This is a fantastic game, and can be played without much space (a rug in a living room will do).
And it’s not really a race - kids take turns picking who shouts something out and teaching the movement, and that kid leads the way.
Kids line up on one side of the rug - shout something out, and then make that motion as they hurry across the rug and back (one at a time).
Examples of things shouted are:
*Froggy (hop across)
*Crabby (move sideways with pinch pinch)
*Cars The Movie, it’s your birthday (silly)
*Ballerina Moves
*Big hops
