For the first nine facts the eleven times table barely counts as work: 11, 22, 33, 44 — the digit simply repeats. That makes it the table children learn quickest and the one they are most likely to get wrong, because the repeating pattern stops at 11 x 9 and then 11 x 10, 11 x 11 and 11 x 12 give 110, 121 and 132. Those last three are the whole point of practicing this table, and these sheets weight the mixed-order pages accordingly rather than pretending the pattern continues.
Ordered sheets from 11 x 1 to 11 x 12 where the repeating-digit pattern is visible, mixed-order recall pages that give extra weight to the three facts past the pattern break, and missing-number rows in both directions. Division facts appear on the later sheets. One worksheet per US Letter page, black and white.
Because eleven is ten plus one, so multiplying by eleven is the same as adding a number to itself shifted one place left. For single-digit numbers there is nothing to carry, so 11 x 6 is 60 plus 6, which is 66. Once carrying starts, at 11 x 10 and beyond, the neat repeat stops.
What are 11 x 11 and 11 x 12?
121 and 132. These two are the ones children reliably miss, because the repeating-digit pattern has taught them to expect something else. Both are worth learning as standalone facts rather than as part of a sequence.
Is there a trick for multiplying two-digit numbers by 11?
There is: add the two digits and put the sum between them. 11 x 23 gives 2, then 2 plus 3 is 5, then 3, so 253. When the digit sum reaches ten or more you carry into the first digit, which is where most people go wrong, so it is worth practicing the carrying case deliberately.
Do schools still teach up to 12?
Practice varies by country and school. Where the twelve times table is expected, the eleven is usually taught alongside it, and both are commonly covered around ages 8 to 10 as an editorial guide.
