With ScratchJr, young children (ages 5-7) learn important new skills as they program their own interactive stories and games. By snapping together graphical programming blocks, children can make characters move, jump, dance, and sing. In the process, children learn to solve problems, design projects, and express themselves creatively on the computer. They also use math and language in a meaningful and motivating context, supporting the development of early-childhood numeracy and literacy. With ScratchJr, children don’t just learn to code, they code to learn. ScratchJr was inspired by the popular Scratch programming language (http://scratch.mit.edu), used by millions of people (ages 8 and up) around the world. The ScratchJr interface and programming language were redesigned to make them appropriate for younger children’s cognitive, personal, social, and emotional development. ScratchJr is a collaboration between the Lifelong Kindergarten research group at the MIT Media Lab, the Developmental Technologies research group at Tufts University, and the Playful Invention Company. The ScratchJr project has received generous financial support from the National Science Foundation (NSF DRL-1118664), Scratch Foundation, LEGO Foundation, and British Telecommunications. If you enjoy using this free app, please consider making a donation to the Scratch Foundation (www.scratchfoundation.org), a nonprofit organization that provides ongoing support for ScratchJr. We appreciate donations of all sizes, large and small.

A STEM educational game for kids to develop Computational Thinking as fundamental skills for future learning and problem solving. 【What is Computational Thinking?】 Computational Thinking (CT) helps us to analyze and solve problems in a logical and systematic way, just like how computer scientists solve problems with programming. Developing a computational thinking mindset is more fundamental and important than learning coding at a young age, and will facilitate learning programming languages such as Scratch, Python, C++ or JavaScript. CT applies not only to programming, but also to problem solving in everyday life. 【What is Coding Galaxy Adventure?】 Coding Galaxy Adventure is a fun and challenging coding game for kids and beginners to learn basic programming concepts and develop computational thinking skills. As a member of the Galaxy Union, you are tasked with saving the polluted planets by solving block-coding puzzles. An exciting adventure awaits! 【What will your kids learn from Coding Galaxy Adventure?】 - Familiarize with basic programming concepts (sequences, loops, conditionals, control flow, debugging) - Develop and apply computational thinking using concepts (decomposition, evaluation, pattern recognition, algorithm design) - Build up problem-solving skills - Improve spatial abilities 【Why choose Coding Galaxy Adventure?】 - Learning content and methodology based on Coding Galaxy, an award-winning CT teaching and learning solution - Over 100 missions spread across 5 worlds to solve with a variety of obstacles and tools - Character customization with different appearances and dressing styles - Explicit learning objectives and explanations - Learning progress report for parents ------- Follow us on Facebook: http://www.facebook.com/CodingGalaxyApp/ To learn more, visit http://codinggalaxy.com
