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
Name two major muscle groups.
For example, the quadriceps (front of the thigh) and the biceps (front of the upper arm).
QUESTION 2
What does the core do?
It stabilizes the trunk and helps you bend, twist, and keep your balance.
QUESTION 3
Why train all the major muscle groups?
To build balanced strength, support good movement, and lower the chance of injury.

Create: a full-body circuit.

Have students pick one exercise for each major muscle group, order them into a balanced circuit, and label the muscle each move works. A printable muscle-groups worksheet is in the PE & Health library.
