IB Maths MYP Year 1, Unit 2 - 1.2.1 Variables and Algebraic Notation

IB Maths MYP Year 1, Unit 2 Slidedeck Bundle

**Teach IB Maths MYP Year 1 Unit 2 – Algebraic Thinking and Patterns with a complete bundle containing all 8 slide decks from 1.2.1 to 1.2.8.** Students learn how to: • Use variables, coefficients, constants, and algebraic notation • Substitute values into expressions and evaluate results • Collect like terms and simplify algebraic expressions • Solve and check one-step equations • Represent function machines using inputs, outputs, and rules • Identify terms, positions, and patterns in number sequences • Find common differences and describe arithmetic sequences • Represent sequences using tables, diagrams, words, and formulas • Write and apply general rules to find any term • Interpret inequality symbols in context • Represent inequalities on number lines using open and filled dots • Solve and check simple one-step inequalities • Apply algebraic thinking to money, capacity, design, measurement, and other real-world contexts • Identify and correct common algebraic errors • Communicate reasoning using equations, tables, diagrams, number lines, and written explanations • Explore patterns, make conjectures, and justify conclusions through inquiry activities The bundle includes: 1. **1.2.1 Variables and Algebraic Notation** 2. **1.2.2 Substitution into Expressions** 3. **1.2.3 Collecting Like Terms** 4. **1.2.4 One-step Equations** 5. **1.2.5 Function Machines** 6. **1.2.6 Number Sequences** 7. **1.2.7 Describing General Rules** 8. **1.2.8 Simple Inequalities** Use alongside this suggested IB Maths MYP curriculum map: [IB Maths MYP Curriculum Map](https://docs.google.com/spreadsheets/d/1QnWSTHUj95ZkpCW7dzpeFoO-WnHiJ9pF8EldCU9y61E/edit?gid=1105657443#gid=1105657443) Please note that this curriculum map is not an official IB publication or a compulsory sequence prescribed by the IB. It presents one possible way to organise and cover the MYP mathematics branches, concepts, global contexts, and assessment criteria across Years 1–5. Schools and teachers should adapt the sequence, timing, and emphasis to suit their students and local curriculum requirements. **Designed around IB Maths MYP Year 1 Unit 2 – Algebraic Thinking and Patterns, with a focus on the key concept of Relationships, the related concepts of Patterns, Generalization, Representation, and Logic, and MYP Criteria A, B, and C.**
