## Prior learning/place of lesson in scheme of work
|
||
|
|
|
||
|
|
Learn how to create numbers randomly by using the input of the BBC micro:bit. We will be learning how to create random numbers with input using a local variable as well as simple commands, such as pick number and show number.

## 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)
|
||
|
|
|
||
