How can you apply the concepts of computational thinking to Maths? Mathematics is full of problem solving challenges which makes computational a vital skill to help improve your maths skills! Check out my poster for a range of ideas on how to apply the concepts of computational thinking to the subject of mathematics! *Computational Thinking is a skill set that can be used across the curriculum, not just within computer science! The logical approach to solving a problem means that its application can be used to develop and improve students ability to deal with difficult problems in a more rational way. The aim of my posters is to make you realise that many of the brilliant tasks that teachers facilitate week in, week out actually include computational thinking. It’s just a matter of making it more explicit!
