Maths Unit Plan – Measurement
Level 4
New Zealand Curriculum Links
In a range of meaningful contexts, students will be engaged in thinking mathematically and statistically. They will
solve problems and model situations that require them to:

Use appropriate scales, devices, and metric units for length, area, volume and capacity, weight (mass),
temperature, angle, and time.

Convert between metric units, using whole numbers and commonly used decimals.

Use side or edge lengths to find the perimeters and areas of rectangles, parallelograms, and triangles and the
volumes of cuboids.

Interpret and use scales, timetables, and charts.
National Standard link: In contexts that require them to solve problems or model situations, they will be able to:
End Year 7

make simple conversions between units, using
whole numbers

use side or edge lengths to find the perimeters and
areas of rectangles and parallelograms and the
volumes of cuboids, given whole-number

Learning Outcomes

use a formula to calculate the volume of cuboids by measuring the length of each of the 3 dimensions

recognise that objects have many measure attributes

identify and accurately measure attributes of common objects

estimate the volume/mass of one marshmallow using appropriate standard units.

design an investigation to find the average volume/mass of one marshmallow

carry out an investigation to find the average volume/mass of one marshmallow
