How to do it
- Multiply by the ones, tens and hundreds digits, one row each.
- Add one more 0 for each new row.
- Add all three rows.
Teaching tip
Add the three rows one column at a time, starting on the right, just like regular addition. This sheet is aligned with Common Core 5.NBT.B.5.
About this worksheet
3-digit by 3-digit multiplication on graph paper, with shaded rows for the three partial products and the answer. Fewer has 4 problems, Standard has 6 and More has 9.
What kids practice
Fifth graders multiply bigger whole numbers with the standard algorithm, like 427 × 36 or 243 × 152. Each digit of the bottom number makes its own row, with a 0 for the tens row and two 0s for the hundreds row, and then the rows are added. The goal by the end of 5th grade is to do this accurately and without needing an area model, and to estimate to check that an answer makes sense.
Watch for
- Forgetting the 0 in the ones place for the tens row, or the two 0s for the hundreds row.
- Adding a carry from the first row into the second row.
- Lining up a row in the wrong columns.
- Adding the rows wrong after all the multiplying is right.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full multi-digit multiplication guide for 5th grade.
