Solving linear equations using the balancing method

A complete lesson on solving one step equations using the balancing method. Designed to come after pupils have solved using a flowchart/inverse operations, and as such the introductory slides put the two methods side by side, so pupils can relate them. I’ve also uploaded a lesson on balancing (but not solving) equations that would be a good precursor to this lesson.

Activities included:

Starter:
A set of questions to check that pupils can solve one step equations using a flowchart/inverse operations.

Main:

• Two slides showing equations represented on scales, to help pupils visualise the equations as a balancing problem.
• Four examples of solving equations, firstly using a flowchart/inverse operations and then by balancing. Then a set of similar questions for pupils to try, before giving any feedback.
• A second set of questions basically with harder numbers. Not exactly thrilling but necessary practice.
• A more interesting, challenging extension task in the style of the Open Middle website.

Plenary:
A prompt of an equation that is best solved using the balancing method, rather than inverse operations (hence offering some incentive for the former method).

Printable worksheets and answers included.
