Level: Year 10, Year 11 and Year 12
Author: Michael O’Connor
Description:
Simultaneous Equations are so called because they describe what happens to the same variables under different conditions. Solving simultaneous equations is about finding the point, or points where both equations give the same results. There are several methods for finding these solutions. At year 10 we will explore the Graphical, Substitution and Elimination Methods. In year 11 we will add the Matrix Method as well.
The unit includes an AMSI Interactive online module, a range of other AMSI Schools and external links and video tutorials and some extension or enrichment ideas to take their understanding further. A short quiz at the end of the AMSI Interactive will help students to test their understanding at the completion of the unit.
If you do not already have a copy of Geogebra on your device, download it here. For PC’s and Macs the Classic 5 is recommended. This software is free and by downloading the prepared files you do not need to worry about internet speeds.
