Solving an Equation with Function Machines

Students learn about solving an equation with function machines.  More able students can use the balance method to fing the unknown.At the start of the lesson students recap how to substitute numbers into expressions.  In the main part they are taught how to use the order of operations and function machines to find the unknown
Differentiated Learning Objectives
  • All students should be able to use function machines to find the unknown value in a single step equation.
  • Most students should be able to use function machines to break down an equation and find the value of the unknown.
  • Some students should be able to solve equations using the balance method.

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 […]

Plotting Quadratic Graphs on Cartesian Axes

In recent examiner reports it is noted how important it is for students to understand the properties of a parabola  when plotting quadratic graphs on Cartesian axes.  Students who have a secure understanding of parabolas can use them to correct miscalculated values in their table of results and are more likely to attain full marks […]
