Objectives

  • learn how to repeat code a fixed number of times
  • learn how to turn on a LED light on the LED screen. Specify with LED using x, y coordinates
  • learn how to turn off a LED light on the LED screen. Specify which LED which x, y coordinates
  • learn how to pause program execution for the specified number of milliseconds

Progression Pathways / Computational Thinking Framework

Algorithms

  • Uses logical reasoning to predict outputs, showing an awareness of inputs. (AL)
  • Understands that iteration is the repetition of a process such as a loop. (AL)
  • Represents solutions using a structured notation. (AL) (AB)

Programming & Development

  • Creates programs that implement algorithms to achieve given goals. (AL)
  • Uses a variable and relational operators within a loop to govern termination. (AL) (GE)
  • Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL)

Data & Data Representation

  • Understands the difference between data and information. (AB)
  • Defines data types: real numbers and Boolean. (AB)

Information Technology

  • Collects, organises and presents data and information in digital content. (AB)
  • Makes appropriate improvements to solutions based on feedback received, and can comment on the success of the solution. (EV)

Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
