Two methods for teaching this below
1, Moving Game using Scratch Junior (USE, MODIFY, CREATE)
Pupils use and modify (make small changes) to a copy of the game to answer questions before making their own game.
2, Moving Game using Scratch Junior (decomposition method)
Pupils watch a space game and then tell their teacher what it does (decompose it) before building it with the aid of the teacher. Finally they generalise the idea to make their own moving games independently or in pairs.
Computing Programs of Study Covered
Pupils should be taught to:
-understand what algorithms are; how they are implemented as programs on digital devices; and that programs execute by following precise and unambiguous instructions
-create and debug simple programs
-use logical reasoning to predict the behaviour of simple programs
-use technology purposefully to create, organise, store, manipulate and retrieve digital content
You will need to unzip the example and then email it to your tablet where it can be opened in Scratch Junior. I have only tested this on an iPad.
