Teaching Outlines
Concept #1 - Where do I use simultaenous equations
Learning objectives
- There are two quantities/ parameters that are used together to describe something.
- This is of the forms ax+by = c
- You need two sets of equations to find the solutions.
- Extend this understanding for different sets of variables.

Concept #2 - Graphical Method of Simultaneous Equations
Learning objectives
- State a given problem in algebraic terms
- Identifying the variables
- Interpret a linear equation as a line
- Understand that the solution is a point on both the lines, they intersect
Notes for teachers
It is better to use the graphical method before the algebraic manipulation.
