- Year 9
Designing a green space
I can design a green space whilst considering the community.
Lesson details
Key learning points
- When designing, restrictions are likely to exist
- A scale model/map is helpful to visualise the end result
Keywords
Urban - Urban is a word to describe a town or city, or certain properties of towns and cities.
Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Truncate - Simplifying a number by 'cutting off' one or more of the digits and replacing them with zeros if necessary to preserve place value.
Common misconception
When performing divisions to calculate the maximum number of plants that fit into a space, pupils may round decimal answers up to the nearest integer (e.g. round 4.5 plants up to 5 plants).
The context would suggest that it may be more appropriate to truncate decimal answers to an integer rather than rounding them up to the nearest integer (e.g. there is not enough space available to fit the 5th plant).
