Constructing a whole
I can construct a whole when given one part and the fraction that it represents.
Lesson details
Key learning points
- If you know a part and the fraction it represents, you can construct the whole.
- If one-__________ is a part, then the whole is __________ times as much.
- Take __________ parts and put them together to make one whole.
Keywords
Construct - Construct means to make or build something. In the context of this lesson, it means to make or build a whole from equal parts.
Common misconception
Children may struggle to construct the whole from a given part. They may misunderstand the total number of parts needed as this includes the original part.
Emphasise the denominator as the number of equal parts and ensure the learner sees the part they have as one of ___ equal parts. Take time to construct and deconstruct wholes from and into equal parts so learners know what to include in the count.
Practical experience of creating wholes from equal parts is vital here. Consider what real-life and practical experiences you could provide pupils such as using cubes or counters or shapes divided into equal parts. Handling parts and wholes will enhance understanding of key learning.
