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 {{}} operator is used to compare one value to another.

The logical expression 'AND' returns True when...

The logical expression 'OR' returns True when...

Logical operators and comparison operators can be combined to build complex {{}}.

Which block is used to carry out selection in Scratch?

Which operator block would you use to check if the value of the score variable is 10?

Which of these blocks would you use if you want an operation to happen if the expression evaluates as False?

In which block category can you find the if block?

In which block category can you find this block?
