Ideas for teaching

First time teaching was in 2006, really really nervous in front of kids. The class was just like in chaos, some kids were playing under the table, the other one was on the table haha.. The teaching materials that I prepared were completely useless.
Suddenly I got an idea, we took the kids outside and I told them that the garden hadn't watered yet,
Let's watering the plants, hahaha kids really like to play with the water, incl watering plants. They took the jobs very seriously,
Even they were asking to me abt the plants' names. We didn't realize it already took an hour.So from that moment I always remember, took ideas from the nature, then the nature will finish the jobs by itself :)
