I use this to generate the Nines Table for Multiplication.

I write the following on the board:

9 x 1 =

9 x 2 =

9 x 3 =

9 x 4 =

9 x 5 =

9 x 6 =

9 x 7 =

9 x 8 =

9 x 9 =

I tell the students that I have forgotten my nines table for multiplication.

I look at the nine problems on the board and I say, "Well, I know that 9 x 1 = 9,"

since any number times one equals that number.

So, I write 9 beside the first problem.

Now, I say, "Maybe it would help me if I counted the problems.

So, I write a 1 by 9 x 2 =,

Then I say and write a 2 by 9 x 3 = , etc,

so that my chart looks like this:

9 x 1 = 9

9 x 2 = 1

9 x 3 = 2

9 x 4 = 3

9 x 5 = 4

9 x 6 = 5

9 x 7 = 6

9 x 8 = 7

9 x 9 = 8

So I count again, this time starting at the bottom.

My chart now looks like this:

9 x 1 = 9

9 x 2 = 1 8

9 x 3 = 2 7

9 x 4 = 3 6

9 x 5 = 4 5

9 x 6 = 5 4

9 x 7 = 6 3

9 x 8 = 7 2

9 x 9 = 8 1
