is a precise set of ordered steps which can be followed by a human or a computer to do a task

a named piece of data (often a number or text) stored in a computer’s memory which can be accessed and changed by a computer program

data that is sent to a program to be processed

the result of data processed by a computer

Designing a step counter

Computing

The micro:bit

Selection to control the flow in a program

Sensing inputs

Conditional statements

Making a step counter

This unit brings together all the four programming constructs: sequence, repetition, selection and variables whilst also utilising a physical device - the micro:bit. Pupils begin with a simple program to build and test and then take on three new projects, with each adding more depth and complexity.

Sensing movement with physical computing

Designing your program first helps you plan what it needs to do.

You should write your program before designing it.

Using algorithms makes programming easier.

Which statement is a common mistake when creating a program?

Match each example to the correct keyword.

a named piece of data that can be changed

What do we call a visual plan that shows the steps and decisions in a program using arrows and shapes?

What do we call a precise set of ordered steps that a computer or person can follow to solve a problem?

a light turning on when a button is pressed

Which of these is an example of an output?

Which symbol is an operator for ‘greater than’?

What could happen if you change the order of conditions in a selection statement?

Put these steps in order for using a condition in a program.
