🌟 Overview
Focuses on additive patterns that increase or decrease by a constant amount. In Year 2, students learn to recognise, describe and create these patterns using numbers, shapes and objects, and to identify any missing elements in the pattern.
This topic works well as a hands-on algebra page because students can build patterns, talk about the rule, and check whether the amount stays the same each time.

| Step | Lesson | What You Learn |
|---|---|---|
| 1 | 🔢 Year 2 Number Patterns: Create, Describe & Find Missing Numbers | Students look for patterns in the environment, such as windows, wheels, or train carriages, and record what they notice in a table or diagram. |
| 2 | 🔍 Year 2 Number Patterns: Find the Rule & Missing Numbers 🌟Coming Soon🌟 | Students identify the constant amount being added or subtracted and use it to complete pattern sequences. This helps them solve missing-number problems and check whether a pattern is increasing or decreasing by the same amount each step |
📚 Curriculum Reference
This topic aligns with the Australian Curriculum Version 9 Year 2 Mathematics content descriptor AC9M2A01: “Recognise, describe and create additive patterns that increase or decrease by a constant amount, using numbers, shapes and objects, and identify missing elements in the pattern”.
It sits within Year 2 Algebra and supports early patterns and algebraic thinking, including recognising structure, describing rules and extending sequences

📝 Helpful Tips
- Use concrete materials first (counters, blocks, objects), then move to drawings and number sequences so students can see the pattern changing.
- Keep language simple and consistent by repeating the rule aloud, such as “add 2 each time” or “subtract 1 each time”.
- For stronger engagement, use real objects from the classroom or playground, then challenge students to create their own pattern for a partner to continue.
- Use tables, diagrams and coloured counters to help students visualise the pattern before they write it, especially for those who need extra support.
