For many young children it seems obvious that longer objects are heavier than shorter objects. This assumption is put to the test as the class investigates the relationship between length and weight in a whole-group activity. Using a balance, the teacher compares objects of varying length and weight to demonstrate for young learners that these two attributes are actually independent of one another. A fun math activity that raises awareness in young mathematicians that objects can be measured in a variety of different ways.
