Who it is for

The 1 to 20 chart is not a learning tool for the basic facts; the 1 to 12 chart does that job with bigger type. This one suits a 4th to 6th grader who is multiplying two-digit numbers, checking long division, or working with factors and multiples, and wants to confirm 17 times 13 without a calculator. It also answers the question children ask once they know the small table: what happens past 12.

The type is smaller to fit 21 columns on a Letter page, so print it for a desk or a binder rather than the wall. The square numbers from 1 to 400 run down the diagonal, shaded by default.

Patterns worth pointing out

The 11 row is the easy one up to 99 and then turns into a two-step fact; the 15 row ends in 5 or 0 and climbs by 15; the 19 row is one less than 20 times the number, which is a mental trick worth teaching from the chart. Cover the right half and ask the child to predict a cell before uncovering it.

Common questions

Is there a 1 to 100 multiplication chart?
A 100 by 100 grid has 10,000 cells and does not fit on a page you can read. The 1 to 20 chart is the largest that prints legibly on one sheet; for bigger products, the standard algorithm is the tool.
Which chart does a 3rd grader need?
The 1 to 12 chart on the main multiplication chart page. Third grade standards stop at the products of one-digit numbers.
