Student challenge

Part 1: What is Green Space?

Help your students learn what the term 'green space' means by conducting a quick Think, Pair, Share (explained below).

Students will have ten seconds to silently think of their own definition of green space. After ten seconds, each student should pair up with another student and discuss possible definitions. Students should explore what the concept might mean and decide on the best answer. Select a few pairs of students to share their answer with the class. Help them to realise that green space is undeveloped land that is near to residential or industrial land. It should be maintained for purposes of conservation and recreational enjoyment.

Student Worksheet

Your job is to think about the most effective way to estimate and compare areas of 'green space'!

Part 1: What is Green Space?

Firstly, what is green space? Let's do a Think, Pair, Share (see explanation below).

You have ten seconds to silently think of your own definition of green space. After ten seconds pair up with another student and discuss both of your definitions and decide on the best answer. You will then share your answer with the class.

Part 2: Google Maps

Questions: Use Google maps to find an arial map of a local area. Answer the following questions:

1. Define the school's neighbourhood.

2. What is the main land use in the neighbourhood? What percentage or fraction does it take up?
