A digit is worth ten times the place to its right
Number sense
CCSS 4.NBT.A.1England: Y5 Number and place value
Objective and success criteria
Students will: A digit is worth ten times the place to its right.
- 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: Place value names up to hundred thousands
Leads to: Multiply whole numbers by 10, 100 and 1000
Materials: Place value chart, Base-ten blocks or a number line, Mini whiteboards and pens, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Place value names up to hundred thousands). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- In 529 178, which place is the digit 8 in? (hundreds / ten thousands / ones / tens) → onesPrompt: The places in a group of three are hundreds, tens, ones — for thousands too.
- What is the value of the digit 9 in 46 927? → 900Prompt: Name the place of the digit first.
- In 240 516, which place is the digit 2 in? (thousands / ten thousands / ones / hundred thousands) → hundred thousandsPrompt: The places in a group of three are hundreds, tens, ones — for thousands too.
Hook · 6 min
- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: A digit is worth ten times the place to its right. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: The value of 8 in 8000 is how many times the value of 8 in 800?
- Step 1: 8000 ÷ 800
- Step 2: 10
- Answer: 10
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- The value of 1 in 100 000 is how many times the value of 1 in 1000? → 100Prompt: Each place to the left is worth ten times as much.
- How many tens are there in 163 altogether? → 16Prompt: Count every 10 in the number, not just one digit.
You do: independent practice · 17 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 · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- How many tens are there in 41 200 altogether? → 4120Prompt: Count every 10 in the number, not just one digit.
- What number is 68 tens? → 680Prompt: One ten is 10.
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: Place value names up to hundred thousands.
- 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
- Move on to: Multiply whole numbers by 10, 100 and 1000.
- 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.
