## Prior learning/place of lesson in scheme of work
|
||
|
|
|
||
|
|
Learn how to creating **conditionals**, `if condition do` to conditionally run code depending on whether a condition is true or not. We will be learning how to create a fortune telling app using local variable and conditionals (If), input on shake as well as simple commands, such as show string, show number, and clear screen.

## Progression Pathways / Computational Thinking Framework
|
||
|
|
|
||
|
|
#### Algorithms
|
||
|
|
|
||
|
|
* Designs solutions (algorithms) that use repetition and two-way selection, ie if, then and else.(AL)
|
||
|
|
* 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)
|
||
|
|
* 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)
|
||
|
|
* Understands the difference between, and appropriately uses if and if, then and else statements(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)
|
||
|
|
* Selects the appropriate data types(AL) (AB
|
||
|
|
|
||
|
|
#### Data & Data Representation
|
||
|
|
|
||
|
|
* Understands the difference between data and information(AB)
|
||
|
|
* Performs more complex searches for information e.g. using Boolean and relational operators(AL) (GE) (EV)
|
||
|
|
* Defines data types: real numbers and Boolean (AB)
|
||
|
|
|
||
|
|
#### Hardware & Processing
|
||
|
|
|
||
|
|
* Knows that computers collect data from various input devices, including sensors and application software (AB)
|
||
|
|
|
||
|
|
#### 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
