Thanks for the replies. It did have a list of suggested items, but I think I overcomplicated it looking at the stuff, thinking what would a 5-9 year old boy or girl really want. I think that is actually a very big age range with lots of development in between and that's what I found tricky. Practically a toddler at one end; nearly a teenager at the other.
The P*undland idea was good; geometry sets and ...recorders!
Discussion about the literature accompanied or otherwise was vvv interesting. Ours is Samaritan's Purse. It states: "We always give shoeboxes to children based on need, regardless of their background or religious beliefs. It's an unconditional gift of love. Where appropriate, with each shoebox, our church partners may offer a little booklet of Bible stories. They may also invite children receiving shoeboxes to join a discipleship course called The Greatest Journey. This is a 'no strings attached' programme and participation is with the consent of their parent or guardian."
