Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Random order without logic | Must make sense | Ask: Can this happen before that? |
| Size order backwards without label | Say increasing or decreasing | Small to big = increasing |
| Two events same time slot confused | Pick reasonable order | Brush before or after breakfast — discuss standard routine |
Quick check
- What comes first: sleep or wake up?
- Order by height: ant, elephant, cat — small to big.
- First event in a cricket match: toss or six?
- Stretch: Order: monsoon rain, plant seed, mango ripe — explain.
