As a class make a list of objects in the classroom that could be used to measure length. [you may even think of parts of your body that could be used]
Get into pairs [depending on student numbers] With your pair choose 4 objects from the class list to measure.
Choose 4 things in the classroom you could measure using your 4 measuring objects.
Measurements you could measure - length / height / with / depth.
Record these on the recording sheet. This can be found in your math folder on your drive.
