Reorganisation for reading

Today in room 9 we did reorganisation for reading it is like when you are related to something or some one and you get separated but still related to that thing or someone, For example if you have a sister that goes to school or work with you they  are related to when you go to school but then when you get to school you go to 1 class and they go to the other class.  So you  guys are separated but still related and so now you know what reorganisation.
