# flipping bird lesson count the number of times the BBC micro:bit has been shaken. ### @video td/videos/flipping-bird-0 ## Topic Math - Modulo ## Quick Links * [tutorial](/microbit/lessons/flipping-bird/tutorial) * [quiz](/microbit/lessons/flipping-bird/quiz) * [quiz answers](/microbit/lessons/flipping-bird/quiz-answers) * [challenges](/microbit/lessons/flipping-bird/challenges) ## Class Year 7 ## Prior learning/place of lesson in scheme of work Learn how to return the **modulus**, `math->mod` to determine if you will plot image. We will be learning how to return the modulus by using a local variable, input on shake, if (conditional), modulo, as well as simple commands such as plot image. ## What the teacher needs to know / QuickStart Computing Glossary * Algorithm: An unambiguous set of rules or a precise step-bystep guide to solve a problem or achieve a particular objective. * Input: Data provided to a computer system, such as via a keyboard, mouse, microphone, camera or physical sensors. * Output: The information produced by a computer system for its user, typically on a screen, through speakers or on a printer, but possibly through the control of motors in physical systems. * Programmable toys: Robots designed for children to use, accepting input, storing short sequences of simple instructions and moving according to this stored program. * Program: A stored set of instructions encoded in a language understood by the computer that does some form of computation, processing input and/or stored data to generate output. * Repetition: Executing a section of computer code a number of times as part of the program. * Simulation: Using a computer to model the state and behaviour of real-world (or imaginary) systems, including physical or social systems; an integral part of most computer games. * Variables: A way in which computer programs can store, retrieve or change data, such as a score, the time left, or the user’s name. ## Documentation * **global variables** : [read more...](/microbit/js/data) * **on shake** : [read more...](/microbit/reference/input/on-gesture) * **if** : [read more...](/microbit/reference/logic/if) * **math modulo** : [read more...](/microbit/js/math) * **plot image** : [read more...](/microbit/reference/led/plot-image) ## Resources * Activity: [tutorial](/microbit/lessons/flipping-bird/tutorial) * Activity: [quiz](/microbit/lessons/flipping-bird/quiz) * Extended Activity: [challenges](/microbit/lessons/flipping-bird/challenges) ## Objectives * learn how to create a local variable as a place where you can store data, so that you can use it in your code, across functions, and in nested code blocks * learn how to run code when the micro:bit is shaken; when running code in the browser, moving the mouse quickly simulates shaking * learn how to conditionally run code depending on whether a condition is true or not * learn how to return the modulus * learn how to display an image on the BBC micro:bit's LED screen ## Links to the National Curriculum Programmes of Study for Computing ## 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) * Shows an awareness of tasks best completed by humans or computers (EV) * Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB) * Recognises that different solutions exist for the same problem (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) * Declares and assigns variables(AB) * Uses post-tested loop e.g.‘until’,and a sequence of selection statements in programs,including an if,then and else statement(AL) * Understands the difference between, and appropriately uses if and if, then and else statements(AL) * Uses a variable and relational operators within a loop to govern termination (AL) (GE) * Uses a range of operators and expressions e.g. Boolean, and applies them in the context of program control. (AL) * Selects the appropriate data types(AL) (AB #### Data & Data Representation * Understands the difference between data and information(AB) * Uses filters or can perform single criteria searches for information.(AL) * Performs more complex searches for information e.g. using Boolean and relational operators(AL) (GE) (EV) * Defines data types: real numbers and Boolean (AB) #### Hardware & Processing * Knows that computers collect data from various input devices, including sensors and application software (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) * Uses criteria to evaluate the quality of solutions, can identify improvements making some refinements to the solution, and future solutions (EV) * Recognises ethical issues surrounding the application of information technology beyond school.
