# Ordering and Sequencing

### Ordering and sequencing number activities provide opportunities both to recognise a number sequence and complete a sequence of numbers.

Recognition of numbers supports the development of number skills such as counting forwards, backwards and skip counting.

Charlie said, I helped Billy put the numbers in order.  We counted the numbers up to 20.

The key idea of number knowledge at Level 1 is that the objects in a set can be counted. At level 1 students are learning to count with understanding and identify ‘how many’ are in sets of objects. Once students can count by ones independently, they can learn to count forwards, backwards and start skip counting.

Andi said, We used the 100’s board to see where the numbers had to go.

Room 15 and 16 have been learning to recognise their numbers by reading them, writing them and ordering them correctly to 20.  This will help them to understand the size of the number in relation to other numbers. Counting can begin with any number in a set with the last counting number telling us how many are in the set.

Jackson said, We started from the biggest number, which was 20, and we  counted backwards to 1.

They worked with a buddy so they could help each other to find the number and check the numbers were in the right order.  This supported great collaborative work, problem-solving and mathematical discussions.

Thea said, Kian helped me put my numbers in the right order.  We counted up to 20 together.

The next steps in our mathematical learning will be to read, write, count and order all our numbers to 100 and beyond.
