Who this lesson is for?
This lesson is designed for younger primary students in Years 1 and 2 who are beginning to learn about body growth and change in simple, factual terms.
It is suitable for:
primary wellbeing lessons
Health or PDHPE teaching
pastoral care, circle time or advisory sessions
early puberty education or body awareness learning
respectful relationships and protective behaviours work
Suitability should be based on more than age alone. Teachers should consider the lesson focus, student maturity, cohort needs, classroom culture, existing discussion norms and available support pathways.
Best used when
Use this lesson when students need clear, practical language for recognising unkind behaviour and knowing what to do next.
Introducing body growth and change Use when students are learning early language for body changes and growth for the first time.
Building a Health or PDHPE unit Use when body changes forms part of a broader Health or PDHPE sequence on growth and development.
Reinforcing respect and privacy Use when reinforcing respectful language and personal boundaries around bodies.
Supporting protective behaviours learning Use alongside broader protective behaviours or respectful relationships teaching.
Preparing for transition Use when students are moving into new stages of schooling and may have early questions about growing up.
Creating a structured wellbeing discussion Use when you want a calm, teacher-led discussion about body changes and growth.
The lesson can be used proactively with the whole class. It does not need to follow a specific incident.
Why this lesson matters
Young students often notice body changes in themselves and their peers well before they have the language to talk about them calmly and factually. Introducing body growth and change early gives students a shared, respectful vocabulary and helps normalise the idea that growth happens differently for everyone. It also opens the door for students to ask questions and know who they can speak to if something feels confusing or unclear. This lesson supports a classroom culture where body changes are discussed factually and respectfully, without shame or comparison, and where students understand that trusted adults are available to help with questions.

Teaching notes & Delivery Considerations
This lesson includes content about unkind behaviour, exclusion and asking adults for help. It should be taught with calm, clear discussion norms.

Before teaching
Remind students that bodies grow and change differently for everyone, and there is no single normal pathway
Frame discussion around general growth and change, not personal appearance or comparison
Identify trusted adults students can speak to if they have questions about their own body
Be prepared to follow your school's child safety, wellbeing or child protection procedures if a student discloses harm or says they feel unsafe.

During delivery
Use simple, factual examples such as growing taller, losing teeth or gaining new skills
Avoid singling out individual students when discussing body changes
Keep language body-respectful and avoid comments about appearance
Allow students to ask questions and respond calmly and factually

Supporting safe discussion
Remind students not to name classmates or share personal stories about others
Reinforce that privacy and personal boundaries matter when talking about bodies
Explain that questions about their own body can be shared with a trusted adult

Adaptation options
Use simple visuals or discussion prompts for younger or less verbal groups
Spend more time on trusted adults if students need support identifying who to ask
Adjust pacing depending on prior learning and classroom readiness
