1 more, 1 less

This week, in maths, the Ducklings have been learning about 1 more and 1 less. They have been finding out what 1 more or 1 less than an amount is by adding one more object or taking one away. Some us have been confident to identify numbers that are missing from a number line and can give the reasons for their answers using the vocabulary of 1 more and 1 less.
