We will be learning how to create numbers using show number and pause. ## Documentation * **show number** : [read more...](/reference/basic/show-number) * **pause** : [read more...](/reference/basic/pause) ## Objectives * learn how to show a number on the LED screen, one digit at a time * learn how to pause program execution for the specified number of milliseconds ## Progression Pathways / Computational Thinking Framework #### Algorithms * Uses diagrams to express solutions.(AB) * Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB) * Understands that iteration is the repetition of a process such as a loop (AL) * Recognises that different algorithms exist for the same problem (AL) (GE) * Represents solutions using a structured notation (AL) (AB) * Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE) #### Programming & Development * Creates programs that implement algorithms to achieve given goals (AL) * Selects the appropriate data types(AL) (AB #### Data & Data Representation * Defines data types: real numbers and Boolean (AB) #### Hardware & Processing * Understands the difference between hardware and application software, and their roles within a computer system (AB) #### 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) * Recognises ethical issues surrounding the application of information technology beyond school. Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation ## Activity * time: 20 min. * [activity](/lessons/lucky-7/activity) * [tutorial](/lessons/lucky-7/tutorial) * [quiz](/lessons/lucky-7/quiz) ## Extended Activity * time: 20 min. * [challenges](/lessons/lucky-7/challenges) ## Homework * Extended Activity: [challenges](/lessons/lucky-7/challenges)
