+## Objectives
+
+* learn how to repeat code a fixed number of times
+* learn how to turn on a LED light on the LED screen. Specify with LED using x, y coordinates
+* learn how to turn off a LED light on the LED screen. Specify which LED which x, y coordinates
+* learn how to pause program execution for the specified number of milliseconds
+
+## 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
