Math Worksheets for 2nd Graders Second Grade Math Worksheets: Addition & Subtraction to 100, Place Value to 1,000 & Word Problems

➕ Addition to 100

Twelve two-digit addition problems, and every single one regroups — that is the point of the sheet. Adding the ones makes 10 or more each time, so your child practices the full move: add the ones, carry the ten into the little box, then add the tens. The box is printed above every problem because second graders who write the carried ten down stop forgetting it — and forgetting it is the number-one error at this level.

➖ Subtraction to 100

Twelve two-digit subtraction problems, each one built so the top ones digit is too small — borrowing is required every time. Your child practices the whole exchange: spot that the ones can't be done, trade one ten from the tens column, then subtract. It is the mirror image of carrying, and it clicks fastest when the two sheets live side by side in the same week.

🔀 Mixed Addition & Subtraction

Twenty problems to 100 that alternate between addition and subtraction without warning, just like real math. One problem wants carrying, the next wants borrowing, and the only way to know is to read the sign first — the habit this sheet exists to build. Expect the first run to be slow. The pause before each problem is the skill forming.

🔟 Place Value to 1,000

Twenty items stretch place value into the hundreds, in both directions. Half build a number from its parts — 6 hundreds + 2 tens + 3 ones = ___ — and half take one apart into expanded form: 828 = 800 + ___ + ___. A child who can move both ways owns the idea that makes three-digit addition next year feel like a small step instead of a cliff.

📖 Word Problems

Six stories with second-grade numbers: crayons gained by the handful, birds leaving a park, a hundred-page book with pages still to read. Four ask one clear question; two hide a second step inside — bake, bake more, then sell some — for kids ready to hold two moves in mind. Each story leaves room to write the number sentence before the answer, the habit that keeps story problems from becoming guessing games.

🖨️ How to Use These Worksheets

1. One sheet a day is a full session. Twelve to twenty problems of two-digit work is real effort for a seven-year-old. Little and often builds the regrouping habit; a big stack builds resistance.
2. Say the move out loud. “Ones first. Too big? Carry. Too small? Borrow.” Narrating the steps feels silly for a day and then quietly becomes how they think — most regrouping errors are skipped steps, not weak math.
3. Base-ten blocks are allowed. Counters, drawn tens sticks, real coins — second graders are meant to model with them. A child who can show 47 + 38 with blocks understands the carried ten; the pencil work is just the shorthand.
4. Check together and ask how. A correct answer with a shaky method and a wrong answer with a good method are both useful information. Ask, don't just mark.

📈 Grade Level Is a Guide, Not a Gate

Worksheets are labeled by grade, but children are not, and the label matters less than the fit. If the to-100 sheets still feel big, there is no penalty for dropping back: our first grade math worksheets firm up addition and subtraction within 20, and a confident week there makes this page easier, not later. The reverse is true too — a second grader who flies through all five sheets is telling you they are ready for three-digit numbers and the first taste of multiplication. The path is a staircase, not a schedule, and standing on a step until it feels solid is how the next one gets climbed.

⏱️ Fluency Without the Stopwatch

Nothing on these pages is timed, and that is a choice. By second grade the to-20 facts should be getting automatic — working memory spent recalling 8 + 7 is working memory not spent on the carrying. The strategies that got them there still count, and two-digit work adds one more: add the tens, then the ones. A child who owns the strategies gets fast on their own. Racing a timer before the strategies exist teaches guessing; building them first makes the timer unnecessary.
