Yes, I agree with talking with the teacher. I'm sure you will, but be sure to approach her with the idea that you will support her in the classroom, and you know that he needs to do the work. At this age, if a child learns that he can tear up his work, and then doesn't have to do it, he has learned quite a lesson! When things get hard, students need to know that they need to do their best.
I understand that others have mentioned that your child may have a problem doing the work. Find out if the teacher thinks this is the case, or if your son is trying to find a way not to do the hard work. You'd be surprised what kids try when they don't want to do the work!
Tearing up his work is unacceptable. Even if you find out that there is a problem, he cannot be allowed to tear up his work. He should have to do the work again - at school if possible. You also don't want him to learn that if he tears up his work at school, he can do it with Mom's undivided attention at home.
Best of luck to you. It's a good thing that you and the teacher are communicating. Be sure to continue doing that. You and his teacher should work as a team to make sure he is learning as much as he can this year. Kindergarten is a great year for you to set up your expectations for your child as a student. Keep us posted!
