Measuring Length with Informal Units
In this worksheet, students measure things using their body parts, and compare those measurements to others in the class to experience the limitations of informal units.
It is a part of a larger unit designed to transition students from informal units to measuring, ordering and comparing items in formal units of length.

Learning goals
- We are learning to identify which metric units are used to measure items and to make estimates using known units.
- We are learning to measure and compare objects and events using length, mass and capacity and use instruments with labelled markings, e.g. measuring tape, ruler.
- We are learning to measure, order and compare objects using standard metric units of length, mass and capacity.
