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: six thousand seven hundred seventy-one → 6771Prompt: The word 'thousand' tells you the first digit.
- In 859 436, which place is the digit 4 in? (ten thousands / ones / thousands / hundreds) → hundredsPrompt: The places in a group of three are hundreds, tens, ones — for thousands too.
- How do you write 2352 in words? (two thousand five hundred thirty-two / two thousand four hundred fifty-two / two thousand three hundred sixty-two / two thousand three hundred fifty-two) → two thousand three hundred fifty-twoPrompt: 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 fifty-four thousand five hundred twenty-seven → 754527Prompt: Everything before 'thousand' is the thousands group.
- Which number is one hundred twenty-three thousand ten? (124 000 / 12 310 / 123 010 / 123 100) → 123 010Prompt: 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: nine hundred four thousand three hundred twenty-eight → 904328Prompt: Everything before 'thousand' is the thousands group.
- Which number is eight hundred eighty thousand twenty-nine? (88 029 / 880 290 / 882 900 / 880 029) → 880 029Prompt: 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.
