Lesson details

Key learning points

Missing dimensions can be deduced from other known dimensions.
Where the volume is known, multiplication or division can be used to find an unknown dimension.
Unknown dimension problems can be applied to different contexts.

Keywords

Deduce - If we use existing facts and logic to help find new facts, we can say that we have deduced the new fact.
Dimension - A dimension is the measurement of an edge in one direction. For example: length, width or height of a 3D shape are dimensions.

Common misconception

Pupils cannot visualise how to calculate the unknown dimensions on the compound shape.

Spend time encouraging pupils to note down 'what they know' onto each shape. Allowing pupils to manipulate the shape with concrete apparatus and to run their finger along the edges of the shape will help visualise what is known and unknown.

When finding the value of an unknown dimension, recording the unknown as a part of a multiplication equation as a missing factor will help pupils to draw upon their understanding of multiplicative structures to identify division as the inverse of multiplication.
