ScratchJr

ScratchJr is a visual programming language designed to introduce programming skills to children ages 5–7. The app is considered an introductory programming language. It is available as a free app for iOS, Android and Chromebook.

ScratchJr is a derivative of the Scratch language, which has been used by over 10 million people worldwide. Programming in Scratch requires basic reading skills, however, so the creators saw a need for another language which would provide a simplified way to learn programming at a younger age and without any reading or mathematics required.
