Free printable 12 times table worksheets. Every fact from 12 x 0 to 12 x 12, printed both ways round, with an optional answer key.
The 12 times table is the 10s plus the 2s: 12 x 7 is 10 x 7 plus 2 x 7, so 70 + 14 = 84. Twelve turns up wherever things come in dozens, inches in a foot and months in a year, which is why many schools carry the tables on to 12.
Each sheet holds the whole table: 12 x 0 to 12 x 12 and the same facts turned around, twenty-five in all, each printed once and in a new order every time.

Split the 12 into 10 and 2. 12 x 8 is 10 x 8 = 80 plus 2 x 8 = 16, which makes 96.
Anywhere things come in twelves: eggs by the dozen, inches in a foot, months in a year, hours on a clock face. 3 feet is 36 inches because 12 x 3 is 36.
For most schools, yes. 12 x 12 = 144 is the largest fact on a standard multiplication chart. Beyond it, multiplication is done with the column method rather than recalled.
