description ScratchJr Overview
Built for children aged five to seven, ScratchJr introduces programming through visual blocks rather than typed commands. Children connect blocks to make characters move and respond within interactive stories and simple games. The emphasis on storytelling gives coding a clear purpose, letting learners experiment with an idea and see how changing a sequence changes what happens on screen. The free app is available across supported tablets and Chromebooks, and its source code is publicly available.
Drawing and sound tools make personal expression part of the activity rather than treating programming as an isolated exercise. It suits early-years classrooms and guided learning at home, especially where reading and typing skills are still developing. ScratchJr offers an introduction to computational thinking without requiring knowledge of programming syntax.
help ScratchJr FAQ
What age group is ScratchJr designed for?
ScratchJr is an introductory programming language specifically designed for young children ages 5 to 7. It allows early elementary students to create their own interactive stories and games before they are old enough to use the standard Scratch platform.
Do kids need to know how to read to use ScratchJr?
No, ScratchJr does not require any reading skills, making it perfect for kindergarteners and early readers. Instead of text, children snap together graphical programming blocks to dictate how their characters move and interact.
Who developed the ScratchJr app?
ScratchJr was developed through a collaboration between the DevTech Research Group at Tufts University, the MIT Media Lab, and the Playful Invention Company. It was financially supported by a grant from the National Science Foundation.
