Common misconception

Sometimes parts can be deceptive and look equal but are in fact unequal. For example, the rhombus that has been split into parts with lines that are equally distributed.

Explore this further by presenting several examples like this if needed. You could ask the children to try and think of some examples where the parts look equal but are in fact unequal. Getting the children thinking of this will boost understanding.
