Finding the Highest Common Factor

Students learn about finding the highest common factor of numbers and terms.  More able student learn how to find the highest common factor of expressions.At the start of the lesson students recap finding factors of numbers and simple terms.  In the main phase they find the factors of numbers and terms to select the highest factor that is common to all values.  At the end of the lesson they are challenged to solve a real life problem by finding the highest common factor of two numbers.
Differentiated Learning Objectives
  • All students should be able to calculate the highest common factor of two integers when given their factors.
  • Most students should be able to calculate the highest common factor of two or more integers.
  • Some students should be able to calculate the highest common factor of two or more terms.

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 […]
