This post by Forvie National Nature Reserve (15 May 2022) shares the story of how the annual census of Forvie’s Black-headed Gull colony is carried out. Check out ‘ 25 kilograms of flour and 6,000 eggs’. It also shares a lot of numbers! This provides a great opportunity to introduce natural and real data into any classroom math’s work. Also the opportunity to discuss what common and abundant might mean in the real world.
