# Learning By Topic KS2: The Environment and Mathematics

Over a period of two weeks, look up the air pollution forecast on the Department for Environment Food and Rural Affairs website: https://uk-air.defra.gov.uk/ and keep a record of pollution levels. Now record the data on a bar chart.

Extension/Upper KS2: From the above data can you find the mean, median, range and mode?

Create a number code for the alphabet (e.g. a =1 b=2 be a bit more adventurous than this example) write your theme words using this code – can anyone crack your codes?!

Now ask an adult to write some addition, subtraction, multiplication and division sums in this code. Can you decode these and then solve them?

Find the perimeter and area of your garden.

Measure different angles around your garden or local environment. Maybe take some photos and then sort them into a table with the heading, acute angles, right angles, obtuse angles, straight angles and reflex angles. Top Tip: You can either print photos for this activity or construct your table on the computer and cut and paste the photos in.

Think about professions that involve people protecting and caring for the environment (e.g. forest rangers, marine biologist, vets). In what ways do they use maths in their jobs?

Keep a record of your household waste over a week – what percentage of household waste do you recycle?

What percentage of the Amazon Rainforest has been affected by deforestation?
