We will be learning basic comments such as show LEDs and pause. ## Documentation * **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 LEDs on the 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 ## Activity * time: 20 min. * [activity](/microbit/lessons/smiley/activity) * [quiz](/microbit/lessons/smiley/quiz) ## Extended Activity * time: 20 min. * [challenges](/microbit/lessons/smiley/challenges) ## Homework * Extended Activity: [challenges](/microbit/lessons/smiley/challenges)
