Lesson details
Learning outcome
I can explain that one ten is equivalent to ten ones.
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.
Keywords
Ten - A group of ten objects.
Ones - Individual objects, grouped in ones.
Equal to - Exactly the same amount or value.
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.
Teacher tip
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.
