Trial and Improvement

At the start of the lesson students set up an equation involving the area of rectangle which is solved using a method of trial and improvement.  The development phase goes on to consider quadratic and cubic equations using a table.  The plenary involves modelling the length needed to create a volume from an open box.
Differentiated Learning Objectives
  • All students should be able to solve a quadratic equation in the form x2+ab=c using trial and improvement.
  • Most students should be able to solve a quadratic and cubic equation using trial and improvement.
  • Some students should be able to solve any none linear equation using trial and improvements as well as derive the equation using known facts.

Comparing Datasets using the Mean and Range

In my experience, students, in general, find the concept of a mean straightforward to calculate and understand. However, the mean alone does not provide a complete picture of a set of data. To achieve this, a measure of spread is also required. The range is the simplest measure that can be used for this. Not […]

Solving Problems with Angles in Parallel Lines

Solving problems with angles in parallel lines is like solving a murder mystery.  One clue leads on to the next and the next until the murderer is found.  However, it doesn’t end there.  The detectives need to explain their reasoning in court using the relevant laws and procedures should the murderer plead not guilty.  If […]

Solving Two Step Equations using the Balance Method

An equation is when one expression, or term, is equal to another.  To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal.  There are two types of equations for secondary school mathematics, linear and none-linear.  In this blog I write about how I […]
