Exploring Physical Computing with the micro:bit for 3-5

This set of BBC micro:bit activities is perfect for introducing upper elementary students (grades 3–5) to physical computing and coding through hands-on, engaging projects. These activities are ideal for a STEM unit, coding unit, or CS rotation.

Target Audience: 3-5

What’s Included:

  • Activity 1 (Grades 3-5): Introducing the BBC micro:bit – In this activity we are going to explore the hardware of a micro:bit. Students will be introduced to physical hardware of the micro:bit and sensors, identifying opportunities for input and outputs. 
  • Activity 2 (Grade 3-5): Animated Animals – In this activity you will explore how to create a simple animation on the BBC micro:bit’s LED display by coding an animation on the MakeCode platform. By using code blocks with built-in icons and custom modifications, students will learn to program the micro:bit to a two sequence animation.
  • Activity 3 (Grade 3-5): Wearable Step Counter – Turn your BBC micro:bit into a step counter (or pedometer) to help you track how active you are – and learn some coding at the same time!
  • Activity 4 (Grade 2): Code.org micro:bit Maker – Bring hands-on technology learning to Computer Science with the code.org Maker course, designed around the micro:bit physical computing device. With courses specific to each grade (3, 4, and 5), these courses bridge the gap between digital and physical worlds, enabling students to transfer their computer programs into real-world applications with the micro:bit. Students will learn fundamental coding principles such as sequencing, loops, conditional logic, and event handling, and they will gain practical experience in how hardware and software can work together.
