flashing heart lesson plan

Learn how to create LED images with a variable.

@video vimeo/134118661

Topic

Global Variable - Blinking Images

Class

Year 7

Prior learning/place of lesson in scheme of work

Learn how to control a blinking LED image. We will be learning how to create a blinking app using global variables, forever as well as simple commands, such as create image, show image, pause, and clear screen.

What the teacher needs to know

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.**

Algorithm: An unambiguous set of rules or a precise step-by-step guide to solve a problem or achieve a particular objective. The guided tutorial follows a algorithm and is a precise step-by-step guide to solve a problem**

Loop: A block of code repeated automatically under the program’s control. ** The blink program introduces Forever. Forever will repeats code in the background forever.

Command: An instruction for the computer to execute, written in a particular programming language.**

Progression Pathways

Computational Thinking Framework

Algorithms

  • 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)

Data & Data Representation

  • Understands the difference between data and information. (AB)
  • Defines data types: real numbers and Boolean. (AB)

Information Technology

  • Collects, organises 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)

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