The same hunt-and-circle idea as the first grade word hunt, with one word added to the instruction that changes everything: circle every word that names a body part, inside or outside. The sixteen to find are skin, brain, rib, shin, belly, heart, gums, eyelash, jaw, forehead, earlobe, knuckle, kneecap, throat, thigh and lungs, scattered through sixty-two words. A line at the bottom asks for the total.
Inside or outside is what lifts this to second grade. Brain, heart, lungs and ribs are parts nobody can point to on themselves, so a child has to hold a definition in mind rather than picture a spot on their body. The outside words are harder here too, since earlobe, knuckle, kneecap and forehead are all compounds a second grader can read but has rarely been asked to think about. Asking for a count at the end means the sheet checks itself: sixteen is the number, and anything less sends them back through the box.
