Adding Fractions with Different Denominators

To add and subtract fractions with different denominators students are taught to use equivalent fractions to find a common denominator.  As learning progresses numerical methods are used to find the lowest common multiple of the two fractions.  Completing fraction pyramids give the class an opportunity to consolidate and apply their learning.
Differentiated Learning Objectives
  • All students should be able to add and subtract fractions where one denominator is a factor or multiple of another using a fraction wall.
  • Most students should be able to add and subtract fractions where one denominator is a factor or multiple of another using equivalences.
  • Some students should be able to add and subtract fractions where neither number is a factor or multiple of the other.

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 […]
