Ratio and Proportion | Year 6 Maths PowerPoint Lesson

This resource introduces ratio notation, simplifying ratios, the difference between ratio and proportion, scaling recipes and sharing amounts in a given ratio. It is a ready-to-teach PowerPoint scaffold for an hour-long maths lesson on ratio and proportion. The lesson opens with a squash-mixing mystery that children solve once they can simplify ratios, then builds through worked examples to a ratio workout and a design-a-party-mix challenge. A real-world slide shows how chefs, builders and map makers use ratio every day.
