+## Prior learning / place of lesson in scheme of work
+
+Learn how to **ring** the buzzer to turn on the sound. We will be learning basic comments such as ring and clear screen.

+* learn how to run code when an input button is pressed
+
+## 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)
+* Recognises that different algorithms exist for the same problem (AL) (GE)
+* Represents solutions using a structured notation (AL) (AB)
+
+#### Programming & Development
+
+* Creates programs that implement algorithms to achieve given goals (AL)
+* Selects the appropriate data types(AL) (AB
+
+#### Data & Data Representation
+
+* Understands the difference between data and information(AB)
+
+#### Hardware & Processing
+
+* Understands the difference between hardware and application software, and their roles within a computer system (AB)
+
+#### Communication Networks
+
+* Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns (AL)
+
+#### 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)
+
+Computational Thinking Concept: AB = Abstraction; DE = Decomposition; AL = Algorithmic Thinking; EV = Evaluation; GE = Generalisation
