Music player, music (any type), paper, crayons
Put on some music for your little one. It can be classical, jazzy, kids or adult music. Give him a paper and crayon and have him draw the music he hears. Does it make him want to make slow, lazy loops or fast and frantic dots? Does it make him feel like using a blue, red or yellow crayon? Do it alongside your child and compare whether your drawings are the same or different!
