## Class
Year 7
## Prior learning/place of lesson in scheme of work
Learn how to create game blocks to keep track of the current score. We will be learning how to create a game using the blocks called `add points to score`, `score` as well as simple commands such as on button pressed and show number.
## Documentation
* **game library**: [read more...](/microbit/js/game-library)
* **on button pressed** : [read more...](/microbit/reference/input/on-button-pressed)
* **show number** : [read more...](/microbit/reference/basic/show-number)
## Objectives
* 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 score 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)
