Key Stage 3 - Maths in the environment activity tour

In this session, secondary school students strengthen their basic numeracy skills while enjoying the outdoors.  Estimation, measurement and simple calculation skills are reinforced as students use different techniques to find the height, width and age of trees.

Students use many methods to measure and estimate the size and age of trees.


Students practice basic numeracy skills while enjoying the outdoors. They practice various estimation and measurement techniques and calculate the height, age, and circumference of trees, amongst other parameters.

  • Length: 45 minutes.
  • Group size: 15 students.
  • Minimum supervision required: 1 adult per 10 students.

Learning outcomes

School visits at Kew Gardens support and enhance the curriculum offered in schools. We aim to give students opportunities that are difficult or impossible to create in the school environment.

The learning outcomes shown apply to the curriculum as it is at this time. This session offers students the opportunity to learn to:

  • recognise when exact measurements or calculations are appropriate and when estimation is appropriate in the context of a mathematical problem
  • demonstrate estimation techniques in measurement and calculation
  • carry out basic mathematical calculations (e.g. addition, subtraction, multiplication and division) in solving environmental problems
  • recognise and plot relationships between two variables
