What this skill is

Facts with 10, 11, and 12.

When it comes up: Late third grade.

The mistake to watch for

Applying the 11s trick (11 × 3 = 33) past 9, so 11 × 12 gets written as 1112.

How to help

Show where the pattern breaks. A rule that stops working is worth understanding, not just memorizing.

Next: Division.

A worked example

Try 11 × 7. Multiply 10 × 7 = 70, then add one more 7: 70 + 7 = 77.
