As a teacher in the UK you should be aware that October is Black History Month. This serves as a reminder that Black history is a vital part of British history, often overlooked in traditional narratives as it began in the Roman period, long before any concept of the United Kingdom or any of its member nations existed.
It was first observed in the UK in 1987, inspired by the American initiative but adapted to focus on the unique experiences and history of Black people in Britain.

To support you in teaching about this History the BBC has produced a wealth of resources from KS1-KS4. You can use these in your class, your form time or any assemblies you do. In it you will find videos and lesson activities.
If you want some more practicallesson activities to explore this history then Twinkle has many available for its members and even some of them are free.
