Over the half term we have covered numbers 1 – 5. For each number we have looked at how many, counted objects, compared numbers using the language – bigger, smaller, ordered the numbers, found one more and one less, identified missing numbers in a line up of 0-5, looked at shapes – linked triangle to 3, square and rectangle linked to to 4, subitised with amounts to 5 (daily).
What is subitising? –

This week the children have looked at:
• Different ways of arranging blocks to 5
• Conservation of number – different arrangement of blocks but the number remains the same
Year 1: Partitioning a whole number into parts
• Conservation of number – a number can be partitioned but the whole
(total) remains the same.
The Year 1 children have investigated the parts of numbers to 5 and recorded numbers sentences to show what the understand and have found out.
We have used the rhymes – 5 Little Ducks, 5 Speckled Frogs and 5 Apples on a tree to help with the idea that the number stays the same – There are 5 ducks altogether, 2 are in the pond and 3 have gone over the hill etc.
