Adding and Subtracting Algebraic Fractions

The key idea with adding and subtracting algebraic fractions is to create common denominators.  As learning progresses students use algebraic techniques such as simplifying products and expanding brackets to evaluate the fractions.
Differentiated Learning Objectives
  • All students should be able to add and subtract a pair of algebraic fractions with numerical denominators.
  • Most students should be able to add and subtract a pair of algebraic fractions with a single unknown as the denominator.
  • Some students should be able to add and subtract a pair of algebraic fractions with an algebraic expressions as the denominator.

How to Simplify Surds

When learning how to simplify surds students need to understand the difference between a rational and irrational number. Rational numbers include integers and terminating and repeating decimals. They can be written as a fraction with both the numerator and denominator as integers. An irrational number is a number which, in its decimal form does not […]

Sharing an Amount to a Given Ratio

There are three common methods for sharing an amount to a given ratio.  Depending on the age group and ability range I am teaching I would choose one approach over the other two. The three methods are: Using fractions Unitary method Using a table In this blog I will demonstrate each of the three methods […]

Plotting Scatter Graphs and Understanding Correlation

To introduce plotting scatter graphs and understanding correlation I ask students to think about the relationships between different variables and to describe how they might be related. Here’s my starter activity which students discuss in pairs then present to me on mini-whiteboards. When the students have had time to discuss the matching pairs we talk […]
