# Mathematics – Stage 1 – Year A – Unit 2

Patterns have something that repeats over and over and over again – this unit further develops students’ knowledge, skills, and understanding of patterns.

Mathematics K-2 Syllabus © 2021 NSW Education Standards Authority (NESA) for and on behalf of the Crown in right of the State of New South Wales.

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.
