Zhe tears my flashcard

You can guess why he tore my card. He was upset, angry.
Today he didn't join us in the phonics class. I thought he would like some games, so i asked him to join during the game session.
Unexpectedly, he still refused to join and he tore my card to show his anger.
I have to keep reminding myself that "never ever force the kids to do the things they don't want to do."
After school, we have Smart class. Zhe also not cooperate at 1st, but he was better temper comparing to the morning class. He read to me, and he finished his worksheet as well.Do you know what I deal with him? "Promise me you'll finish your work after you play the puzzle, okay?"
