Unit of 5 lessons aimed at pupils KS2 Year 6 in England( ages 10-11). They are introduced to variables and develop their understanding through a mixture of unplugged and practical programming activities. Pupils design and program the micro:bit to be a star-jump and step counter and a family activity selector. The sequence comprises 5 lessons of approximately 60 minutes each: Describing with variables Using variables in algorithms and programs Analysing, programming and evaluating step-counters Planning to get active Programming and evaluating a family activity picker . Learning objectives can understand and apply the fundamental principles and concepts of computer science, including abstraction, logic, algorithms and data representation have repeated practical experience of writing computer programs in order to solve problems can evaluate and apply information technology are responsible, competent, confident and creative users of information and communication technology . Additional skills Creative thinking, collaboration, problem-solving, debugging, evaluation. Supplied resources Lesson plans (Word) Lesson slides (PowerPoint) Student handouts Sample micro:bit program files .

Unit of 5 Computing & Science lessons aimed at KS2 Year 4 in England (ages 8-9). Pupils develop their understanding of flowchart algorithms, selection and inputs and outputs by using electrical circuits and the BBC micro:bit to test the conductivity of different materials. The unit comprises 5 lessons of approximately 60 minutes each: Unplugged lesson building electrical circuits and testing materials Unplugged lesson exploring selection and flowchart algorithms Tinkering with inputs on the micro:bit using the MakeCode editor Electrical conductivity testing with the micro:bit Unplugged review, decomposing learning in the unit .
