In this unit, students will learn to:

- understand that patterns have an element of repetition, meaning something repeats over and over and over again
- recognise that the repeating element in a pattern can be called the repeating core
- use the pattern core to create patterns, extend the patterns of others, and identify the missing elements within patterns
- develop an understanding that number bonds and dice structures are forms of mathematical patterns we trust
- understand that some patterns grow (the pattern increases by the same amount in each subsequent term) and shrink (the pattern decreases by the same amount in each subsequent term)
- identify, describe, and create patterns when counting forwards or backwards in twos, fives, and tens
- use objects, pictures, words, and numbers to represent and prove ideas
- apply knowledge of counting sequences to solve problems involving equal groups.
