Here is the quickest and easiest way to memorise the 6 times table in just a few seconds. For this purpose, we have to make two (2) tic-tac-toe grids.

First, we will fill both grids with numbers from 1 to 9, leaving the number 0 outside the grid. Following the instructions, we would start from the bottom left-hand corner of each grid. To begin with, write 1, 2, 3 in the first column, 4, 5, 6 in the second one, and lastly, write 7, 8, and 9 in the third column. Moreover, write the number 0 outside the grid as instructed above. We would do the same for the second grid.

Moving forward, we would fill the first grid by dividing it into the top, middle and bottom rows. First, we would fill each column with numbers 0 in the first, 1 in the second, and 2 in the third row. Second, we would write 3 with the 0 written outside the grid. Continuing with the second grid, we would start from the top row again by filling it with numbers 3 in the first, 4 in the second, and 5 in the bottom row. Finally, we will write 6 with 0 to make it 60 outside the grid.

Next, we would draw a diamond shape in the first grid in such a way that 06, 12, 18, and 24 join each other at every corner, and then, we would extend a line from 24 at the bottom that straightly goes to 30 Similarly, we draw a similar diamond with an extended line on the second grid by joining 36, 42, 48, 54 and 60 with each other.

This is a hack for the 6 times table. The only thing left for you to do is to recite it loudly 3 to 4 times to learn it by heart.
