Before you begin
Build and connect the representations and methods in measurement and shapes.
Learning goals
- Represent and calculate monetary amounts
- Measure and compare length, mass and liquid volume
- Convert compatible measurement units
- Read clocks and calculate durations
- Distinguish area, perimeter and volume and their units
- Calculate the length of a plane figure's complete boundary
- Calculate the area of a plane figure
- Compare an angle with a right angle
- Classify shapes by their properties
- 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 time in seconds
- finding the starting time, finishing time or duration given the other two quantities
- 24-hour clock
- concepts of area and perimeter of a plane figure
- 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
- perpendicular and parallel lines
- drawing perpendicular and parallel lines

About lesson progress
Lesson marks record what you have studied. Checks show understanding separately. Guest marks come from this device.
- Money totals and changeAlign dollars with dollars and cents with cents, and choose the operation from the money story.
- Convert compound measurementsKeep the measured quantity fixed while changing between compound and smaller units.
- Seconds and measured durationsConvert minutes and seconds and measure short durations with a stopwatch.
- Area and perimeterDistinguish covering a surface from tracing its boundary, then calculate both for rectangles and squares.
- Turns, parallel lines and square cornersCompare angles with a right angle and draw perpendicular or parallel lines using their defining properties.
- The 24-hour clock and durationsFind start times, finish times and durations while respecting sixty minutes per hour.
