## Prior learning/place of lesson in scheme of work
|
||
|
|
|
||
|
|
Learn how to use an if statement to run code run code depending on whether a condition is true or not. We will be learning how to create the game truth or dare using input an if statement, a local variable, math random as well as simple commands, such as show string and show LEDs.

## 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)
|
||
|
|
* Uses logical reasoning to predict outputs, showing an awareness of inputs (AL)
|
||
|
|
* Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB)
|
||
|
|
* 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 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
|
||
|
|
|
||
|
|
#### Hardware & Processing
|
||
|
|
|
||
|
|
* Knows that computers collect data from various input devices, including sensors and application software (AB)
|
||
|
|
|
||
|
|
Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
