Free 2nd Grade Math Games
Second grade is when arithmetic starts to feel like arithmetic. Second graders extend their fluency with addition and subtraction to within 100, working with regrouping (borrowing and carrying) for the first time. They also deepen their place-value understanding through three digits and get their first structured exposure to multiplication as repeated addition. This free worksheet generator is preset to medium addition (1–100), which matches the second-grade target in the Common Core 2.NBT standards. After fluency builds, switch to subtraction at medium, and preview multiplication at easy as the year progresses. Ten to fifteen minutes of daily practice is the sweet spot.
How to use these 2nd grade math worksheets
Start with addition, medium
Medium is 1–100, the second-grade target range. Some of these problems require regrouping.
Rotate in subtraction
Two-digit subtraction with regrouping is the harder cousin of addition. Practice it every few sessions.
Preview multiplication at easy
Second graders are introduced to multiplication as repeated addition. Easy multiplication (1–10) is a gentle preview.

Frequently asked questions
What math do second graders learn?
Second grade Common Core standards cover addition and subtraction within 100 on paper (with regrouping), within 20 from memory, place value to 1,000, money and time, measurement in inches and centimeters, and the foundations of multiplication and division as repeated addition and sharing. Word problems become a regular feature.
What is regrouping and how do I explain it?
Regrouping is what you do when you add or subtract two-digit numbers and the ones place overflows or needs to borrow. For example, 47 + 28 — the ones digits sum to 15, so you 'carry' the 1 to the tens place. The best way to explain it is with base-10 blocks: physically group ten ones into a single ten.
When should second graders start memorizing times tables?
Times-table memorization formally starts in third grade, but some second-grade curricula introduce the 2s, 5s, and 10s because they have simple patterns. If your child is ready and interested, preview them — if not, wait until third grade.
How long should a 2nd grader practice math daily?
Ten to fifteen minutes of focused practice at home, on top of school work. Quality is more important than quantity. One clean sheet a day builds more than three rushed ones.
My second grader is still slow with sums within 20. Is that a problem?
By the end of second grade, Common Core expects fluent addition and subtraction within 20 from memory. If your child is still counting on fingers for 7 + 8 at the end of the year, it's worth targeted practice to shore it up before third grade, where the pace increases.
