Use ten groups and one more
Eleven groups are ten groups plus one. For eleven groups of twelve, add twelve to one hundred and twenty. This method works beyond the repeated-digit answers at the start of the table.
11 × 12 = 10 × 12 + 12 = 120 + 12 = 132
The complete table
| Fact | Answer |
|---|---|
| 11 × 1 | 11 |
| 11 × 2 | 22 |
| 11 × 3 | 33 |
| 11 × 4 | 44 |
| 11 × 5 | 55 |
| 11 × 6 | 66 |
| 11 × 7 | 77 |
| 11 × 8 | 88 |
| 11 × 9 | 99 |
| 11 × 10 | 110 |
| 11 × 11 | 121 |
| 11 × 12 | 132 |
Check your reasoning
Writing a digit twice works for 11 × 1 through 11 × 9, but 11 × 12 is 132. Use ten groups plus one to check larger facts.
Neighbouring facts differ by 11. If you know 11 × 6 = 66, add 11 to find 11 × 7: 66 + 11 = 77.
Try it yourself
Say or write an answer before opening each question. If you get stuck, use the method above, then try that fact again later without looking.
11 × 3 = ?
11 × 3 = 33. Reversing the factors gives 3 × 11 = 33 too.
11 × 7 = ?
11 × 7 = 77. Reversing the factors gives 7 × 11 = 77 too.
11 × 8 = ?
11 × 8 = 88. Reversing the factors gives 8 × 11 = 88 too.
11 × 11 = ?
11 × 11 = 121. Reversing the factors gives 11 × 11 = 121 too.
11 × 12 = ?
11 × 12 = 132. Reversing the factors gives 12 × 11 = 132 too.
Connect the tables
Compare the 10 times table and look for doubles or groups you can add. In the multiplication chart, follow the whole row and its matching column.
