About this topic

Before you begin

Calculate money totals and change, convert measurements, work with time, and distinguish area, perimeter and angle relationships.

Learning goals
  • Represent and calculate monetary amounts
  • Measure and compare length, mass and liquid volume
  • Convert compatible measurement units
  • Read clocks and calculate durations
  • Measure covered area in equal square units
  • Construct area and perimeter contrasts with plane figures
  • Calculate the length of a plane figure's complete boundary
  • Calculate the area of a plane figure
  • Compare an angle with a right angle
  • Compare two angles by their openings, not their arm lengths
  • Identify every pair of parallel or perpendicular sides in a figure
  • Draw a distinct line parallel to a given line
  • Draw a line perpendicular to a given line
  • Convert between 12-hour and 24-hour clock notation
  • Find a duration from starting and finishing clock times
  • Find a starting or finishing clock time from a duration
Syllabus statements covered
  • Adding and subtracting money in decimal notation
  • Measuring
  • Length in kilometres (km)
  • Volume of liquid in millilitres (ml)
  • Measuring length/mass/volume (of liquid) in compound units
  • Converting a measurement in compound units to the smaller unit, and vice versa
  • Kilometres and metres
  • Metres and centimetres
  • Kilograms and grams
  • Litres and millilitres (numbers involved should be within easy manipulation)

  • Measuring area in square units, cm² and m², excluding conversion between cm² and m²
  • Perimeter of
  • Rectilinear figure
  • Rectangle
  • Square
  • Area of rectangle/square
  • Concepts of angle
  • Right angles, angles greater than/smaller than a right angle
