Rangoli Patterns and Symmetry | Year 4 Maths PowerPoint Lesson

Make symmetry beautiful with this visual, colourful, interactive Year 4 maths PowerPoint built around Diwali rangoli patterns. Pupils learn what a line of symmetry is, test it three ways, count lines of symmetry in squares, rectangles, triangles and regular polygons, and avoid classic misconceptions such as the rectangle diagonal. Worked examples show how to complete a pattern across a mirror line using the same-distance rule and how to reflect points using coordinates. Two hands-on activities, completing a half-finished rangoli and designing an original symmetrical one, put the maths into practice, and an always, sometimes, never reasoning task adds genuine challenge. Matched to the KS2 Year 4 geometry programme of study (symmetry and position), it includes a quick-fire check with answers and a where-this-leads-next slide. Ready-to-teach and no-prep, it is ideal for non-specialist teachers, Diwali week and cover lessons. 17 slides with Laura’s friendly speech-bubble prompts. British spelling throughout. Download once and use every year.
