Selection to control the flow in a program

Computing

The micro:bit

Sensing inputs

Conditional statements

Designing a step counter

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

a statement that can only be True or False

Which part of a program decides which instructions run based on a condition?

What does the “if” part of an if/then/else statement do?

deciding if it is raining before going outside

Match each example to the programming concept:

both the “then” and “else” parts always run

neither part runs unless the condition is True

the “else” part always runs, no matter what

only the part matching the condition runs

Which statement about if/then/else in programming is correct?

Order these actions for making a decision in code:

It allows testing without special equipment

What is a benefit of using an emulator when developing a program?

Put these steps in order for creating and running a program on a micro:bit:

What happens after you transfer a program to a controllable device?
