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

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

Which of these is the less than operator block?

Which block is used to carry out selection in Scratch?

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

A {{}} is a named piece of data, stored in a memory location in a computer.

A variable can hold __________ one value at a time.

Which category of code block do you need to create a subroutine?

Which block would you use to update the value of the temperature variable in Scratch?

What is the value of temperature at the end of this block of code?
