I work as a ta in a y1 class and often do guided reading grous, as well as the class teacher.
What resources do you use?
the guided reading books at school. Each set has between 3 and 6 books so sometimes we have to share. They are colour coded for ability. Some have envelopes attched to them witht he key words fromt he book in. Some sets have a teacher's guide in.
How long is a session?
10-20 minutes per group. Depends on the children, reading ability, etc.
What do the rest of the class do while you are with a reading group?
Often working on other activities at their tables/work areas. May also be during free chosing time. Generally one of us does the reading and the other supports the class.
How often do you do it?
Once a week per group.
Do pupils complete linked activities?
Rarely in our case
Is it all oral discussion?
Generally yes.
How do you use it for assessment?
Class teacher does this generally and uses other reasources too for checking reading ability. However it we notice a child is reading a book easily we discuss it, check them individually and then move them on.
