Objectives
Increase conceptual understanding of solutions to simultaneous equations, specifically those with three variables and including the intermediate steps as variables are successively eliminated.
Vocabulary
- Simultaneous Equations
- Substitution
- Elimination
- Linear
- Plane (Flat surface) /
About the Lesson
Five sets of three equations, each consisting of three variables. Students used the scaffolded learning document to visualise and successively eliminate variables to find where the three planes intersect. Visual information helps increase understanding and also to check answers.
