Objective and success criteria
Students will: Read and write number words to 1000.
- 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 number words to 100; Hundreds, tens and ones
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 · 4 min
- Quick retrieval from earlier learning (Read and write number words to 100; Hundreds, tens and ones). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Write "nineteen" in digits. → 19Prompt: The first part of the word tells the tens.
- Which is the word for 36? (forty-six / thirty-six / thirty / sixty-three) → thirty-sixPrompt: 36 has 3 tens. Find the word that starts with that tens word.
- Write "fifty-four" in digits. → 54Prompt: The first part of the word tells the tens.
Hook · 3 min
- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: Read and write number words to 1000. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Write "one hundred seventy-nine" in digits.
- Step 1: "one hundred seventy-nine" = 179
- Answer: 179
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 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 "eight hundred two" in digits. → 802Prompt: Find the hundreds word first.
- Which number is "two hundred seven"? (2007 / 270 / 27 / 207) → 207Prompt: There is no tens word. What goes in the tens place?
You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which is the word name for 121? (one hundred twenty-one / two hundred eleven / one hundred twelve / two hundred twenty-one) → one hundred twenty-onePrompt: Read the hundreds, then the tens, then the ones.
- Which number is "nine hundred three"? (930 / 93 / 309 / 903) → 903Prompt: There is no tens word. What goes in the tens place?
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 number words to 100.
- 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.
