click fraud protection

We are reaching one of the last multiplication tables. Remember that it is very important that when your children learn a table and start another they NEVER have to stop reviewing the one they already know. Memorizing them is not enough to internalize them so it is very important to continue practicing them all in an orderly and disorderly way.

In this video I will explain the 9 table, one of the ones I like the most because it also has trick. In fact, it has three tricks:

Tip 1: If you know the other tables without realizing it, you will have already learned the 9 table. You ask, how? Well, very easy! If you look at the table of 9 it is formed by the penultimate of the multiplications of the other tables. 1 x 9, 2 x 9, 3 x 9, 4 x 9... is the same as 9 x 1, 9 x 2, 9 x 3, 9 x 4 ...

Tip 2: This trick is very curious because to know the results of the 9 table you have to imagine two imaginary rows. In the left row you will write the numbers from 0 to 9 in order and in the right row from 9 to 0. By joining these numbers you will get the results of the 9 table.
