Why the 9 Times Table Seems Hard (But Isn't)
Many kids dread the 9 times table — the numbers look big and unfamiliar. But here's the secret: the 9s are packed with patterns that make them one of the most learnable tables of all. Once children discover these tricks, they often call the 9 times table their favorite.
The Famous Finger Trick
This is the most well-known shortcut for 9s, and it genuinely works for 9×1 through 9×10:
- Hold both hands out in front of you, palms facing down.
- Number your fingers 1 through 10 from left to right.
- To calculate 9 × 4, fold down your 4th finger.
- Count the fingers to the left of the folded finger: that's the tens digit (3).
- Count the fingers to the right of the folded finger: that's the units digit (6).
- Answer: 36. Every time, without fail.
This trick works for any multiplier from 1 to 10 and gives kids an instant confidence boost.
The Digit Sum Pattern
Every answer in the 9 times table has digits that add up to 9:
- 9 × 2 = 18 → 1 + 8 = 9
- 9 × 3 = 27 → 2 + 7 = 9
- 9 × 4 = 36 → 3 + 6 = 9
- 9 × 5 = 45 → 4 + 5 = 9
- 9 × 6 = 54 → 5 + 4 = 9
This pattern continues all the way to 9 × 10 = 90. Children can use this to check their own answers — a powerful self-correction tool.
The Tens-Minus-One Trick
Multiplying by 9 is the same as multiplying by 10 and then subtracting the number once:
- 9 × 7 = (10 × 7) − 7 = 70 − 7 = 63
- 9 × 8 = (10 × 8) − 8 = 80 − 8 = 72
- 9 × 9 = (10 × 9) − 9 = 90 − 9 = 81
This strategy connects to mental math skills children are already building and feels less like memorization and more like reasoning.
The Descending-Ascending Pattern
Look at the 9 times table written out and notice how the tens digits go up (0, 1, 2, 3…) while the units digits go down (9, 8, 7, 6…). Seeing the visual symmetry helps many children — especially visual learners — remember the sequence instinctively.
| Equation | Answer |
|---|---|
| 9 × 1 | 09 |
| 9 × 2 | 18 |
| 9 × 3 | 27 |
| 9 × 4 | 36 |
| 9 × 5 | 45 |
| 9 × 6 | 54 |
| 9 × 7 | 63 |
| 9 × 8 | 72 |
| 9 × 9 | 81 |
| 9 × 10 | 90 |
Putting It All Together
Teach one trick at a time and practice it for a few days before introducing the next. The finger trick is great for starters; the tens-minus-one method builds mental math strength. Combined, these tools give children multiple routes to the same answer — and that redundancy is exactly what makes facts stick for the long term.
