Conjectures and Conclusions
Students draw conclusions and make conjectures given a specific scenario. In this geometry lesson plan, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is what it is.
Curated OER
Investing
Students collect data on investments and draw conclusions. In this algebra lesson, students analyze exponential graphs as they relate to money. They discuss the cause of an account balance being high or low.
Curated OER
The Absolute Truth
Learners solve problems of inequalities and equations. In this algebra lesson, students add, subtract, multiply and divide to solve inequalities. They graph their solutions on a number line.
