This one-page 4th grade skeletal system check has an answer key on page 2 and works as a quick quiz. Students label five bones from a word bank (skull, ribs, spine, pelvis, femur), name two jobs of the skeleton and match the elbow and shoulder to hinge or ball-and-socket joints. Two boxed questions ask what the ribs protect and how many bones an adult has. It supports NGSS 4-LS1-1.
