Measures in the primary curriculum

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.
