Objective and success criteria
Students will: Skip count by 5s, 10s and 100s from any number.
- 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: Skip count by 2s, 5s, 10s and 100s; Count in tens from any number
Leads to: Find the rule of a number pattern
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 (Skip count by 2s, 5s, 10s and 100s; Count in tens from any number). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Count by 2s. What is missing? 12, 14, 16, __, 20 → 18Prompt: How much does the count go up each time?
- Count on in tens: 22, 32, 42, __, 62 → 52Prompt: The ones digit stays the same each time.
- Count back by 10s: 50, 40, 30, 20, __ → 10Prompt: Each number is less than the one before. By how much?
Hook · 6 min
- Show a number in the news or a price tag and ask what each digit is worth.
- Share the objective: Skip count by 5s, 10s and 100s from any number. 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: Count in hundreds: 539, 639, __, 839, 939
- Step 1: 639 + 100 = 739
- Step 2: 739
- Answer: 739
- 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.
- Count in hundreds: 323, __, 523, 623, 723 → 423Prompt: Only the hundreds digit changes.
- Count in tens: 887, 897, 907, __, 927 → 917Prompt: The ones digit stays the same.
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.
- Count in tens: 887, 897, 907, 917, __ → 927Prompt: The ones digit stays the same.
- Count in hundreds: 112, 212, __, 412, 512 → 312Prompt: Only the hundreds digit changes.
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: Skip count by 2s, 5s, 10s and 100s.
- 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: Find the rule of a number pattern.
- 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.
