Lesson Details

Key learning points

Lengths can be compared using longer, taller and shorter.
A length can be the longest tallest or the shortest of a set of measurements.
Height is a type of length.
Lengths can be equal to one another.
Objects can be ordered by height and length.

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.
