jan and katrina like to play the windmill game. they get bram and hilda and kassie and karl to play with them.

this is the way they play the game. each one chooses a partner. they stand back to back. they stretch out their arms. they wave their arms up and down. when one arm goes up the other arm goes down. they look like a windmill whirling around.

they sing:

windmill, windmill, whirl around

with a whirring, creaking sound,

up and down,

away we go,

windmills go both fast and slow.

it takes two children to make a windmill in this windmill game. if jan and hilda and kassie and karl and bram and katrina all play, how many windmills do they make?
