+Year 7
+
+## Prior learning/place of lesson in scheme of work
+
+Learn how to create **animation**, `basic->show animation` to display an animated image. We will be learning how to create an animated image using forever loop as well as simple commands, such as show animation.
+
+## Documentation
+
+* **show animation** : [read more...](/microbit/reference/basic/show-animation)
+* **forever** : [read more...](/microbit/reference/basic/forever)
+
+## Objectives
+
+* learn how to show a series of image frames on the LED screen, pausing the specified time after each frame
+* learn how to repeat code in the background forever
+
+## Progression Pathways / Computational Thinking Framework
+
+#### Algorithms
+
+* Uses diagrams to express solutions.(AB)
+* Represents solutions using a structured notation (AL) (AB)
+*  Can identify similarities and differences in situations and can use these to solve problems (pattern recognition)(GE)
+
+#### Programming & Development
+
+* Creates programs that implement algorithms to achieve given goals (AL)
+
+#### Communication Networks
+
+* Demonstrates responsible use of technologies and online services, and knows a range of ways to report concerns Understands how search engines rank search results (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
