Diwali Lights: Loops and Repeat | Year 4 Computing PowerPoint Lesson

Light up your Computing lesson with this visual, colourful and interactive Year 4 PowerPoint, using Diwali, the festival of light, as the context for learning about loops. Pupils see why repetition makes programs shorter and more efficient, write count-controlled loops, trace code step by step and debug common errors such as the wrong count or a missing instruction. The ready-to-teach, no-prep deck is written to the child and read aloud by the teacher, with correct computing vocabulary (algorithm, sequence, repetition, loop, debug). A hands-on unplugged activity has pupils act as the robot on a grid, and a creative task has them plan and code a rangoli-style pattern of lights, which can be built in any block-based coding tool. The Diwali content is respectful and accurate, and the context supports an RE and Computing link in autumn. Ideal for a seasonal Computing lesson, a cover lesson or a cross-curricular festival week. Includes a ‘Where this leads next’ slide pointing to Year 5 selection and variables.
