Lesson Plan

5 mins Starter — Perceptions Check

Anonymous poll: rank the top 3 reasons you think young people carry knives. Reveal results and compare to actual research data.

10 mins Statistics Deep Dive

Pupils analyse real statistics. Guided questions: Who is most likely to be a victim? What does this tell us about the 'protection' argument?

12 mins The Legal Consequences

Walk through the Offensive Weapons Act 2019. Case studies (anonymised) showing how ordinary young people's futures were changed by one decision.

12 mins Pressure Mapping

Small groups map the social pressures that lead to carrying: fear, peer group, social media, gang affiliation. Discuss which pressures can be resisted and how.

10 mins Refusal Strategies

Role-play: how do you decline being given a knife, refuse to 'hold it for a mate', or exit a situation where weapons are present without losing face?

6 mins Plenary

Exit ticket: three things I now know, one thing I would do differently, one thing I'm still unsure about.

5 mins Signposting

Distribute support information. Emphasise anonymous reporting options.

⚠️ Safeguarding Considerations

At KS4, pupils may already be involved in situations where weapons are present — respond without judgment
This session may prompt disclosures about carrying, being threatened, or witnessing violence
Pupils who are being exploited via county lines may be under pressure to carry — be alert to this
If any pupil expresses current fear for their safety, this takes priority over the lesson
Know your school's DSL and threshold for referral
Have Crimestoppers and Fearless information visible throughout the session

If a pupil makes a disclosure during this session, follow your school's safeguarding procedures and refer to your DSL immediately.

Key Messages

One bad decision can permanently alter the trajectory of your life
Carrying a knife statistically increases your risk of being stabbed
The law does not recognise self-defence as a reason to carry a bladed weapon
A criminal record affects university applications, employment, and international travel
Peer pressure to carry a knife is a form of exploitation — you have the right to refuse
Anonymous reporting saves lives — yours and others'
