Subtraction: 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

  • Print the stacked layout and ask students to write the problems from the sheet onto place-value mats before they solve them.
  • Build the check into the routine: after each answer, add the answer to the number taken away.
  • Mix this sheet with the addition one in the same lesson so students learn to read the sign.

Questions

Why can't I see any borrowing here?

Each problem is made so that no column borrows. The sheet is the first step; the next one in the set, Two-digit subtraction with regrouping, adds the harder cases.

Can I make a mixed sheet of both kinds?

Yes. Choose Subtraction in the maker, set the numbers to Within 100, and leave Regrouping on Some with, some without.

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

In each problem the digit in the ones place of the first number is at least as large as the digit being taken away, and so is the tens digit. Nothing needs to be traded. Students practice setting out the subtraction in columns, working from the ones, and writing a two-digit answer, which is the whole job at this stage.

Who it is for

Second grade, under Common Core 2.NBT.B.5. Use it before the regrouping sheet, or as a quick success sheet for students who have been struggling with borrowing and need to feel secure again.

Subtracting two-digit numbers where no column borrows · grade 2

A worked example

Take 78 − 34. Ones: 8 − 4 = 4. Tens: 7 − 3 = 4. The answer is 44. Then add 44 + 34 to see that it returns to 78, which shows students that subtraction can be checked with addition.

Mistakes to watch for

  • Subtracting the smaller digit from the larger whichever is on top, which gives a wrong answer once borrowing appears later. On these sheets it is hidden because it never matters.
  • Starting with the tens column and losing track of the place. Remind students to begin at the ones.
