die roll lesson

create a die on the BBC micro:bit.

Topic

If (Conditionals)

Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to use an if statements to run code run code depending on whether a condition is true or not. We will be learning how to create a die with If statements, On Shake, Variables, Assignment Operator, Pick Random and Show LEDs

Documentation

Objectives

  • learn how to run code when the BBC micro:bit is shaken, when running code in the web browser, moving the mouse quickly simulates shaking
  • learn how to create a local variable as a place where you can store and retrieve data
  • learn how the assignment operator is used to declare a new local variable
  • learn how to declare a new local variable or update the value of a variable
  • learn how to return a random number
  • learn how to conditionally run code depending on whether a condition is true or not
  • learn how to show an image on the LED screen

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 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)

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