Number sense
CCSS 4.NBT.A.2England: Y5 Number and place value
Objective and success criteria
Students will: Read and write numbers to 1 000 000 in words.
- 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: Read and write four-digit numbers in words; Place value names up to hundred thousands
Leads to: the next skill in this area.
Materials: Place value chart, Base-ten blocks or a number line, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Read and write four-digit numbers in words; Place value names up to hundred thousands). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Write in digits: three thousand three hundred twenty-six → 3326Prompt: The word 'thousand' tells you the first digit.
- In 170 463, which place is the digit 7 in? (thousands / tens / ten thousands / ones) → ten thousandsPrompt: The places in a group of three are hundreds, tens, ones — for thousands too.
- How do you write 2605 in words? (two thousand six hundred five / two thousand sixty-five / two thousand seven hundred five / two thousand six hundred fifteen) → two thousand six hundred fivePrompt: Read the thousands first, then the hundreds, then the last two digits.
Hook · 5 min
- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: Read and write numbers to 1 000 000 in words. 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: Write in digits: four hundred thirty-two thousand seven hundred thirty-one
- Step 1: 432 thousand, then 731.
- Step 2: 432 731
- Answer: 432731
- 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.
- Write in digits: seven hundred twenty-eight thousand six hundred forty-three → 728643Prompt: Everything before 'thousand' is the thousands group.
- Which number is one hundred twenty-three thousand nine? (123 090 / 123 009 / 123 900 / 12 309) → 123 009Prompt: How many thousands are there?
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.
- Write in digits: five hundred thirty-six thousand twenty-nine → 536029Prompt: Everything before 'thousand' is the thousands group.
- Which number is three hundred six thousand eight? (306 800 / 30 608 / 306 080 / 306 008) → 306 008Prompt: How many thousands are there?
Watch out for
- Reading 1,045 as one thousand four hundred five: point to each place and say its value.
- Thinking a longer number is always bigger, even with decimals (0.45 vs 0.5).
Support and stretch
Support
- Review first: Read and write four-digit numbers in words.
- Use concrete materials: place value chart.
- 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.
