When I grade 2 in Vietnam. In-school math teacher taught us how to add operations. After training is complete, the teacher asks: If you add 1 to 5, will be? The class was silent.
The teacher said:
- For example, I give you 5 pigeons, then add one more child. You will have many pigeons?
- I stood up reply 7
surprising teacher asked: Why seven? Why?
- I explain:
- sir, I have one at home pigeons then, sir!
