About 2-Digit by 1-Digit Multiplication Worksheets
Grade 4 — and this is one of the cleanest cross-jurisdiction alignments of the math cluster. US (CCSS 4.NBT.B.5): multiply up to four-digit by one-digit, plus two two-digit numbers — Grade 4. Ontario 2020 (4.B2.5): 'Represent and solve problems involving multiplication of two- or three-digit whole numbers by one-digit whole numbers and by 10, 100, and 1000' — Grade 4.

Free printable 2-digit by 1-digit multiplication worksheets for parents, teachers, and homeschoolers — Grade 4 (CCSS 4.NBT.B.5). Standard algorithm format, 3-digit option, answer key included.
How to use
- Pick problem type. '2-digit × 1-digit' (default) is the Grade 4 introduction format (e.g., 47 × 6, 89 × 4). '3-digit × 1-digit' extends to larger numbers (234 × 7). 'Mixed' randomizes both — use this once students are comfortable with both formats individually.
- Choose problem count. 12 (default) gives the most workspace per problem — best when students are first learning the algorithm. 20 is compact but still workable. 30 is drill-only for students who've internalized the algorithm and just need speed practice.
- Vertical layout is the only option here — it's the only correct format for the standard algorithm. The bottom number sits below the top with the multiplication sign on the left and a horizontal bar above the answer space.
- Use the seed to share. The 6-character seed in the footer ensures matching problems across student copies and the answer key.
- Three print buttons — Print Problems for student copies (with workspace below each problem), Print Answer Key for the teacher's grading sheet, Print Both for parent / homeschool one-job convenience.
Frequently asked questions
What grade level are these worksheets for?
Grade 4 — and this is one of the cleanest cross-jurisdiction alignments of the math cluster. US (CCSS 4.NBT.B.5): multiply up to four-digit by one-digit, plus two two-digit numbers — Grade 4. Ontario 2020 (4.B2.5): 'Represent and solve problems involving multiplication of two- or three-digit whole numbers by one-digit whole numbers and by 10, 100, and 1000' — Grade 4. WNCP provinces (Alberta, BC, Saskatchewan, Manitoba, Atlantic): 4.N.4 covers written 2-digit × 1-digit multiplication — Grade 4. Quebec PFEQ Cycle 2: conventional 3-digit × 1-digit process by end of Grade 4. Grade 4 students typically meet 2-digit × 1-digit first (September-October), extend to 3-digit × 1-digit by November, and move into 2-digit × 2-digit by mid-year. Grade 5 students use these for review when working on multi-digit decimals.
What's the standard algorithm for multi-digit multiplication?
The standard algorithm is the column-stacked method most adults learned: write the larger number on top, the smaller below, multiplication sign on the left, horizontal bar above the answer space. Multiply the bottom number by each top digit, working right-to-left, carrying as needed. For 47 × 6: 6 × 7 = 42 (write 2, carry 4), 6 × 4 = 24 + 4 carried = 28 (write 28). Final answer: 282. The vertical layout in this worksheet is what students need to practice this method correctly.
Should I use 2-digit, 3-digit, or mixed?
Start with 2-digit × 1-digit only for the first 2-3 weeks of teaching the standard algorithm — it's the easiest entry. Move to 3-digit × 1-digit once students can do 2-digit fluently (the algorithm is identical, just one more digit). Use Mixed once both feel solid — it builds the flexibility students need for word problems and standardized tests where problem size varies.
What about 2-digit by 2-digit multiplication?
That's a separate tool we're building (the algorithm involves partial products lined up across two rows, which is structurally different from single-digit multiplier). Coming soon. For now, this tool covers the introductory phase — once students master 2-digit × 1-digit and 3-digit × 1-digit, the 2-digit × 2-digit algorithm builds on the same foundation.
