Comparing Numbers Deep Dive

Overview

This 55-minute lesson is designed for Year 2 pupils (ages 6–7) to deepen their understanding of comparing numbers within 100, using symbols (<, >, =), and developing their mathematical language. The activities integrate visual and kinaesthetic learning approaches to engage the class of 8 students. This plan aligns explicitly with the National Curriculum for England - Year 2 Mathematics, Number and Place Value strand.

National Curriculum Links

Key Stage 1 - Mathematics - Number and Place Value

• Pupils should be taught to:
  • Compare and order numbers from 0 up to 100; use <, >, = signs (NC 2014)
  • Recognise the place value of each digit in a two-digit number (tens, ones) (NC 2014)
  • Count in steps of 2, 3, and 5 from 0, and in tens from any number, forward and backward (linked for reinforcement) (NC 2014)

Mathematical Language Focus:

• Greater than, less than, equal to, more than, fewer than.

Learning Objectives

By the end of this lesson, pupils will be able to:

1. Confidently compare two numbers up to 100 using <, >, and = symbols.
2. Articulate their reasoning verbally using correct mathematical vocabulary (“greater than”, “less than”, “equal to”).
3. Recognise and explain the place value of the digits in two-digit numbers to assist comparison.
4. Apply understanding of number order and place value through hands-on activities.

Resources

• Large number cards (0–100) printed with tens and ones clearly separated
• Visual place value charts for each student
• Sets of small counters (preferably in two colours)
• Balance scales (toy or cardboard crafted)
• Whiteboards + pens for each child
• Worksheet with number pairs for comparing (with space for symbols and reasoning)
• Large <, >, = symbols on cards
• A digital interactive number line (projected, if possible)

Lesson Structure

1. Introduction (10 minutes)

• Begin with a quick warm-up: counting in tens and ones from different numbers (e.g. 47, then 57, then 67). Use the visual place value charts.
• Recap the meaning of <, >, and = symbols with physical symbol cards. Invite 2 pupils at a time to hold them up as you show pairs of number cards.
• Introduce today’s objective: “Today we will become experts at comparing numbers and explain why!”

2. Direct Teaching and Modelling (10 minutes)

• Using a pair of 2-digit number cards (e.g. 43 and 37), model how to compare by first looking at the tens digit, then the ones digit if needed.
• Draw the number on the whiteboard, split into tens and ones, to emphasise place value.
• Show how to write the correct symbol between the numbers and say a full sentence, e.g. “43 is greater than 37 because four tens are more than three tens.”
• Demonstrate this process with 3 different pairs with increasing difficulty (e.g. 51 and 59; 64 and 64).

3. Guided Practice (15 minutes)

• Split into pairs (or individual if preferable). Each pupil picks two number cards and uses the place value chart and counters to represent each number physically (e.g., 4 counters for the tens, 3 counters for ones).
• Pupils then use a balance scale to see which side is heavier (representing greater number). This concrete visual supports their understanding.
• After comparing, pupils record the pair, the symbol, and a short sentence explaining their choice on their whiteboards or worksheet.
• Teacher circulates, offering scaffolding – prompting “What do the tens look like? Are they equal? What about the ones?"
• Select 2-3 pupil examples to share with whole class, praising clear explanations.

4. Independent Application (15 minutes)

• Students complete a short worksheet with 10 pairs of numbers to compare. They:

  • Write the correct symbol (<, >, =)
  • Use counters to check their thinking
  • Write one sentence per pair explaining their choice, e.g. “72 is less than 79 because two ones are fewer than nine ones.”

• Encourage neat, clear sentences and use of place value language.

5. Plenary and Assessment (5 minutes)

• Round-robin game: Each pupil reads out one of their sentences, and the class holds up the symbol card that matches their statement.
• Quick verbal quiz: Ask pupils to order a set of four numbers from smallest to largest, explaining their reasoning.
• Teacher notes which pupils grasp work confidently and who may need further support.

Differentiation

• Support: Use fewer pairs of numbers and concrete objects only. Support sentences with sentence starters: “___ is greater than ___ because...”
• Challenge: Compare numbers with missing digits for them to infer (e.g. 4_ and 43), or extend to three-digit numbers with scaffolding if appropriate. Introduce the concept of comparing number sequences rapidly.

Assessment Notes

• Monitor pupils’ explanations for correct use of <, >, and = symbols and clear reasoning.
• Listen for confidence in mathematical vocabulary during class discussions and plenary.
• Use worksheet responses to assess independent application and identify any misconceptions about place value.

Additional Creative Ideas to Wow

• Use physical “human number cards” where two pupils each wear a two-digit number, and the rest of the class act as the “symbol” to decide the relationship.
• Integrate a simple interactive story or video involving characters comparing treasures or objects to contextualise numbers.
• Create a “Maths Detective” theme where pupils must “solve” the mystery by correctly comparing clues (numbers).

This lesson provides a multi-sensory, scaffolded approach to comparing numbers, precisely aligned with the National Curriculum requirements and tailored for year 2 learners’ developmental stage.
