Problems with Simultaneous Equations
PowerPoint, Notebook, Flipchart Presentations that include a starter, two main activities and a plenary.
Differentiated worksheet with solutions
Interactive question and answer generator
To introduce the idea of equivalent equations the starter involves calculating the common factor between multiple equations in order to determine the odd one out. In the main phase the teacher is provided with progressively more complicated pairs of equations in which to model the idea of making coefficients equal in order for an unknown to be eliminated.
Differentiated Learning Objectives
All students should be able to solve a pair of simultaneous equations with different coefficients using the elimination method
Most students should be able to derive and solve a pair of simultaneous equations by equating two unknowns.
Some students should be able to equate two unknowns from a diagram and solve using the method of elimination.
