+## Prior learning/place of lesson in scheme of work
+
+Learn how to `show LEDs` by showing an image on the LED screen. We will be learning how to create a blinking app using a forever loop as well as simple commands, such as show LEDs, pause, and clear screen.

+
+## Objectives
+
+* learn how to repeat code in the background forever
+* learn how to show LEDs on the LED screen
+* learn how to pause your code for the specified number of milliseconds
+* 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
