Identify a part of a whole group
Lesson details
Learning outcome
I can identify a part of a whole group.
Key learning points
- If some of the objects in the group are missing, it is not the whole group it is part of the group.
- This is a whole group of --- because I have all of them and none are missing.
- This is not the whole group of ---because I do not have all of them and some of them are missing.
- There are ---- in the whole group and __ in this part of the group.
Keywords
Whole - All of something. Complete.
Part - A piece or section of a whole.
Whole group - A group of objects that form a whole set.
Common misconception
Children may find it hard to understand that a group of objects can represent a whole.
Use the correct language to emphasise the 'whole group of ..........' and explore what happens when a part is missing.
Teacher tip
Use practical examples of whole sets of objects in clearly sectioned containers, e.g. boxes of eggs and boxes of sweets as well as sets in an unsectioned container, e.g. a bag of toys and sets not in a container, e.g. a group of toys.
