**Area - fifth and sixth class**

Content for fifth class

*The child should be enabled to*

- Discover that the area of a rectangle is length by breadth.

*Determine by repeated experiments using rectangles with sides measured in whole centimetres and square units of one square centimetre* - Estimate and measure the area of regular and irregular 2-D shapes?

*Measure a wide variety of regular and irregular shapes using square units of one square centimetre and one square metre.* - Calculate area using square centimetres and square metres?

*Choose appropriate measuring units: e.g. square centimetres (smaller objects) or*

square metres (large objects or rooms). - Compare visually square metres and square centimetres.

Content for sixth class

*The child should be enabled to*

- Recognise that the length of the perimeter of a rectangular shape does not determine the area of the shape?

*Construct rectangles of constant perimeter with varying areas.* - Calculate the area of regular and irregular 2-D shapes?

*Estimate and calculate area of shapes, and check by measuring with square centimetre unit’s circles: calculate by counting squares only?* - Measure the surface area of specified 3-D shapes.

*Measure 3-D surfaces by measuring individual 2-D faces or by extending into nets.* - Calculate area using acres and hectares e.g.
*fields, large playgrounds, car parks?* - Identify the relationship between square metres and square centimetres?

*Explore and compare areas of one, four, twenty-five and one hundred square centimetres to establish relationships?* - Find the area of a room from a scale plan?

*Measure and calculate area of rectangular shapes by partitioning into rectangles and combining individual areas?*

Extend to finding area of room plans (rectangular).

Extend to using scale to find area of rooms from plans.
