A mathematics investigation involving length, embedded in a real-world context.
This open-ended mathematics investigation has been designed to deepen students’ understanding of length.
In this investigation, the school principal needs to find helpers to give a signal to be quiet during assemblies. The assemblies take place in a large space so he needs people with long fingers so that everyone can actually see the signal!
This teaching resource includes:
- teacher notes, detailing a range of important information about the investigation
- a detailed description of the investigation for students, including step-by-step instructions
- collecting and recording data worksheet
- reflection questions.

Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it wi...
Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/sho...
