Topic

While Loop

Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to creating a while loop, while condition do to repeat code while a condition is true. We will be learning how to create a digi yoyo app using a while loop, a variable, as well as basic commands, such as pause and show number.

Objectives

  • learn how to create a local variables to store data and use it in your code
  • learn how to set or change the value of a local variable
  • learn how to repeat code while a condition is true
  • learn how a relational comparison (<) of numbers will yield a Boolean
  • learn how to pause your code for the specified number of milliseconds
  • learn how to show a number on the LED screen

Progression Pathways / Computational Thinking Framework

Algorithms

  • Uses diagrams to express solutions.(AB)
  • Recognises that different solutions exist for the same problem (AL) (AB) Understands that iteration is the repetition of a process such as a loop (AL)
  • Recognises that different algorithms exist for the same problem (AL) (GE)
  • Represents solutions using a structured notation (AL) (AB)
  • Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE)

Programming & Development

  • Creates programs that implement algorithms to achieve given goals (AL)
  • Declares and assigns variables(AB)
  • Uses a variable and relational operators within a loop to govern termination (AL) (GE)
  • Selects the appropriate data types(AL) (AB

Data & Data Representation

  • Uses filters or can perform single criteria searches for information.(AL)

Communication Networks

  • Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns Understands how search engines rank search results (AL)

Information Technology

  • Collects, organizes, 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)
  • Recognises ethical issues surrounding the application of information technology beyond school.

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