Help with intervention for kindergartener?

I have a kindergartener who is having issues related with finishing his work and writing neatly.

I think he may have some fine motor skill issues. But the real issue is that he has a fit if he's not done with his work or if something is not 'neat' in his opinion. He's like a perfectionist.

The other day I was observing him doing an assignment where he was supposed to be copying sight words. He was supposed to write the word 'yes' and he began to write his 'y' too far to the right of the line provided for him. He realized immediately that there would not be enough room to write the entire word. He began to get upset and cry. I quickly told him to just scratch out the 'y' and start farther over to the left and re-write the word. He dealt with this OK...but his teacher said that normally that type of situation would lead to a fit with him.

He also has issues when they do their morning work. They are given lots of time and he is given warnings throughout that there is a time limit....however he often is distracted from his work and when the timer goes off and he's not finished and is asked to put it away, he gets upset because he's 'not finished'.

Any ideas of what I can suggest to the teacher to help her out?
