Lesson 3 of 6

Python

9-12 yrs, 11-14 yrs

Start learning about inputs and outputs using buttons and icons on the display.

Key learning:

  • I understand that inputs and outputs involve the flow of data in and out of computers. 
  • I can apply this knowledge to the micro:bit’s button inputs and display output.
  • I can write instructions in Python to make something happen when a button is pressed on the micro:bit.

Computer systems:

Input/output

Programming:

Text-based programming

Unit of work

First lessons with MakeCode and the micro:bit

A sequence of lessons that provide a pathway through six projects, ideal for getting started with the micro:bit. Students develop their use of some core computing concepts by coding and making practical projects including step counters, nightlights, and games.
