Problem solving using programming constructs

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

a named piece of data stored in a computer’s memory which can be accessed and changed by a computer program

the data a variable holds at a particular time

to track the value a variable holds at any time during a program

a combination of logical and comparison operators that result to True or False

used when there is more than one possible path for a program to follow

an operator that is used to compare one value to another

an expression that evaluates to True or False

an operator used in a logical expression, for example, AND, OR and NOT

the process of repeating a sequence of instructions within a program loop

a command that repeatedly runs a sequence of instructions a predefined number of times

a command that repeatedly runs a sequence of instructions until a condition is no longer being met

a situation or task that needs to be solved

breaking down a problem into smaller parts to make the task more manageable
