Thank you for your suggestions! I decided to put together a set of my own, great fun! It currently consists of:
A teacher registration book
A teaching clock
Lots of reward stickers
Some laminated math posters with numbers/shapes
A handful of ruled exercise books
A handful of workbooks spelling/math/tell the time
A handful of Level 1 reading books (our first language is not English but dd currently goes to an American school, so good practice)
Still not decided whether I will go with a white board or self-adhesive black board. Will also get board eraser and chalk/white board markers.
This is turning out to be quite an expensive present, but very successful I expect!
And the questions is whether I have missed something crucial...
