## Prior learning/place of lesson in scheme of work
|
|||
|
|
|
|||
|
|
Learn how to **plot image** by turning on a series of LED lights on the LED screen. We will be learning how to create a blinking app using a forever loop as well as simple commands, such as plot image, pause, and clear screen.

## What the teacher needs to know / QuickStart Computing Glossary
|
|||
|
|
|
|||
|
|
**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
