Secure fluency in multiplication table facts, and corresponding division facts, through continued practice

What this means, in plain words

Times table facts are recalled from memory rather than counted out, which frees a child up to think about the problem itself.

Fluency means answering accurately and quickly enough that the number fact is no longer the hard part of the question.

This is data work: collecting information, showing it in a table or a chart, and reading answers back out of it.
