091. the jam sandwich algorithm: precise instructions (ks3)
Learn the importance of precise algorithmic instructions by trying to program a human to make a jam sandwich without causing a complete mess.
Have you ever tried to tell an alien how to make a jam sandwich? If you just say "put the jam on the bread", they might put the whole jar on an uncut loaf! Computers are just like that alien - they need extremely precise, step-by-step instructions. In this lesson, we will explore algorithmic thinking and learn why being specific is the most important skill a programmer can have.
