In this Kapow Computing video, teachers are guided through a lesson that helps the pupils understand how procedures and loops can make algorithms more efficient.

The video demonstrates how procedures can be used to group commands, sometimes called ‘functions’ in block-based coding tools. An example shows how a sequence, such as walking, can be simplified into a single command, supporting the children to see that grouping instructions reduces repetition and makes code easier to manage. Loops are then introduced to repeat these grouped procedures, highlighting how both concepts work together to solve problems effectively.

This video is part of Kapow Primary’s Computing videos, supporting teachers to explain abstract coding ideas through real-life analogies and clear modelling.
