The sign for homework is a "compound" sign made from a combination of the signs "HOME" and "WORK."
Normally the sign HOME makes a double touch to the cheek (first near the mouth, then higher up toward the ear).
Normally the sign WORK makes a double movement (whacking the non-dominant fist with the dominant fist twice).
But for the sign "HOMEWORK" you just touch the cheek just once and whack your non-dominant hand just once.
