Interview someone who has born before 1990 (i.e could be your grandparents, mum or dad, auntie, etc) and ask them questions about a game they enjoyed playing when they were young. (i.e. marbles, skipping, knuckles, hopscotch, etc). Challenge 1: find a photo of the game and label it to describe it. Challenge 2: find a video showing someone playing this game. OR if possible, record yourself playing this game.
