Prior learning/place of lesson in scheme of work
Learn how to use the pins pin pressed, input->on pin pressed
to run code when the user holds the GND pin with one hand, and presses pin 0 with the other hand, thus completing a circuit. We will be learning how to create a love meter using input on pin pressed, a local variable, math random, If (conditional) as well as simple commands, such as show number, pause, and show string.

Objectives
- learn how to run code when the user holds the GND pin in one hand, and presses pin 0 with the other hand, thus completing a circuit; when you run a script with this function in a web browser, click pin 0 on the simulator
- learn how to a create a variable for a place where you can store and retrieve data
- learn how Boolean operators take Boolean inputs and evaluates to a Boolean output
- learn how to return a random number
- learn how to show a number on the LED screen
- learn how to pause your code for the specified number of milliseconds
- 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 (scrolling from left to right)
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)
- Designs solutions by decomposing a problem and creates a sub-solution for each of these parts. (DE) (AL) (AB)
- 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)
- 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)
- 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)
- Makes judgements about digital content when evaluating and repurposing it for a given audience (EV) (GE)
- 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
