How it works
Every line on this 2 multiplication chart is a double: 2 × 7 = 14 is 7 + 7. The 2 times table runs from 2 × 1 = 2 to 2 × 12 = 24 here, or to 2 × 20 = 40 with Go up to × 20.

Every fact is a double
Multiplying by 2 is adding a number to itself, so 2 × 7 is 7 + 7 = 14. A pupil who knows the addition doubles to 10 + 10 already has 10 lines of this chart. Past 10, double the tens and the ones apart: 2 × 16 is 20 + 12 = 32.
Go up to × 20 for bigger doubles
Choose × 20 under Go up to and 8 more lines appear, 2 × 13 = 26 to 2 × 20 = 40. They train the split that doubles any number: for 2 × 47, double 40 is 80, double 7 is 14, and 80 + 14 = 94.
- Every other table's × 2 line is this chart turned around: 7 × 2 = 14 is 2 × 7 = 14.
- Double a 2s answer for the 4s, again for the 8s: 2 × 6 = 12, 4 × 6 = 24, 8 × 6 = 48.
- Halving undoes every line: 2 × 9 = 18 says half of 18 is 9, the division fact 18 ÷ 2 = 9.
Questions and answers
Is the 2 times table the same as counting by 2?
The answers are the same numbers, but the skill differs. Counting reaches 2 × 8 by saying eight numbers. A multiplication chart of 2 with its facts mixed up asks for 16 straight away. If the count is shaky, start with skip counting by 2.
Which numbers belong to the 2 times table?
Every even number does. Look at the last digit only: if it is 0, 2, 4, 6 or 8, the number is 2 times something. So 7,938 is in the table, because it ends in 8, and it is 2 × 3,969.
