Lesson details
Key learning points
- Ten ones are equal to one ten.
- One ten is equal to ten ones.
- Ten pennies are equal to one ten pence.
Common misconception
Children may rely on counting in ones rather than recognise a group of ten.
Encourage children to recognise groups of ten in a variety of contexts. They may need to check one e.g. a bundle of 10 straws but then should be encouraged to use comparative size to know other groups are of equal size.
Keywords
Ten - A group of ten objects.
Ones - Individual objects, grouped in ones.
Equal to - Exactly the same amount or value.
Reinforce the groups of ten by using the stem sentences: ten ones are equal to one ten, one ten is equal to ten ones, we have one group of ten, we have one ten.
