It is suitable for:
primary PSHE lessons
relationships education
pastoral care, circle time or form time

introductory puberty awareness work
Suitability should be based on more than age alone. Teachers should consider the lesson focus, pupil 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 changes and growth Use when pupils are learning early, factual language about how bodies change over time.
Building on relationships education Use when reinforcing respectful, age-appropriate discussion of body changes as part of a wider unit.
Supporting a health and wellbeing topic Use when body changes and growth form part of a broader health or PSHE topic.
Preparing for transition Use when pupils are moving towards later changes and may have early questions about growing up.
Reinforcing respectful language Use when pupils need practice using factual, respectful language about bodies and growth.
Creating a structured PSHE discussion Use when you want a calm, teacher-led discussion about growth and body changes.
The lesson can be used proactively with the whole class. It does not need to follow a specific incident.
Why this lesson matters
Pupils benefit from calm, factual language for understanding how bodies grow and change, well before questions or changes become confusing or worrying. Teaching about body changes early helps normalise growth as a natural part of life. It gives pupils confidence to ask questions, recognise that everyone grows at their own pace, and understand that some parts of the body are private. This lesson supports a classroom culture where pupils feel comfortable discussing growth and change respectfully, and where they know a trusted adult is available if they have questions or feel unsure.

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 pupils not to name classmates or share other people's personal experiences
Frame the discussion around general growth and change, not individual pupils' bodies
Make clear that everyone grows and changes at their own pace
Identify trusted adults pupils can speak to at school
Be prepared to follow your school's safeguarding procedures and speak with the designated safeguarding lead if a pupil discloses harm or says they feel unsafe.
During delivery
Use simple, factual language such as growing taller and bodies change over time
Keep the discussion body-respectful and free from judgement about appearance or pace of change
Give pupils time to ask general questions rather than personal ones
Allow pupils to respond through discussion or written reflection depending on confidence and maturity
Supporting safe discussion
Reinforce that questions about growing up are normal and welcome
Remind pupils that some body changes are private
Follow your school's safeguarding procedures if concerns arise
Adaptation options
Use partner or written reflection for quieter groups
Spend more time identifying trusted adults if pupils need support with help pathways
Adjust pacing depending on pupils' existing understanding of growth and change
Keep the tone calm and matter of fact throughout, avoiding any suggestion that there is one normal pathway or timeline for growth.
