Simplifying Algebraic Expressions | Year 7 Maths PowerPoint Lesson

Ready to teach tomorrow? This visual, colourful PowerPoint gives you a complete, ready-to-teach hour on simplifying algebraic expressions for Year 7 (11–12 year olds). This lesson introduces algebraic notation, like terms, collecting terms and substitution. It tackles common misconceptions such as 3a + 2 = 5a and the difference between 2x² and (2x)². Pupils meet worked examples, an error hunt and explain-why challenges that lead towards expanding brackets at GCSE. It is non-specialist friendly, so it works equally well for subject specialists and as a cover lesson, with clear explanations, worked examples and speech-bubble prompts that keep pupils thinking. Every slide is bright, consistent and uncluttered, with colour-coded icons that make key ideas easy to spot. It follows the KS3 National Curriculum with British spelling throughout. Just open, present and teach.
