Objective and success criteria
Students will: Multi-digit multiplication.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Multiply two-digit by two-digit numbers
Leads to: the next skill in this area.
Materials: Counters for arrays, Multiplication grid, Base-ten blocks, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Multiply two-digit by two-digit numbers). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Use long multiplication: 30 × 97 → 2910Prompt: Multiply 30 by the ones digit of 97.
- Use long multiplication: 41 × 43 → 1763Prompt: Multiply 41 by the ones digit of 43.
- Use long multiplication: 81 × 49 → 3969Prompt: Multiply 81 by the ones digit of 49.
Hook · 5 min
- Show an array of chairs, eggs or windows and ask how many there are without counting one by one.
- Share the objective: Multi-digit multiplication. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: 131 × 54 = ?
- Step 1: 131 × 4 = 524
- Step 2: 131 × 50 = 6550
- Step 3: 524 + 6550 = 7074
- Answer: 7074
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- 104 × 17 = ? → 1768Prompt: Multiply 104 by 7, then by 10.
- A school orders 12 tablets for its library. Each one costs $270. What is the total cost? (Type the number only.) → 3240Prompt: Multiply the price by the number of tablets.
You do: independent practice · 10 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- 151 × 90 = ? → 13590Prompt: Multiply 151 by 0, then by 90.
- A school orders 18 tablets for its library. Each one costs $433. What is the total cost? (Type the number only.) → 7794Prompt: Multiply the price by the number of tablets.
Watch out for
- Thinking multiplying always makes a number bigger.
- Dropping a zero in long multiplication when moving to the tens row.
Support and stretch
Support
- Review first: Multiply two-digit by two-digit numbers.
- Use concrete materials: counters for arrays.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
