This is Day One (window one) of my advent calendar of gifts for writers. I thought I'd start with something that's not only fun but could also be useful for inspiring writerly youngsters - Magic and Fairy Tale Dice.
Each die provides a different element of a story - a character, a prop, or a place. The Magic and Fairy Tale Dice would be perfect for a family game but equally could be a fun writing prompt too.
I found these in the Alzheimer's Society's online store priced £9.95 but you can also buy this dice set on Amazon, eBay and several book and toy related stores.
