    8 x 9 = 72
    9 x 9 = 81
    10 x 9 = 90

Have a look at these timesavers.

Look at the numbers on the right hand side. Can you see how the tens go up but the units go down?

- This is an easy one. All the digits in the 9 times table add up to 9.

    18 = 1 + 8 = 9
    27 = 2 + 7 = 9
    36 = 3 + 6 = 9

- What's 9 x 7 ? You can use the 9-method!
Hold out all 10 fingers, and lower the 7th finger.

There are 6 fingers to the left and 3 fingers on the right. The answer is 63.

- Try reversing the sum if you are having problems. 9 x 8 is the same as 8 x 9: 72.

- Look at the pattern below - can you see how the units column goes down one at a time and the tens column goes up?
You can also see how the 9 times table reverses itself!
