IB Maths MYP Year 1, Unit 1 Slidedeck Bundle

**Teach IB Maths MYP Year 1 Unit 1 – Number Systems and Operations with a complete bundle containing all 10 slide decks from 1.1.1 to 1.1.10.** Students learn how to: • Read, write, and represent whole numbers and decimals using standard, word, and expanded form • Use place value and powers of ten to explain the value of digits • Compare and order whole numbers, decimals, and negative numbers • Round numbers to decimal places and significant figures • Estimate answers and judge whether results are reasonable • Identify factors, multiples, prime numbers, and divisibility rules • Use prime factorisation to find the HCF and LCM • Represent and calculate with positive and negative integers • Apply the order of operations, including grouping symbols and powers • Convert between fractions, decimals, and percentages • Recognise and justify equivalent numerical representations • Add, subtract, multiply, and divide fractions • Add, subtract, multiply, and divide decimals • Find percentages of quantities using mental strategies and multipliers • Apply number skills to money, measurement, energy, and other real-world contexts • Identify and correct common calculation errors • Communicate mathematical reasoning using diagrams, number lines, tables, and written explanations • Explore patterns, make conjectures, and justify conclusions through inquiry activities The bundle includes: 1. **1.1.1 Place Value and Number Representation** 2. **1.1.2 Comparing and Ordering Numbers** 3. **1.1.3 Rounding and Estimation** 4. **1.1.4 Factors, Multiples, and Prime Numbers** 5. **1.1.5 Integer Operations** 6. **1.1.6 Order of Operations** 7. **1.1.7 Fractions, Decimals, and Percentages** 8. **1.1.8 Fraction Operations** 9. **1.1.9 Decimal Operations** 10. **1.1.10 Percentages of Quantities** 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 1 – Number Systems and Operations, with a focus on the key concept of Logic, the related concepts of Quantity, Representation, Equivalence, Approximation, Patterns, and Systems, and MYP Criteria A, B, C, and D.**
