Learn how to create a charades game using **[arrays](/types/array)** to store and retrieve data. We'll learn how to create a charades game using global variables, a collection of strings, math add, Boolean, on logo down, on logo up, forever loop, if statements, running time as well as simple commands, such as show string and show number.
* Data: A structured set of numbers, possibly representing digitized text, images, sound or video, which can be processed or transmitted by a computer, also used for numerical (quantitative) information.
* Decomposing: The process through which problems or systems are broken down into their component parts, each of which may then be considered separately.
* 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.
* Script: A computer program typically executed one line at a time through an interpreter, such as the instructions for a Scratch character.
* Selection: A programming construct in which one section of code or another is executed depending on whether a particular condition is met.
* Sequence: To place program instructions in order, with each executed one after the other.
* 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.
* learn how a collection is a group of variables of the same type stored together
* learn how to create a global variable as a place where you can store data so that you can use it later in your code, accessible across functions and in nested code blocks
* learn how to repeat code in the background forever
* learn how to learn how to conditionally run code depending on whether a condition is true or not
* Designs solutions (algorithms) that use repetition and two-way selection, ie if, then and else.(AL)
* Uses logical reasoning to predict outputs, showing an awareness of inputs (AL)
* 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)
* Represents solutions using a structured notation (AL) (AB)
* Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns Understands how search engines rank search results (AL)
