Since I join at http://www.bosowabinainsani.sch.id/, I try not to share grammar in English lesson for kids.
Why?
Kids especially grade 1, 2, 3 they have base language or mother tongue is bahasa Indonesia. As a first language too, they are still making the good one while they should face a new language or second language namely English. What is matter if they have no good basic while they should learn the others like English. So that as a teacher, I try to put away the grammar and they are still learning with fun.
I just make them happy at first and give simple rule if they don't know yet.
For instance:
If a pupil doesn't know the strange word yet, please do what teacher has said.
"How do you say "tidur" in English?"
or
"How do you say "sleep" in Bahasa?"
