Problem solving using programming constructs

Computing

Sequence

Program variables

Selection

Operators

Count-controlled iteration

In this unit pupils will build their confidence and knowledge of the key programming constructs (sequence, iteration, selection and variables). Learners will use Scratch to explore the key programming constructs firstly through editing pre-existing code and then by developing their own programs.

Using fundamental programming constructs in a block-based language

The three main programming constructs are sequence, selection and {{}}.

Breaking a large problem down into smaller, more manageable parts is known as ...

Which programming construct is used in this code block?

Which of these instructions is not a subroutine?

In computing, repeatedly executing instructions is known as ...

{{}} is the process of finding an error in your code and taking steps to fix the problem. 

What is repeatedly running a sequence of instructions a set number of times known as?

What value would be held by the ‘name1’ variable and the ‘name2’ variable at the end of this program?

When the value of a variable is updated in a program, it's previous value is ...
