Multi-digit multiplication: 20 problems a sheet, 3 versions that do not repeat each other where the numbers allow.

How to use it

  1. Look at the sheet: it is a real, printable sheet. Switch between Sheet A, B and C, or press New numbers (N) for a fresh set.
  2. Change how many problems, how many versions, and whether the key prints. Settings stay in this browser; Share copies a link that rebuilds the same sheets.
  3. Press Print sheet A and key, or Print all. The answer key prints on its own page, so you can keep it back.

Ideas for class

  • Teach the area model first: draw 47 as 40 + 7, multiply each part by 6, and add 240 and 42. The written method is a short form of this.
  • Ask for an estimate before every third problem. It is the fastest way to catch a lost carry.
  • Use squared paper so digits stay in columns.

Questions

Does any problem have no carry?

A few do, such as 21 × 4, where no column goes over nine. Most need at least one carry, since the multiplier is up to 9 and the digits are random.

What is the next step after this?

Three-digit and four-digit numbers by one digit, then two-digit by two-digit. The maker has a level for each.

Are the answer keys checked?

Each answer is worked out by the code that wrote the problem, and our tests recompute every answer a second way and compare. Please still look over the key before you grade a class set.

What this worksheet covers

Multiplying a two-digit number by one digit is the first step from table facts to the written method. Every problem here has a two-digit number from 12 to 99 and a one-digit multiplier from 2 to 9. Stacked, they print with the line and space for the carried digit, so students practice both the facts and the place-value ideas that sit under the method.

Who it is for

Third and fourth grade. Common Core 4.NBT.B.5 asks students to multiply a whole number of up to four digits by a one-digit number. Students should be secure on their facts and on multiplying by multiples of ten before they start.

A worked example

47 × 6. Ones: 7 × 6 = 42, write 2 and carry 4. Tens: 4 × 6 = 24, plus the 4 carried is 28. The answer is 282. Estimate first: 47 is near 50, and 50 × 6 = 300, so the answer should be a little under 300.

Mistakes to watch for

  • Forgetting to add the carried digit, so 47 × 6 comes out as 252 instead of 282. An estimate catches it.
  • Multiplying only the ones and copying the tens. Stress that the multiplier applies to both digits.
