Y1 TA here. So far this year we've had:
2x trips to local sciency place within walking distance - only out of school for a couple of hours total each time, inc walking distance.
A walk around the local area for RE.
Trip to local library for storytime - only gone for 50 minutes total.
Whole day out of school at the theatre where we did the Y1 production. Rehersal in morning, performance in afternoon. Walked there, any children not collected after the performance from the theatre were taken back to school in the minibus.
Big whole day trip to the zoo - 1h coach ride each way. We're in a low-income area, but all but 3 families paid the full £15 cost.
Off the top of my head, we still have 3 trips left - 2 walking distance, probably half-days, and the 3rd which will need a coach, maybe 20 mins drive away, also probably only a half day.
So I make that 9, not including anything we don't send letters home for - so end of term services at a church 25mins walk away, going to the Juniors for a cinema experience, going to the church right next door for RE (at least once a 1/2 term), and going to the "secret garden" between the Infants and the Juniors.
So that seems a lot compared to previous posters...
