National Curriculum Links

• Mathematics Programme of Study (Key Stage 2)
  • Year 3: Multiply two-digit numbers by one-digit numbers, without carrying
  • Year 4: Multiply two and three-digit numbers by one-digit numbers, without carrying

---

Learning Objectives (WALT)

• We Are Learning To:
  • Understand and apply short multiplication methods without carrying
  • Multiply ones first, then tens, maintaining place value (columns/"houses")
  • Solve multiplication problems fluently and reasoning about the process

---

Success Criteria

• I can multiply the ones digit first and then the tens digit separately.
• I keep the digits aligned in their correct place value columns.
• I can solve multiplication problems without carrying over digits.
• I can explain why we multiply ones before tens.

---

Resources

• Mini whiteboards and markers
• Base-10 manipulatives (ones, tens rods)
• Printed worksheets with differentiated multiplication problems
• Visual column method display chart (laminated)
• Exit tickets for assessment

Lesson Breakdown

1. Flashback 4 (5 minutes)

Purpose: Activate prior knowledge and scaffold learning

• All: Calculate 15 × 10 (conceptual understanding of multiplying by 10)
• Year 3: Subtract 45 − 20 (reinforce subtraction fluency)
• Year 4: Subtract 450 − 200 (reinforce understanding of hundreds and tens)
• All: Round 88 to the nearest 10 (supports number sense foundation)

Teacher prompt: Explain how rounding helps in estimating answers to multiplication questions.

Differentiation:

• SEN: Use number lines and place-value charts for rounding support
• Advanced: Ask pupils to round bigger numbers (e.g., 182) to the nearest 10 or 100

2. Introduction to Short Multiplication Concept (7 minutes)

Teaching Points:

• Use visual aids (base-10 blocks) to demonstrate multiplying the ones digit first, then the tens digit.
• Emphasise "houses" or columns — keep digits aligned vertically.
• Model step-by-step on the board with 15 × 10 (starting simple), increasing to 32 × 3 and 212 × 4.
• Use talk partners — pupils explain the importance of place value in multiplication.

Focus:

• Multiply ones first (e.g., 2 × 3 = 6)
• Multiply tens next (3 × 3 = 9 tens = 90)
• Write the partial results in their own columns before summing.

Dyslexia-friendly tips:

• Present numbers in consistent, clear fonts (e.g., Dyslexie or Arial) on worksheets
• Use coloured overlays on multiplication grid columns to keep place values visually separated

---

3. Guided Practice (8 minutes)

• Teacher leads with examples on mini whiteboards:
  • Multiplying 32 × 3
  • Multiplying 212 × 4
• Pupils work alongside the teacher writing partial products in columns.
• Teacher circulates and questions use: “Why do we multiply the ones first? What happens if we don’t keep the digits in their columns?”
• Encourage pupils to say aloud the steps—they verbalise process and reasoning.

Differentiation:

• SEN: Use manipulatives concretely (counting rods/blocks) during calculations
• EAL: Provide stepwise picture cards and simple sentence frames (e.g., "First, multiply...")
• Advanced: Work on two-digit by two-digit multiplication without carrying (if confident)

---

4. Independent Challenge (8 minutes)

Tasks:

• Fluency: Straightforward calculations (e.g., 44×2, 123×3), focusing on neat column alignment and no carrying.
• Problem-solving: Contextualised task (biscuit box problem) where pupils calculate total biscuits in multiple boxes — encourages applying multiplication in real-world scenarios.
• Reasoning: Short written explanation on mini-whiteboards or paper—“Explain why we multiply the ones before the tens.”

Differentiation:

• SEN: Modified numbers with fewer digits or use of calculators to check results after manual multiplication
• Peer pairing for support and discussion
• Advanced: Multiply bigger numbers (e.g., 362×4) without carrying, or explain how “carrying” would change their method

---

5. Plenary / Exit Ticket (2 minutes)

• Quick fire question: 22 × 4 = ? (on mini whiteboards or verbally)
• Collect exit tickets to assess individual understanding.
• Ask 1–2 pupils to explain the column method verbally to the class.

---

Assessment for Learning

• Observe during guided practice: accuracy, methods, verbal reasoning
• Review independent work: fluency, problem-solving, written explanations
• Exit ticket responses
• Questioning during plenary to check conceptual understanding

---

Additional Notes for Teachers

• Emphasise place value by visualising “houses” for ones, tens, and hundreds.
• Avoid carrying in this lesson to build confidence in short multiplication foundations.
• Use manipulatives generously — critical for low attainment learners who missed Year 1 & 2 foundations.
• Reference literacy skills through explaining methods verbally and in writing—supports cross-curricular numeracy and literacy development.

---

Extension Ideas

• Explore multiplying three-digit numbers by 1-digit numbers with carrying (Year 4 challenge).
• Create own word problems using multiplication situations (strengthen reasoning).
• Investigate patterns when multiplying by 10, 100 (link to rounding and place value).

By carefully scaffolding, including multi-sensory approaches and clear focus on place value columns, this lesson plan supports all learners to master short multiplication with confidence and reasoning, in line with the National Curriculum.
