## Class
Year 7
## Prior learning / place of lesson in scheme of work
Learn how to **Show LEDs** on the screen. We will be learning show animation, show LEDs and pause.
## Documentation
* **show animation** : [read more...](/microbit/reference/basic/show-animation)
* **show LEDs** : [read more...](/microbit/reference/basic/show-leds)
* **on button pressed** : [read more...](/microbit/reference/input/on-button-pressed)
## Objectives
* learn how to show a series of image frames on the LED screen, pausing the specified time after each frame
* learn how to plot an image to show an image on the micro:bit's LED screen
* learn how to run code when an input button is pressed
## 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)
* Recognises that different algorithms exist for the same problem (AL) (GE)
* Represents solutions using a structured notation (AL) (AB)
#### Programming & Development
* Creates programs that implement algorithms to achieve given goals (AL)
* Selects the appropriate data types(AL) (AB
#### Data & Data Representation
* Understands the difference between data and information(AB)
#### Hardware & Processing
* Understands the difference between hardware and application software, and their roles within a computer system (AB)
#### Communication Networks
* Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns (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)
Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
