About this lesson: An engaging computer science lesson that introduces students to the fundamental concept of binary numbers - the language computers use to store and process information. Learners explore how binary compares to the decimal system, gain an understanding of bits and bytes, and practise converting between number systems. Through interactive tasks and visual activities, students apply their knowledge to recognise binary patterns, represent data digitally, and complete a pixel art challenge. The lesson ends with a fun online game to reinforce concepts. This lesson builds essential coding, digital literacy, and problem-solving skills for robotics and computing pathways.
