Draggable item		Corresponding Item
Pseudocode		A method of solving a problem logically – to think and act like a computer
Decomposition		The instructions or steps required to solve a problem and program the actions a computer takes
Debugging		Breaking an algorithm into smaller, more manageable parts
Pattern recognition		Focusing on what is important, ignoring or removing any detail that is not necessary to the core algorithm
Algorithm		Looking for similarities and trends in computer programs and algorithms
Abstraction		Shows the flow and direction of the steps of an algorithm in a visual way
Computational thinking		Shows each step of an algorithm in a clearly ordered, written structure using a generic standard format - which can then be written into any programming language
