What is the resource?

This PDF demonstrates 'substitution' – swapping numbers for letters in algebraic expressions. It offers clearly worked examples for secondary learners.

Why is substitution important?

Substitution opens up mathproblem-solving for all sorts of areas:

• Formulas: Think science formulas (speed, energy) – you often plug in values.
• Finding unknowns: When we have 'missing numbers' represented by letters.
• Real-life situations: Prices changes, measurements... substitution finds the final answer.

Why is this resource helpful?

The resource makes this skill less mysterious through:

• Step-by-step guides: Provides a breakdown of how to approach each problem.
• Varied examples: Covers basic expressions, those with powers, and negative numbers.
• Increases comfort: Lets students see worked solutions before trying their own.
• Printable PDF: Handy for independent study or when working through class examples.

This resource acts as a reference tool. Students who master substitution have a powerful mathskill at their fingertips.
