## Class
|
||
|
||
Year 7
|
||
|
||
## Prior learning/place of lesson in scheme of work
|
||
|
||
Learn how to control a blinking LED. We will be learning how to create a blinking app using the for loop as well as simple commands, such as plot and pause.
|
||
|
||
## 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 a While Loop. While Loop is a while loop that will repeat code forever while - true.
|
||
|
||
**Command:** An instruction for the computer to execute, written in a particular programming language.**

## Objectives
|
||
|
||
* learn how to blink a light
|
||
* create a for loop that will loop through each x-value, y-value from 0 to 4.
|
||
* learn how to pause the light on and off
|
||
* learn how to repeat turning on and off the light

## Progression Pathways / Computational Thinking Framework
|
||
|
||
#### Algorithms
|
||
|
||
* Uses logical reasoning to predict outputs, showing an awareness of inputs. (AL)
|
||
* 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)
|
||
* 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)
|
||
|
||
#### 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
