Sequencing How to get better

Getting better – Level 3 Putting Instructions in a Sequence You can put instructions into a sequence You understand that the sequence of instructions makes a difference to the final result

This cell tells you how much you have spent all together Changing these numbers will change the way the shape appears Instructions in a sensible sequence

Getting better – Level 4 Creating loops in the sequence You can make the sequence repeat rather than retyping it You make decisions in you sequence You create your instructions into a group (procedures)

‘Forever’ is a looping instruction The ‘If’ instruction checks something and makes a decision

Getting better – Level 5 Being Precise You notice small errors and make suitable adjustments. You test and improve your work (keeping earlier versions). You can explain why sequencing is important in the wider world.

Make sure the helicopter is facing the right way Change the values to make the helicopter fly faster

Getting better – Level 6 Making several ‘blocks’ of commands (Sub Procedures) You divide the problem into small blocks and then create the sequence for each ‘sub’ problem (sub procedures). You find efficient ways to make things happen.

The main program is small Sub Procedures manage small parts of the problem
