER
Linear Inequalities
Ninth graders practice recognizing similarities and differences found in the graphing of inequalities and equations. Once observatioons are made they solve some of their own applying prior knowledge.
