Lesson 1: From blocks to text

Before starting this unit, check that the children can recall:

• Programs can be explored and tested on the BBC micro:bit to see how they work.

• Predicting code means thinking about what it will do before running it.

• Inputs, variables and conditions make programs interactive.

• Sensor data, such as from pedometers or weather checkers, can control what a program does.

• Programs can respond to real-time readings from sensors.

• Debugging means finding, fixing and improving code to make it work correctly.
