In this lesson, learners of all ages get an introductory experience with coding and computer science in a safe, supportive environment. This lesson has two versions. This version uses drag-drop blocks and works best for students on mobile devices without keyboards, younger students, and international students. It is recommended for ages 6+.
A JavaScript version is also available. For older students on computers, learning JavaScript can be fun and provide an additional challenge. Note that JavaScript syntax is not translated and for the first Hour of Code, the translated blocks found here provide a better introduction. This version of the tutorial is also great if you have some students in your class who have already learned some coding. It is recommended for ages 11+.
Purpose
This lesson introduces the core CS concepts of coding and programming including sequencing and events. The JavaScript version of the tutorial also lets the students experience typing code.
