CCSS.MATH.CONTENT.4.NBT.B.5 — 4.NBT.B.5, in the Number & Operations in Base Ten domain for Grade 4. The published standard reads: “Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations.” The worksheet assesses that standard rather than a paraphrase of it.
