Quadratic Inequalities

In this mathematics lesson students learn how to solve quadratic inequalities by identifying the roots to sketch the graphs.  As learning progresses they are challenged to identify regions on a grid the correct algebraic notation.  The start of the lesson is used ot recap solving simple quadratics using factorisation and the balance method.
Differentiated Learning Objectives
  • All students should be able to solve a quadratic inequality using the balance method.
  • Most students should be able to solve a quadratic inequality in the form by factorising.
  • Some students should be able to solve a quadratic inequality with non-integer roots using the formula.

Teaching Mathematics for a Growth Mindset

Inspiring students to enjoy maths and feel the success that comes with attempting a difficult challenge is why I teach.  The feeling of success is addictive.  The more students experience it the more they want it and the further out of their comfort zone they are willing to go to get more of it.  Teaching […]

Equation of Straight Line Graphs

To find the equation of straight line graphs students need to calculate the gradient using two pairs of coordinates and the intercept which is the y value of where it crosses the vertical axis.  Examiner’s reports of past exam questions show students are more able to find the intercept of a straight line than they […]
