How to Help Your Child Remember Nine Times Table

One of my Favourite Amazing Properties of Nine

Learning the Times tables can be a very daunting time for parents and children alike. Parents are forever pulling their hair out over all of the hassle and pain that comes with getting their child to know, memorise and understand the multiplication times table. In my experience in education, I have so many of my favourite tricks to help children learn the times table easily. One such one is a special way to look at the 9 Times table, which is such fun when practised with your child.

Take a look at the 9 Timestable when it is written down:

9 * 1 = 9

9 * 2 = 18

Notice that the numbers in the results add up to nine as in:

9 * 2 = 18 (1+8 =9)

One and eight add up to nine. 9 times two is 18, and the digits in 18 add up to nine.

What about the next one?

9*3 = 27 (2+7 = 9)

Two and seven add up to nine.

9*4 = 36 (3+6 = 9)

Three and six add up to nine.

9*5 = 45 (4+5 = 9)

Four and five add up to nine.

9*6 = 54 (5+4 = 9)

Five and four add up to nine. 9 times six is 54, and the digits add up to nine.

9*7 = 63 (6+3 = 9)

Six and three add up to nine.

9*8 = 72 (7+2 = 9)

Seven and two add up to nine.

9*9 = 81 (8+1 = 9)

Eight and one add up to nine.

9*10 = 90 (9+0 = 9)

Nine and zero add up to nine.

9*11 = 99

The only digits that don’t add up to 9 are the two digits in 99 as 9 + 9 = 18, but it is easy to remember that 9 * 11 is 99. Double 9.

9*12 = 108

One and zero and eight add up to nine.

Isn’t the Nine Times Table amazing?
