Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to creating conditionals, if condition do to conditionally run code depending on whether a condition is true or not. We will be learning how to create a fortune telling app using local variable and conditionals (If), input on shake as well as simple commands, such as show string, show number, and clear screen.

Objectives

  • learn how to show a string on the LED screen
  • learn how to show a number on the LED screen
  • learn how to learn how to turn off all the LED lights on the LED screen
  • learn how to use the input on shake
  • learn how to learn how to create a local variable to store data so that you can use it later in your code
  • learn how to learn how to return a random number
  • learn how to learn how to conditionally run code depending on whether a condition is true or not

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)
  • 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)

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)
  • 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.

Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
