Divide By 5
Divide by 5
What you'll learn
- Divide by 5 using the 5-times table backwards.
- Spot numbers that divide evenly by 5 — they end in 0 or 5.
- Sharing rupee coins in fives and making groups of 5.
- Connect to Math Mela money and grouping problems.
Key concepts
Level 1 — Core idea
Verbal: 25 ÷ 5 asks: how many fives make 25?
Symbolic: 25 ÷ 5 = 5 because 5 × 5 = 25.
Visual: Make groups of 5 dots from 25 → count 5 groups.
Level 2 — Going deeper
Numbers ending in 0 or 5 are divisible by 5. For 35 ÷ 5, think 5 × 7 = 35.
NCERT anchor
NCERT Math Mela, Class 3 — Chapter 5 uses groups of 5 and 10. Counting ₹5 coins to pay ₹35 links to 35 ÷ 5 = 7 coins.
Worked example
35 ÷ 5 = ?
Step 1 — How many 5s in 35?
Step 2 — 5, 10, 15, 20, 25, 30, 35 → seven 5s
Step 3 — Or: 5 × 7 = 35
Answer: **7**
Share 45 marbles equally among 5 children.
Step 1 — 45 ÷ 5 = ?
Step 2 — 5 × 9 = 45
Answer: **9 marbles each**
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| 25 ÷ 5 = 4 | Wrong table fact | 5 × 5 = 25 |
| 33 ÷ 5 = 6 exactly | Ignoring remainder 3 | 33 ÷ 5 = 6 r 3 |
| Only checking last digit for × not ÷ | Not using inverse | Use 5-times table backwards |
| Confusing ÷5 with ÷2 | Mixing operations | ÷5 → groups of five |
Quick check
- 40 ÷ 5 = ?
- Which divides evenly: 22 or 25?
- 5 children share 30 sweets — each gets?
- Stretch: 50 ÷ 5 = ? and 50 ÷ 10 = ? — compare.
Revision tip: Pair each ÷5 answer with its ×5 fact on flashcards.

Interactive Exploration Suggestions (Drishti Live Worlds)
- Use the platform-native live simulation or PhET-style tool for this topic (number line, Venn, physics playground, molecule builder, sensor dashboard, etc.).
- Mirror / body / home activity: physically do the concept (count objects, measure, role-play) and photograph or describe for portfolio.
- Voice or text reflection with AI Mentor: explain the concept to a younger student or family member.
AI Mentor Prompts (Socratic, Board-Adaptive)
- "Explain this concept to a Class 6 student using one real example from an Indian home, school, market, or festival."
- "What is one common mistake students make here, and how would you catch yourself making it?"
- Stretch: "How does this connect to coding, robotics, money, health, environment, or a future career?"
Gamification, Portfolio & Parent Visibility
- Complete the core practice + one extension activity (photo, table, short reflection, or mini-project) for base XP + topic badge.
- 5-7 day streak or family discussion note = multiplier + visible artifact in parent/principal dashboard.
- Best real-world application stories (anonymised) featured on class or national leaderboard.
Robotics, STEM & Future Skills Bridges
- One hands-on project or measurement using the Drishti kit or household items that makes the concept physical.
- Direct link to at least one Future Skill track (Money Management, Green Tech, Cyber Defenders, Micro-Entrepreneurship, AI Mastery, Sustainable Living, Personality Development).
- Coding extension where relevant (simple script, simulation, or data logging).
