Children can begin learning block-based coding as early as age 4 or 5, depending on their developmental readiness. At this stage, kids can understand simple sequencing, directions, and cause-and-effect relationships through visual, drag-and-drop activities. These early experiences help build logical thinking skills even before children can read or write fluently.
As children grow older, block-based coding becomes more structured and complex. By ages 7–10, students can work with loops, conditions, and variables using block-based tools, setting the stage for a smooth transition to text-based programming in later years. Because block-based coding adapts well to different ages and skill levels, it is one of the most effective ways to introduce computer science at a young age.
