Everyone loves multiplying numbers 1-9 by 11 because of their fun, double-number patterns: 11, 22, 33, 44, 55, 66, 77, 88 and 99.

For two-digit numbers, add the first and second digits and place the answer between these. Example: 45 x 11 = ___.

· Four plus five is 9.

· Place 9 between 4 and 5.

· The answer is 495.

When the sum of the first and second digits is greater than 9, increase the left-hand number by 1. Example: 28 x 11 = ____.

· Add the first and second digits: 2 + 8 = 10.

· Add the 1 to the 2: 1 + 2 = 3.

· Place the 0 between 3 and 8.

· The answer is: 308.

By teaching children these fun, easy patterns, we will instill in them a love of numbers and fascination with math.
