To start with, unplugged strategies work well for students to explain their thinking/understanding in programming. When working collaboratively, this usually involves students giving a set of instructions for other students to follow. These can involve physical activities or recipes, such as the making sandwich example, or it could involve a game scenario on paper. A good beginner’s game involves writing sets of arrows as the instructions for students to color in squares on a piece of grid paper. These kinds of unplugged activities help the students’ computational thinking as they begin to see sequential activities or sets of instructions in terms of algorithms.
