## Class
|
||||
|
||||
Year 7
|
||||
|
||||
## Prior learning/place of lesson in scheme of work
|
||||
|
||||
Learn how to create a **break**, `break` to exit a while or for loop before the loop is complete. We will be learning how to create a break using global variables, Boolean, If (conditionals), a While Loop as well as simple commands, such as show string, plot image, show number, and pause.

## Objectives
|
||||
|
||||
* learn how to create global variables to store data so that you can use it later in your code, functions, and in nested code blocks
|
||||
* learn how to use the variables to declare a new local Boolean variable that will have one of two possible values: true or false
|
||||
* learn how to run code when an input button is pressed
|
||||
* learn how to repeat code while a condition is true
|
||||
* learn how to exit a while loop before the loop is complete
|
||||
* learn how to conditionally run code depending on whether a condition is true or not
|
||||
* learn how to show a string on the LED screen one character at a time
|
||||
* learn how to turn on LED lights on the LED screen
|
||||
* learn how to show a number on the LED screen, one digit at a time
|
||||
* learn how to pause your code for the specified number of milliseconds
|
||||
|
||||
## 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 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)
|
||||
|
||||
#### 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
|
||||
|
||||
* 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)
|
||||
|
||||
#### Communication Networks
|
||||
|
||||
* 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)
|
||||
|
||||
#### 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.
