## Class
Year 7
## Prior learning/place of lesson in scheme of work
Learn how to get the acceleration **acceleration** , `input->acceleration` value (g-force), in one of three specified dimensions. We will be learning how to get the acceleration using forever loop, a local variable, acceleration, the math library, as well as simple commands, such as led set brightness and led plot all.

## Objectives
* learn how to repeat code in the background forever
* learn how create a local variable to store data, so that you can use it in your code
* learn how to get the acceleration value (g-force), in one of three specified dimensions
* learn how to return the absolute value
* learn how to sets the brightness of the LED screen
* learn how to turn on all the LED lights on the LED screen
## Progression Pathways / Computational Thinking Framework
#### Algorithms
* Uses diagrams to express solutions.(AB)
* Uses logical reasoning to predict outputs, showing an awareness of inputs (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)
* Uses a variable and relational operators within a loop to govern termination (AL) (GE)
* 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)
#### Hardware & Processing
* Knows that computers collect data from various input devices, including sensors and application software (AB)
#### 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
