What you'll learn
- Match items that belong together: sock–shoe, pen–cap, bat–ball.
- Draw lines between pairs on worksheets.
- Explain why two items form a pair.
Key concepts
1. What is a pair?
Level 1 (Verbal): Two things that go together for use.
Level 2 (Symbolic): Functional match — one needs the other.
Visual: Column A to Column B line matching.
2. Not any two items
Verbal: Spoon pairs with bowl for eating soup — not with cricket bat.
Visual: Wrong pair crossed out.
3. One-to-one pairing
Each item matches exactly one partner in the exercise.
Worked example
Matching school things
Step 1 — Column A: sock, pencil, key. Column B: shoe, lock, eraser.
Step 2 — Sock → **shoe** (wear together).
Step 3 — Pencil → **eraser** (write and fix); Key → **lock** (open door).
Step 4 — Draw lines; no item left alone.
Answer: three correct pairs.
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Pair by colour only | Colour not always function | Ask: Do they work together? |
| One item to two partners | One-to-one rule | Each used once only |
| Random guessing | Skip reason | Say pair reason aloud |
Quick check
- What pairs with a shoe?
- Does a ball pair with a bat for cricket?
- Pair: diya — flame or water?
- Stretch: Make three new pairs from things in your bag.
Revision tip: Cover column B — guess partner from column A before revealing.
