What you'll learn
- To pick subtraction when a problem asks "how many left?" or "how many more?"
- To write a number sentence from a story.
- To solve one-step and two-step stories up to 100.
Key concepts
Verbal: Circle words like left, gave away, sold, remain — they usually mean subtract.
Symbolic: Story → number sentence: "52 shells, gave 18" → 52 − 18 = ?
Level 1 — Key words for "take away"
left, remain, gave away, sold, ate, flew away → usually subtraction.
Level 1 — "How many more?" trick
Ali has 45, Ben has 32. How many more does Ali have? → 45 − 32 = 13 (compare by subtracting smaller from larger).
Level 1 — Draw a bar model
[Total 50] − [Sold 18] = [Left ?]
Level 2 — Two-step (intro)
Had 60, gave 15, then gave 10 more → 60 − 15 − 10 = 35.
Level 2 — Indian stories
Cricket cards, rangoli diyas, school lunch tiffins.
Worked example
Priya collected 52 shells at Marina Beach. She gave 18 to her brother. How many does she have now?
Step 1 — Total shells: 52
Step 2 — Gave away: 18 (subtraction)
Step 3 — 52 − 18 = 34
Answer: 34 shells
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Adding when story says "gave away" | Keyword miss | Gave away → subtract |
| 45 − 32 for "total of both" | Wrong question | Read what is asked |
| No units in answer | Rushing | Write 34 shells |
Quick check
- Ravi had 70 rupees, spent 25. How much left?
- Class 2A has 40 students, 2A has 35. How many more in 2A?
- Mum bought 90 eggs, used 45 for baking. Eggs left?
Stretch: Had 60 rupees, spent ₹15 on snacks, then ₹10 on stickers. How much is left? (Two steps.)
Revision tip: Draw a simple bar: total bar minus part sold equals part left — then write the subtraction sentence.
