Objective and success criteria
Students will: Compare two-digit numbers with <, > and =.
- 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: Compare two-digit numbers
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 (Compare two-digit numbers). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Choose the sign that makes this true: 85 __ 97 (< / > / =) → <Prompt: Compare the tens first.
- Choose the sign that makes this true: 14 __ 14 (< / > / =) → =Prompt: Compare the tens first.
- Choose the sign that makes this true: 87 __ 57 (< / > / =) → >Prompt: Compare the tens first.
Hook · 3 min
- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: Compare two-digit numbers with <, > and =. 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: Choose the sign: 31 __ 46
- Step 1: 31 < 46
- Answer: <
- 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.
- Choose the sign: 48 __ 17 (< / > / =) → >Prompt: Compare the tens first.
- Choose the sign: 2 tens and 4 ones __ 18 (< / > / =) → >Prompt: First write the tens and ones as a number.
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.
- Choose the sign: 3 tens and 6 ones __ 32 (< / > / =) → >Prompt: First write the tens and ones as a number.
- Choose the sign: 65 __ 86 (< / > / =) → <Prompt: Compare the tens first.
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: Compare two-digit numbers.
- 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.
