Key stage 3
Pupils should be taught to:
  • design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems
  • understand several key algorithms that reflect computational thinking [for example, ones for sorting and searching]; use logical reasoning to compare the utility of alternative algorithms for the same problem
  • undertake creative projects that involve selecting, using, and combining multiple applications, preferably across a range of devices, to achieve challenging goals, including collecting and analysing data and meeting the needs of known users
  • create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability
  • understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct, and know how to report concerns
  • Key stage 4
    All pupils must have the opportunity to study aspects of information technology and computer science at sufficient depth to allow them to progress to higher levels of study or to a professional career. Pupils should be taught to:
  • develop their capability, creativity and knowledge in computer science, digital media and information technology
  • develop and apply their analytic, problem-solving, design, and computational thinking skills
  • understand how changes in technology affect safety, including new ways to protect their online privacy and identity, and how to report a range of concerns

    Class Presentations

    These student-facing slide presentations help educators seamlessly run Tynker lessons in a virtual or physical classroom setting. Each lesson has its own set of slides that introduce the big ideas, suggest unplugged activities, and include a section for each activity module. While running lesson slides, you can switch back and forth between the activity, the slides, answer keys and other lesson materials.
    A sample slide presentation is available for your review. Please log in to view all the class presentations available with your plan..
