I have just dropped dd1 off to her year 4 class and went into talk to the teacher. A I'm standing there two brothers come in (one y4 other y6) and the older one said something to younger one and younger one hit him. They then just start beating seven bells out of each other!! Teacher grabs younger one and holds him back for all of 30 seconds and then let's go! Boys then are fighting outside classroom and children standing watching, telling teacher who replies "well their outside" 
He goes outside in the end and finally separates them and brings little one inside.
I have some issues with this teacher and do find him too soft, and often when I drop dd1 off half the boys in the class are outside as parents have dropped them off and then they have gone back out 
Do I have word with teacher or head?? This morning was horrible to watch and they nearly knocked me and another child flying.
