N It is an important part of problem solving because, if you can identify similarities between two different problems, you might be able to apply the same or a slightly S modified solution to both problems. This enables computer programmers to work efficiently, L solving problems more quickly and writing less code.

When you were identifying patterns in the original flower, N you were decomposing the flower and carrying out pattern recognition. When you made a list of elements that could be removed S or changed and still leave a recognisable flower design, you were carrying out abstraction. When you were identifying the similarities and differences L between the flowers, you were carrying out pattern recognition. Computational thinking will help you create an algorithm E for drawing the abstracted flower, an algorithm that could then be adapted to draw an infinite number of different flowers.

Modules are small chunks of code that perform a discrete task. In Logo, N these chunks of code are called ‘procedures’. They are called on by the main program when needed. Modularity brings a number of important benefits to the programmer. S A module can be used many times within a single program. A module can be used in more than one program. A module can easily be changed to do something similar but slightly different. L Code written in modules is easier to read and debug than a single long sequence of code. Modules are more efficient for the programmer to write because they use fewer lines of code.
