The 11 times table
For 11 × 1 to 11 × 9, the answer has the same digit twice: 11 × 7 = 77.
For 11 × 10, 11 × 11 and 11 × 12, use 10 times the number plus the number once more: 11 × 12 = 120 + 12 = 132.
Key ideas
- The digit is written twice for 11 × 1 to 11 × 9.
- For 10, 11 and 12, add the number to 10 times the number.
- Check with the division: total ÷ 11.
Method. Write the digit twice. This works for 11 times 1 to 11 times 9.
- Write the number twice. In the 11 times table, a one-digit answer has the same digit twice.7 and 7
- Read the two digits as one number. Put them side by side.77 = 77
- Write the answer. This is 11 groups of the number.77
Check. Check: 77 ÷ 11 = 7.
Watch out. The pattern works for 1 to 9. For 10 to 12, use 10 times the number plus the number.
Method. Use 10 times the number, then add the number once more.
- Work out 10 × 12. Multiplying by 10 adds a zero.10 × 12 = 120
- Add one more 12. There is one group of 11 for each 10 and 1.120 + 12 = 132
- Write the answer. This is the total.132
Check. Check: 132 ÷ 11 = 12.
Watch out. Do not write the digit twice for 10, 11 and 12; the pattern is different.
Method. Count in 11s to find 4 groups of 11. The order of the numbers does not matter.
- Count in 11s, 4 times. Each count adds one more group of 11.11, 22, 33, 44
- The last number we said is the answer. We counted 4 groups of 11.11 × 4 = 44
- Write the answer. The order of the two numbers does not change the answer.44
Check. Check: 4 × 11 is also 44.
Watch out. Learn the 11 times table in order, then say it in any order.
Watch out
Watch out. The pattern stops at 9. 11 × 10 is 110, not 1010 and not 100.
Exam tip
Grown-up tip. Ask the child to say the pattern for 11 × 3, then for 11 × 12, and to notice the difference.
