Tools at home make life easier. Build a spinning fan and a pretend phone with Cubroid blocks!
Tools at home
Notes for teachers
Grades 1–2, about 2 lessons (fan + pretend phone). Adapted from a Busan Office of Education summer program lesson. No AI in this lesson: it is a first coding lesson.
Class promises: 1) Join in and have fun. 2) Say “I can do it!” and “Please help me.” 3) Stop the motor before touching spinning parts. 4) Put the blocks away when you finish.
Which tools do we use at home?
Let's name them together!
What if we had no household tools?

How does a fan work?
- 1. ElectricityElectricity makes the motor go.
- 2. BladesThe spinning blades move the air.
- 3. WindMoving air feels cool on our skin.
