GM1-1: Order and compare objects or events by length, area, volume and capacity, weight (mass), turn (angle), temperature, and time by direct comparison and/or counting whole numbers of units.

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Elaboration on this Achievement Objective

This means students will go through a stage of using direct comparison to establish the relative length, area, volume, weight and temperature of objects. This means that the objects are brought together physically. Through experiences using direct comparison techniques students will come to appreciate the need for units of measure so that objects can be compared without bringing them together. Units have the attribute being measured, have to be the same size and are combined and counted. For example handspans can be used to compare the length of a table and the height of a door. Students are expected to apply their number strategies to count these units. Students are expected to explore turns (angles) through bodily movement and time through comparing durations of events.
