Part 1: Solving Equations
Learning Objectives
Grade D
To be able to demonstrate a method for
solving linear equations
with unknowns on both sides and/or
brackets.
Can you explain how to simplify these equations
so they only have
one unknown?
To be able to demonstrate a method for
solving linear equations where the variable occurs in the numerator of a
fraction.
What is the reverse operation of division?
Grade C
To be able to demonstrate how to change the
subject of an
equation.
Why might we want to change the subject of
an equation? Can you
give a real life example?

Part 2: Plotting Quadratics
Title: Solving Quadratics using Graphs
Room: 22
Learning Objectives
Grade C
To be able to solve quadratic equations from their graphs.
How many solutions do you expect there to be?
Resources
In groups plot the graphs of one (or two) of the equations on the slide.
Create a group poster (example on slide) with graph.
Look at further examples of factorizing to solve quadratics.
