                                                                When a librarian arranges books alphabetically,

                                                                also use similar steps to sort a large number of
                                                                items very quickly. Sorting algorithms are one of

                                                                the most important tools in computer science.

                      There are so many other examples of using algorithm in real-life, like your morning

                      alarm, using a washing machine to clean clothes, playing a game by following rules,
                      sending a message on your phone, etc.

                       Explore the journey of cotton from farm to mill by first arranging these jumbled steps in the
                       correct order: picking, planting, growing, cleaning, transport, carding, spinning and weaving.
                       Once sorted, create a simple chart using pictures or arrows to show how cotton moves from

                       the farmer's field to the factory. Use different colours to highlight the three key roles — the
                       farmer who grows and harvests the crop, the transporter who delivers it to the mill and the mill
                       worker who cleans, spins and weaves it into cloth. Discuss with your classmates why each role
                       matters and what could go wrong if any step is skipped or done out of order. Finally, spot and
                       correct the errors in this mixed-up sequence: Weaving → Planting → Spinning → Transport →
                        Picking → Growing → Cleaning → Carding.
