This 1 lesson program + facilitators guide is great for any classroom going through a smelly stage. Geared more towards boys, it uses great resources, humour and pictures to guide the class through the hidden rules of hygiene.
There are questions/topics the facilitator can use to promote discussion during the lesson. Following the lesson, there is a Locker Room Hygiene Quiz the kids can take to test their knowledge. It's a fun way to go about a sensitive and awkward issue!
