Lesson 5
Interactions
In this lesson, students examine sensing blocks as a way to detect interactions in a Scratch project. They are then introduced to conditions as statements that can only be true or false and conditionals as commands that run only if a statement is true. Through a code tracing activity, the class evaluates the need for some conditionals to be looped. Finally, students apply their learning to their own project by creating draggable objects for their matching game.
