In computing we looked at how to program your teacher to make a jam sandwich. This is about the instructions and to be exact in every small instruction or algorithm.
Coding is telling a computer what to do, in a way that, with a bit of translation, it can understand. You give computers instructions in what is known as ‘code’, in a similar way to how you might have a recipe for how to cook something. You tell the computer about elements it needs to work with (like the ingredients), you give it instructions, and there might be some conditions it needs to choose between (like choosing whether an oven is electric or gas and then following the corresponding temperature). These instructions you give the computer need to be broken down into every single task, without ambiguity. It can take practice to think as a computer would so you can work out what instructions would need to be written.
