About these worksheets
Multiplying a three-digit number by a single digit stretches the short algorithm to its limit: three multiplications, up to two carries, one written row. It cements fact fluency under load and is the natural bridge between 2×1-digit work and full 2×2-digit long multiplication.
Grade level: these worksheets are part of our 4th grade math worksheets collection.

Frequently asked questions
Where does this fit in the sequence?
After 2-digit × 1-digit is solid, before 2-digit × 2-digit long multiplication.
Do the problems include carrying?
Almost all of them. With a single-digit multiplier across three columns, most problems carry at least once.
How can a child check an answer?
Estimate first. 487 × 6 is a little less than 500 × 6 = 3,000, so the answer should be just under 3,000, and it is: 2,922. An answer far from the estimate usually means a carry was dropped or added twice.
