Numbers and Place Value

Overview

This 60-minute lesson for Year 4 pupils focuses on solving number and practical word problems involving place value, representing, ordering, comparing numbers to 1000, partitioning numbers to 1000, and rounding to the nearest 10, 100, and 1000. The lesson closely follows the National Curriculum for England and aligns with the White Rose Maths Scheme of Learning (Block: Number – Place Value).

National Curriculum Links

• Number and Place Value (Year 4)
  • Count in multiples of 6, 7, 9, 25 and 1000
  • Find 1000 more or less than a given number
  • Recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones)
  • Order and compare numbers beyond 1000
  • Round any number to the nearest 10, 100, or 1000
  • Solve number and practical problems involving these ideas

Learning Objectives

By the end of the lesson, pupils will:

1. Represent numbers up to 1000 in different ways (including place value charts and number lines).
2. Partition numbers up to 1000 into thousands, hundreds, tens, and ones.
3. Order and compare numbers beyond 100 using >, < and = symbols confidently.
4. Round numbers to the nearest 10, 100, and 1000 accurately.
5. Solve number and word problems involving these skills.

Resources Needed

• Whiteboard and coloured pens
• Place value charts (individual and class size)
• Number cards (0-9) for ordering activity
• Worksheets with practical word problems
• Small whiteboards and pens for AFL activities
• Number lines (0-1000) displayed in class
• Visual aids for rounding (e.g., rounding rockets or journey themed images)

Lesson Structure

Introduction (10 minutes)

Engage & ‘Wow’ Starter:

• Begin with a quick interactive game, "Place Value Detectives." Display a number (e.g., 458) on the board. Pupils quickly shout out the value of each digit.
• Show three different representations of the number (place value chart, expanded form, number line) and discuss how these all represent the same number.
• Questioning:
  • What is the value of the digit 4?
  • Can you show 458 on a number line?
  • How else could you write this number?
• AfL: Quick Think-Pair-Share
  • Pupils discuss with a partner how to represent 536 differently and share briefly with the class. Teacher circulates to listen for misconceptions.

Teaching & Modelling (20 minutes)

Step 1: Representing and Partitioning Numbers to 1000

• Model representing 763 using place value chart, expanded notation (700 + 60 + 3), and base-10 blocks.
• Show how to partition numbers by physically separating place value parts.
• AfL: Mini Whiteboard Check
  • Teacher says a number verbally (e.g., 482) and pupils write expanded form on mini whiteboards. Quick whole-class feedback.

Step 2: Comparing and Ordering Numbers

• Model comparing two numbers first (e.g., 465 and 546). Use symbols >, <, = with reasoning.
• Increase difficulty by comparing three numbers and ordering them. Use number cards for a physical ‘ordering race’.
• AfL: Targeted Questioning
  • Ask: Which is the largest number here? Why? What does the digit in the tens place tell you about these numbers?

Step 3: Rounding Numbers

• Model rounding numbers to the nearest 10 (e.g., round 562). Use number lines and introduce the concept of ‘the rounding rocket’ that lands at the closest multiple of 10.
• Increase complexity: round to nearest 100 and then 1000, showing number line jumps.
• AfL: True/False Quiz
  • I say: “682 rounded to the nearest 100 is 600.” Pupils hold up T or F cards.

---

Guided Practice (15 minutes)

• Pupils work in pairs on word problems that require:

  1. Representing numbers in different ways.
  2. Partitioning numbers to solve.
  3. Ordering sets of 3-4 numbers.
  4. Rounding numbers to the nearest 10, 100 or 1000 within a problem context (e.g., “Estimate the crowd at a stadium”).

• Examples include:

  • Jamie has 483 marbles and Sara has 572. Who has more marbles?
  • Round 376 to the nearest 100 to estimate how many people are attending a concert.

• Teacher circulates and uses AfL: Observational Assessment for misconceptions and correct reasoning.

---

Independent Practice (10 minutes)

• Pupils complete varied questions on their worksheets individually:
  • Partitioning numbers in different formats.
  • Using >, <, = to compare numbers.
  • Rounding numbers to the nearest 10, 100, or 1000.
• AfL: Exit Tickets
  • Pupils write one number rounded to nearest 10, one ordered set of numbers, and one partitioned number to hand in for teacher assessment.

---

Plenary (5 minutes)

• Recap the key learning points using a fun, fast-paced quiz format on the whiteboard:
  • Show a number, ask pupils to shout out the partition.
  • Ask for the rounded number to nearest 1000.
  • Which number is bigger: 839 or 893?
• End with posing a “Challenge Question” for early finishers or home learning:
  • If a number rounds to 400 when rounded to the nearest 100, what could the number be?
• Highlight excellent answers and provide next steps.

Assessment for Learning (AfL) Points Summary

• Think-Pair-Share: Early formative assessment of understanding representations of numbers.
• Mini Whiteboards: Instant feedback on partitioning skills and expanded notation.
• Targeted Questioning: Throughout modelling to check grasp of ordering and comparing.
• True/False Cards: Quick assessment of rounding concepts.
• Observation: While pupils work in pairs to catch misconceptions early.
• Exit Tickets: Summative assessment to guide next steps and interventions.

---

Differentiation

• Support:
  • Use concrete manipulatives (base 10 blocks) to aid understanding.
  • Provide sentence starters for explaining reasoning.
• Challenge:
  • Introduce numbers beyond 1000 for ordering and rounding.
  • Word problems with multi-step reasoning, integrating addition/subtraction estimation.
