Lesson details
Key learning points
- Recognise amounts that have been rearranged.
- Generalise that if nothing has been added or taken away, then the amount is the same.
Keywords
Same - Way in which two or more things we are comparing are like each other.
None - None means the same as nothing or not having changed something.
Some - Some means a number of things.
Common misconception
If using slides, not recognising objects have been rearranged and counting all again.
Gather objects to manipulate (either under a visualiser with the whole class, or in front of a small group) so that children can clearly see that none have been added or taken away.
