Childhood Milestones

Overview

In this second session of the unit, students explore physical development from birth to the start of pre-adolescence. They identify key physical milestones and analyse factors that can influence development.

Learning intentions

• WALT identify key physical milestones from birth to pre-adolescence.
• WALT analyse factors that may affect physical development over time.
• WALT use evidence from case studies to explain development patterns.
• WALT create and use a physical development timeline to demonstrate understanding.

Success criteria

• I can describe major physical milestones for different age stages (birth to pre-adolescence).
• I can explain at least three factors that can influence physical development.
• I can use information from a case study to support my timeline choices.
• I can answer recall questions accurately and correct misconceptions when prompted.

Curriculum links

• PSHE education: relationships and health (how bodies grow and change; physical health and wellbeing).
• Citizenship and personal wellbeing themes: recognising how individual circumstances can affect development.
• Health education: understanding normal development and the importance of support for health needs.
• Skills for life: group discussion, using evidence, and communicating explanations clearly.

Lesson structure (60 minutes)

1. 5 min – Starter: recall quick quiz Students complete a short, teacher-led quiz (5–8 questions) on physical milestones from birth to early childhood (e.g., rolling, sitting, walking) using whiteboards or mini-answers. Teacher uses misconceptions as prompts for immediate discussion.

2. 10 min – Video engagement: “watch and note” Students watch a short video clip (teacher-selected) showing growth and physical development stages. They record two milestones they already knew and one milestone that surprised them, using sentence stems such as “I noticed that…” and “One milestone is…”

3. 12 min – Teach: milestones overview (birth to pre-adolescence) Teacher provides a clear chronological outline of expected physical development phases, emphasising that there is a normal range and individual variation. Students add one new detail to their notes for each phase, linking to what changes (mobility, growth rates, puberty onset signals later).

4. 13 min – Case study analysis in groups In groups of 4–5, students receive a short case study card (e.g., early nutrition support, chronic illness risk, access to healthcare, safe environment, disability, or family circumstances). Students answer:

• What physical development milestones are happening/what may be delayed?
• What factors might be influencing physical development?
• What support could help? Teacher circulates, prompts evidence use, and checks understanding.

5. 10 min – Group transformation: “from case to timeline” Each group turns their case study insights into 3–4 timeline “events” (milestone + likely influence + support). Groups prepare a brief presentation pitch (30–45 seconds) to present their timeline events to the class.

6. 7 min – Whole-class consolidation Teacher draws out patterns: “normal range,” “influencing factors,” and “support matters.” Students correct any inaccurate milestone statements using teacher feedback and peer input.

7. 3 min – Independent learning task instructions Students are set the independent task: create a physical development timeline for one child scenario (provided separately) from birth to pre-adolescence, including milestone markers and 3 influencing factors with brief justification.

Resources

• Teacher-made recall quiz (printed or on slides) with age-appropriate physical milestone questions.
• Short child development video clips (safe, school-appropriate, non-graphic).
• Case study cards with clear, factual prompts (1 per group).
• Timeline template (A4 or digital) with space for milestones, dates/age ranges, and factors.
• Whiteboards or mini-whiteboard pens (or paper slips) for quick quiz responses.
• Marking guide or “success criteria” reminder sheet for peer discussion.
• Sentence stems for scaffolding discussion (e.g., “A factor that could influence is…”).
• Dyslexia-friendly reading pack: audio option, larger font version, and simplified text summary of milestones.

Assessment

• Formative: observe quiz answers and group discussions for misconceptions about milestone sequencing or expectations.
• Formative: collect group timeline events and check that each includes a milestone plus an influencing factor and support link.
• Summative (for next lesson): independent timeline submission will be assessed against success criteria.

Differentiation

• Support for learners: provide partially completed timeline templates, sentence stems, and a simplified case study reading option.
• Support for SEN/EAL: allow bilingual support where appropriate, and provide visuals (icon-based milestone cues) and a glossary of key terms (e.g., milestone, growth rate, development).
• Challenge for advanced learners: require additional accuracy tasks such as identifying “normal variation” and explaining why outcomes differ even when timelines overlap.
• Dyslexia-friendly options: use larger font handouts, short paragraph case studies, allow audio reading of cards/videos, and permit oral answers before written output.

Extension (optional)

If time allows, advanced students add a “support and impact” column to their timeline (e.g., how nutrition, safeguarding, healthcare access, and safe physical activity can affect outcomes) and justify with evidence from the case study.
