This is background information about ScratchJr. You can find answers to troubleshooting questions in the "FAQ" section.
What is ScratchJr?
ScratchJr is an introductory programming language that enables young children (ages 5-7) to create their own interactive stories and games. Children snap together graphical programming blocks to make characters move, jump, dance, and sing. Children can modify characters in the paint editor, add their own voices and sounds, even insert photos of themselves -- then use the programming blocks to make their characters come to life.
ScratchJr was inspired by the popular Scratch programming language (http://scratch.mit.edu), used by millions of young people (ages 8 and up) around the world. In creating ScratchJr, we redesigned the interface and programming language to make them developmentally appropriate for younger children, carefully designing features to match young children's cognitive, personal, social, and emotional development.
ScratchJr is available as a free app for both iPad and Android tablets. For more information about ScratchJr, see http://scratchjr.org.
Why Did We Create ScratchJr?
Coding (or computer programming) is a new type of literacy. Just as writing helps you organize your thinking and express your ideas, the same is true for coding. In the past, coding was seen as too difficult for most people. But we think coding should be for everyone, just like writing.
As young children code with ScratchJr, they learn how to create and express themselves with the computer, not just to interact with it. In the process, children learn to solve problems and design projects, and they develop sequencing skills that are foundational for later academic success. They also use math and language in a meaningful and motivating context, supporting the development of early-childhood numeracy and literacy. With ScratchJr, children aren't just learning to code, they are coding to learn.
Who Created ScratchJr?
ScratchJr is a collaboration between the Developmental Technologies (DevTech) Research Group at the Eliot-Pearson Department of Child Study and Human Development at Tufts University (led by Marina Umaschi Bers, with contributions from Amanda Strawhacker, Claire Caine, Louise Flannery, Elizabeth Kazakoff and Dylan Portelance), the Lifelong Kindergarten group at the MIT Media Lab (led by Mitchel Resnick, with contributions from Chris Garrity, Tim Mickel, Carl Bowman, Champika Fernando, Natalie Rusk, Sayamindu Dasgupta, and Chris Graves), and the Playful Invention Company (led by Paula Bontá and Brian Silverman, with contributions from Jack Geddes and Adrian Gabriel). The Android version of ScratchJr was implemented by Two Sigma (led by Mark Roth, with contributions from Kevin Hu), with input from Benesse Corp.
The graphics and illustrations for ScratchJr were created by HvingtQuatre Company (led by Julien Gelifier and Adrien Valesa), Sarah Thomson, Peter Mueller, and Jillian Lombardi. Paula Aguilera of the MIT Media Lab produced the ScratchJr video. We would also like to thank everyone who participated in the beta-test communities for iPad and Android, particularly Sergio Antolinez, Vandendaele Didier, and Sjoerd Dirk Meijer.
Who Supported ScratchJr?
The ScratchJr project has received generous financial support from the National Science Foundation (NSF DRL-1118664), Scratch Foundation, LEGO Foundation, British Telecommunications, and Adobe Systems.

Frequently Asked Questions
Find answers to your troubleshooting questions here.
Will ScratchJr run on my iPad or tablet?
ScratchJr runs on both iPads and Android tablets. It will run on any iPad 2 or later, including all iPad minis, with iOS 7.0 or later installed. It also runs on any Android tablet, 7-inches or larger, that are running Android 4.2 (Jelly Bean MR1) or higher. It does not need web-access to run.
Is there a book for ScratchJr?
Yes, there is a guide to ScratchJr. Written by app creators Professor Marina Umaschi Bers and Mitchel Resnick of the Lifelong Kindergarten Group at the MIT Media Lab, this new book is an easy-to-use, hands on resource for parents and educators alike to teach children how to code with ScratchJr. Read an excerpt of the book. You can buy your copy through No Starch Press!
Are you planning to release a Web version of ScratchJr?
We are still in the early planning stages for a Web version.
Can I share a ScratchJr project from one tablet to another?
If you are running ScratchJr version 1.0.3 or greater on the iPad, you can share projects via email or AirDrop. To access the sharing options, go to the Project Information page by tapping on the yellow button in the top-right corner of the ScratchJr editor.
Project sharing will become available on Android tablets in version 1.1.
Project sharing will become available on Android tablets in version 1.1.
Why can't ScratchJr record a sound or take a picture
If ScratchJr can't record sounds or take a picture with the camera, it might be that you didn't give ScratchJr access to the camera or microphone when you first downloaded the app. You can change this by going to Settings > Privacy > Camera on your device. If the ScratchJr toggle is off, turn it on. Do the same for the microphone, under Settings > Privacy > Microphone
Will ScratchJr be available in other languages?
We hope to include translations in a future version of ScratchJr. If you're interested in volunteering to help with translations, please email email@example.com with your name and the language you can help with.
