Student lesson
Words to know
1,000 thousands.
A symbol 0 to 9.
A group of three digits.
Say which is greater.
1. Discover: city populations
A city has 4,305,206 people. How do you say that number?
2. Understand: large numbers
- 4,305,206 is four million, three hundred five thousand, two hundred six.
- Commas split the digits into periods of three.
- Compare from the left: 4,305,206 > 4,299,999 because 4 million 3 hundred thousand beats 4 million 2 hundred thousand.
- Rounded to the nearest million: 4,000,000.
3. Explore: say it
You need paper.
- Split into periods.
- Read each period.
- Add its name.
- Say the whole number.
Think about it: what did you notice?
Four million, three hundred five thousand, two hundred six.
4. Practise
Guided practice
Question 1. Digits in a million?

Answers are in the answer key below. Try first, then check.
5. Apply: everyday mathematics
One town has 2,450,000 people and another 2,405,000. Which is larger?
Show a sample answer
The first, 2,450,000.
6. Common mistake
Fix: A million has seven digits: 1,000,000.
7. Check and master

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Read numbers in millions | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Write numbers in words and digits | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Compare large numbers | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O4 Round large numbers | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
Proposed Courseversity thresholds for this page: Bronze = at least 3 of 5 core questions correct; Silver = all 5; Gold = all 5 plus the challenge. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: Writing a million as 100,000. A million has seven digits: 1,000,000.
- Explain another way: use real objects first, then pictures.
- Show a simpler example: Numbers to 100,000.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: read numbers in millions; write numbers in words and digits; compare large numbers; round large numbers.
Prerequisite knowledge. Grade 5 place value.
Materials. Counters (stones, seeds or bottle tops), paper, pencils, board or chalkboard. Low-resource options: use stones, seeds, sticks, bottle tops or drawings in the sand or on the board instead of printed materials.
Preparation. Gather the counters and draw the example pictures on the board before the lesson.
Suggested duration. 35–45 minutes.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Start with the Discover situation and let learners suggest ideas before you teach.
Explanation (10 min). Teach the Understand section with real objects first, then pictures, then symbols and words.
Guided activity (10 min). You need paper. Learners follow the Explore steps in pairs.
Independent activity (10 min). Learners complete the independent practice and the worksheet.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Teacher explanation notes. Use the concrete, pictorial, abstract order: real objects first, then pictures, then symbols and words. Return to real objects whenever a learner needs support.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and work with a partner; say each step aloud together. Extension. Ask learners to make up their own example and explain it to a partner.
Formative assessment. Listen to learner explanations, ask “how do you know?”, and check the independent work.
Misconceptions. Writing a million as 100,000. A million has seven digits: 1,000,000.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz and worksheet on this page. The 10-mark scheme and all answers are in the answer key above. Re-check every answer and the marking scheme before publication.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Numbers to 100,000. Enrichment. Invite learners to find or create three more examples at home or in the classroom and explain them. Homework. See above.
Teacher reflection. After teaching, record: which concepts learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
