Union Jack

I didn't think this challenge for child's Play would be so difficult. The challenge is the game of Jacks. I remember being really bad at it as a kid and being wowed by my Mum's abilities.
I racked my brains to think of a way of using the game in a LO but couldn't think of one so instead I just took the name Jack for the title of my LO and made this one about Nancy drawing on a plastic Union Jack sheet at the Olympics
