Objectives
- learn how to create a variable as a place where you can store data so that you can use it later in your code, accessible across all functions, and in nested code blocks
- learn how arithmetic operators operate on numbers and return a number
- learn how to run code when an input button is pressed
- learn how to show a number on the LED screen, one digit at a time (scrolling from left to right)
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)
