Multiplication Practice 3 - 3-Digit Times 1-Digit

💡Tips for Parents

▸ Why It Matters This sheet jumps from 2-digit to 3-digit numbers, and seven of the ten problems — including 318 × 5, 256 × 7, and 327 × 8 — produce four-digit answers, so your child now has to carry through three place-value columns in a row instead of just two. The three remaining problems, 123 × 4, 215 × 3, and 142 × 6, stay at three digits, so your child can't assume every answer automatically gains an extra digit — each problem has to be judged on its own. ▸ Getting Started Work strictly right to left — ones, then tens, then hundreds — and have your child write each small carry number above the column it belongs to before moving on, so a carry from the ones place doesn't get confused with one from the tens place two steps later. Before solving, a quick estimate helps: rounding 318 to 300 and multiplying by 5 gives 1,500, so an answer far off signals a mistake worth rechecking. If column multiplication feels shaky, try expanded form as a backup: for 142 × 6, multiply 100 × 6, 40 × 6, and 2 × 6 separately (600, 240, 12) and add them to confirm the same 852. ▸ If They Get Stuck If the answer comes out as three digits when it should be four (like on 256 × 7), a carry was likely dropped in the hundreds step — have your child re-multiply just the hundreds digit and check whether a carry from the tens column should have been added in. If a four-digit answer appears where a three-digit one was expected, check the opposite mistake: an extra carry added where none was needed. Another common slip is writing the full two-digit result of a step, like "24," into one box instead of writing "4" and carrying the "2" — walking through a problem together at the board usually clears this up. ▸ Praise Points Praise your child for getting a problem like 256 × 7 = 1792 right, where the answer gains an extra digit — recognizing that a product can grow beyond the number of digits it started with is a real leap in place-value understanding. Correctly telling apart the three-digit answers (123 × 4, 215 × 3, 142 × 6) from the four-digit ones across all ten problems, rather than defaulting to one pattern, shows they're reasoning through each one individually. It's also worth celebrating when your child catches their own mistake using the estimate-first habit — that self-checking instinct carries them through harder multiplication later.

🎯What This Worksheet Builds

This worksheet extends the column-multiplication method from 2-digit to 3-digit numbers multiplied by a single digit, requiring the child to align and carry across three place-value columns — ones, tens, and hundreds — instead of just two. Across the ten problems, seven (318×5, 256×7, 184×9, 327×8, 245×6, 163×7, 298×4) produce four-digit answers, while three (123×4, 215×3, 142×6) stay at three digits, so the child must evaluate each product individually rather than assume a fixed digit-count pattern applies throughout.

👉Next Step

For the next challenge, move on to multiplying a 2-digit number by a 2-digit number, such as 34 × 12, which introduces a second partial-product row — one for the ones digit of the multiplier and one for the tens digit — that must be shifted one place to the left and added to the first row before arriving at the final answer, adding a new layer of place-value tracking beyond simple carrying.
