Worked brilliantly with my year 6 class as they worked in mixed ability groups.
Presentation showing children different climates and where they occur on the world map (discussing distance from equator).
Activity where children label animals and plants with how they have adapted (eg. Polar Bear: thick fur and fat to keep warm, white fur to camouflage).
End of presentation gives children prompts to respond to in books to ensure deeper understanding.
