New Zealand Curriculum: Level 3 to early Level 4
Learning Progression Frameworks: Measurement sense, Signpost 5 to Signpost 7
These activities are intended for students who understand how to use units of measure to find length and areas of rectangles. They should understand the following:
- Units relate to the attribute being measured (for example, area is measured with iterations of area).
- Identical units need to be used when measuring.
- Units should be tiled (or iterated) with no gaps or overlaps to create a measure.
- Units can be equally partitioned into smaller units when greater accuracy is needed.
Students should also know how to use a measurement scale, such as a ruler or tape measure. They should be familiar with the common metric units of length, metres, centimetres, and possibly millimetres, though they may not be able to convert measures (e.g., 45cm = 450mm). Students should have a partial or full grasp of their basic multiplication facts and the division equivalents.
The following diagnostic questions indicate students’ understanding of, and ability to find the volumes and surface area of cuboids (rectangular prisms). Allow access to pencils, paper and to a calculator if needed (show diagnostic questions).
