Multiplication Magic: Two-Digit Numbers
Year 5 Mathematics Learning to multiply two-digit by one-digit numbers Using the vertical-column method
Learning Intentions
Use the vertical-column method to multiply two-digit by one-digit numbers Understand place value in multiplication Solve real-world word problems Work collaboratively with peers Use correct mathematical vocabulary
Warm-Up: Multiplication Facts Recall
Skip count by 4s, 6s, 7s, 8s, 9s Quick multiplication facts practice Connect to families of facts Use multiplication grid for reference
Place Value Review
Two-digit numbers have tens and units 34 = 3 tens + 4 units 30 + 4 = 34 Place value helps us multiply efficiently
The Vertical-Column Method
Set up: units under units, tens under tens Step 1: Multiply the units first Step 2: Multiply the tens Step 3: Add any carried numbers Write your final answer
Guided Practice in Pairs
Work with your partner on these problems: 26 × 4 43 × 9 52 × 3 Use whiteboards to show your working Explain your steps to each other
Real-World Problem Solving
A carton holds 27 bottles. How many bottles are in 5 cartons? Work with your partner to: • Write this as a multiplication equation • Solve using the vertical method • Check your answer makes sense
Problem-Solving Strategies
{"left":"Break numbers into tens and units\nUse known multiplication facts\nEstimate first to check answers","right":"Work systematically step by step\nUse the vertical-column method\nCheck your working carefully"}
Group Discussion Time
Share your solutions with another pair Explain the strategy you used Listen to other approaches Use mathematical vocabulary: • multiply, product, place value, carry, estimate
Independent Practice
Complete the worksheet problems Show all your working Use the vertical-column method Check your answers with estimation Attempt the word problems too
