## Class
Year 7
## 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 math->random, and show number.

## Objectives
* learn how to run code when an input button is pressed
* learn how a variable is a place where you can store data
* learn how to set the value of a local variable
* learn how to returns a random number
* learn how to show a number on the LED screen, one digit at a time (scrolling left to right)
* learn how to turn off all the LED lights on the LED screen
## 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)
Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
