Lesson details

Key learning points

  1. When designing, restrictions are likely to exist
  2. 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).

Task B could be extended by asking pupils to consider different ways to arrange the plants within the planting box. E.g. could more plants fit into available space if they were staggered, rather than arranged in rows and columns? This could be explored using dynamic geometry software.
