I've prepared a few posts about school visits entitled Advice From the Trenches - in four parts.
I hope to post the first one on Wednesday.
Part 2 got published prematurely (by mistake) - so I deleted it and will repost later in the week - after Part 1.
If you use a blog reader, it may have picked up that Part 2 post - but the original is no longer available for viewing until I repost it later in the week.
Sorry about that.
