π What is ScratchJr?
ScratchJr is an introductory programming language that enables children aged 5-7 to create their own interactive stories and games. Inspired by Scratch, but designed specifically for younger children, ScratchJr uses a simplified interface and block-based coding to make programming accessible and enjoyable.
π History and Background
ScratchJr was developed by the DevTech Research Group at Tufts University, the Lifelong Kindergarten Group at the MIT Media Lab, and the Playful Invention Company. It was released as a free app for iPad in 2014 and later for Android tablets. The goal was to provide a developmentally appropriate programming environment for young children who may not be ready for the more complex Scratch.
π Key Principles of ScratchJr
- π¨ Simplicity: ScratchJr uses a drag-and-drop interface with large, colorful blocks that are easy for young children to manipulate.
- πΆ Age-Appropriateness: The language and interface are designed to be developmentally appropriate for children aged 5-7, focusing on foundational programming concepts.
- βοΈ Storytelling: ScratchJr encourages children to create and share their own stories, fostering creativity and narrative skills.
- π€ Collaboration: The platform promotes collaborative learning, allowing children to work together on projects and share their creations.
- π± Touch-Based Interaction: Optimized for tablets, ScratchJr utilizes touch-based interaction, making it intuitive for young children to use.

- π© Testing Your Story:
- βΆοΈ Tap the full-screen button (top right) to test your story. Tap your character to see if it moves and speaks as programmed.
- πΎ Saving Your Project:
- πΎ Tap the back arrow to return to the project selection screen. Your project is automatically saved.
π‘ Tips for Enhancing Your Interactive Story
- π Multiple Characters: Add more characters and create interactions between them.
- π¬ Multiple Pages: Use the page buttons to create a multi-page story.
- βοΈ Message Passing: Use the "Send Message" and "Receive Message" blocks (orange category) to coordinate actions between characters and pages.
- π€ Record Your Voice: Use the record feature in the "Sound" block to add your own voice to the story.
