Introduction to loops
Creating clear and simple code makes fixing, or debugging, your code much easier and using loops to simplify your instructions is a great way to start writing efficient code. In this lesson get the class moving as they learn about loops through dance before moving on to create a drawing project using loops in Scratch.
