Game: Sit your child on your knees. As the song calls for the men to go 'up', raise your knees until your child is up. Lower your knees to the floor when the men are 'down' and leave your knees mid-way up for 'halfway up'.

Oh, the grand old Duke of York he had ten thousand men
He marched them up to the top of the hill
and he marched them down again.
When they were up, they were up
and when they were down, they were down
and when they were only halfway up
they were neither up nor down.
