Longest - The object in a set that is longer than all the others.
Shortest - The object in a set that is shorter than all the others.
Tallest - The object in a set that is taller than all the others.
Common misconception
When comparing objects, children may think that one is longer or taller because they have not aligned them to start at the same point.
Encourage children to place objects on a flat surface such as a table when comparing height, or against a wall when comparing length to make sure that they have the same start point.
