Lesson details
Key learning points
- Ten ones are equivalent to one ten.
- When counting larger groups, it is more efficient to group objects into tens, then count the tens and extra ones.
- We can work out how many there are by counting in ones, or by counting the groups of ten and extra ones.
Keywords
Digit - A single symbol used to make a numeral.
Common misconception
Children may only think of 'ones' in terms of the extra ones after the tens have been grouped, so may fail to see 45, for example, as 45 ones as well as 4 tens and 5 ones.
When objects are grouped in tens, use deliberate errors and discussion to draw attention to the total number of ones represented by the number, so children are familiar with recognising both the extra ones and the total number of ones in a number.
