Stage 3 Maths – Expanded Notation & Sequencing Numbers (RN16)

Explicit Teaching Slides + Differentiated Worksheets + Place Value Scaffold

Teaching expanded notation and sequencing large numbers can feel overwhelming — especially when students are still developing confidence with place value.

This 2-day explicit teaching sequence walks students step-by-step through partitioning numbers up to twelve digits, writing numbers in expanded form, reconstructing numbers from expanded notation, and identifying numbers before and after using place value understanding.

Everything is structured using a clear I Do – We Do – You Do approach, so you can model, guide and gradually release responsibility with confidence.

What’s Included

✔️ 2-Day Explicit Teaching PowerPoint

• Fully scripted teacher modelling
• Clear learning intentions & success criteria
• Step-by-step partitioning using place value houses
• Expanded notation (standard & non-standard)
• Reconstructing numbers from expanded form
• Before/after practice (1 / 10 / 100 / 1 000 / 100 000 / 1 000 000 more or less)
• Internal and lexical zero modelling
• Built-in checking-for-understanding opportunities

Differentiated Worksheets (Support, Core & Extension)

• Clear, explicit instructions for every question
• Structured partitioning practice
• 9-digit and 12-digit expansion
• Before/after sequencing tasks
• Reconstructing from expanded notation
• Internal zero challenges
• Non-standard partitioning & reasoning tasks
• Rich task for deeper understanding

Learning Focus

Students will learn to:

• Partition numbers up to twelve digits into expanded notation

• Identify the place value parts of large numbers

• Understand internal and lexical zeros

• Reconstruct numbers from expanded form

• Identify numbers that are 1, 10, 100, 1 000, 100 000 or 1 000 000 more or less

• Regroup and partition numbers in flexible ways

Why Teachers will love this resource:

✔️ Fully scripted modelling — no guesswork

✔️ Clear success criteria embedded throughout

✔️ Strong differentiation for mixed-ability classes

✔️ Zero-prep — just open and teach

✔️ Builds deep place value understanding, not just procedural skill

This isn’t just a worksheet pack — it’s a structured 2-day mini-unit that builds real conceptual understanding of expanded notation and large number sequencing.

Perfect to follow on from a Representing Numbers unit (like RN15) or as a standalone expanded notation sequence.
