In Year 4 we have been using Logo, a text-based computer programming language, to explore shape.  In this week’s lesson we started to use the power of repetition to help make the algorithms that we wrote as efficient as possible – and discovered that using spaces and punctuation correctly is really important when we are writing instructions for the Logo on-screen robot!  A key skill we are developing is ‘debugging’ – the process of finding and fixing the problems (or ‘bugs’) in our code.  This, together with persistence, is a very important part of computational thinking!
