Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
What is a joint?
A place where two bones meet, which is where the body bends and moves since bones themselves cannot bend.
QUESTION 2
Why does cartilage matter in a joint?
Smooth cartilage cushions the bone ends and lets them glide, so the bones do not grind against each other.
QUESTION 3
Name one kind of joint and a place you have it.
A hinge joint (elbow or knee) or a ball-and-socket joint (shoulder or hip).

Create: my joint map.

Have students trace a body outline, mark five joints, and label what each one lets them do, so they can see how the body is built to move. A printable joints worksheet is in the PE & Health library.
