Howling, as a sample day (my dd is at an ABA school), dd will do:
arrive, and have registration (circle time: greet everyone, complete the register and talk through the day)
she has, on any single day, various groups (could be SALT group, OT group, handskills, topic work, etc). today she has topic work (they are working on nationality and identity. she will be making a flag as well as examining various object of cultural significance to each class member) and SALT group (she will be reading through her group book, and working on some of her SALT targets - to answer questions about the text and find points in the story to illustrate her answer). these groups can be from 3 children up to whole class (6 children), or may be mixed in the case of OT for eg, and made up of children from across classes, according to ability and activity.
in between, she will also work at her desk, with her tutor 1:1. she will work on literacy (at the moment concentrating on spelling in a variety of ways - handwriting, typing), numeracy (beginning column addition using 2 digit numbers, and working on monetary values), and may also practise things like a new board game to share at social skills group. she will also work on creating mind maps, to help with her SALT targets of widening vocabulary and increasing conversational ability.
as part of her conversation targets, she goes with her tutor to talk to less familiar tutors (dd finds conversation difficult, yet enjoys talking to people; increasing her repertoire of conversations means she can share with a greater variety of people; exposing her to less familiar tutors means she has to work at getting her meaning across in a better way, as these tutors will not 'know' dd and won't be able to compensate at all. naturally, she practises with her tutor first until she is comfortable, and the unfamiliar tutors have been primed so that the interaction can be a success)
she also has daily living skills to work on - she is 9, and so school are beginning to prepare for body changes and puberty. so she is learning about bodies, and about her own body. she also helps to clear up at lunch and snack times, and there is a rota to help with things like loading the dishwasher, or putting items away/wiping tables etc.
in OT group, she is working on motor skills via cutting, bike riding, and yoga!
her playskills targets include learning new tunes on the piano (she has mastered several so far, from nursery rhymes to show tunes), and playing a game of a peer's choosing (they take it in turns to choose the game, and play nicely)
and all that is just an overview! her day is as varied (and possibly more so given the utter flexibility of having your own curriculum and tutor) as dd2's (in Yr2). each target on her comprehensive IEP can be taught in a variety of ways and situations, and is done so. each target is flexible across the day - so while working on her motor skills via yoga, she is also working on her listening skills and imitation skills. while working on her conversation via mind maps, she is also reading, matching, writing etc (just like any child at any school).
the absolute last thing she is doing is sitting at a desk all day long doing trials.
