rotation animation lesson

Learn how to create images with a global variable and while loop.

Topic

While Loop

Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to create images that look like a rotating animation by using a while loop. We will be learning how to create a rotating animation using a global variable, while loop as well as simple commands, such as on button pressed and show animation.

Objectives

  • learn how to create a global variable for a place where you can store data, accessible across functions, and in nested code blocks
  • learn how to set or change the value of a global variable
  • learn how to repeat code while a condition is true
  • learn how to declare a global boolean variable to determine which code will execute next
  • learn how to run code when an input button is pressed
  • learn how to show a series of image frames on the LED screen
  • learn how to pause your code for the specified number of milliseconds

Progression Pathways / Computational Thinking Framework

Algorithms

  • 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)
  • Declares and assigns variables.(AB)

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)
