In Grade 2, you add and subtract 3-digit numbers all the way up to 1000. The smart way is to stack numbers by place value so hundreds sit under hundreds, tens under tens, and ones under ones. Think of 132 + 245 as (100 + 200) + (30 + 40) + (2 + 5), which equals 300 + 70 + 7, or 377. When the ones or tens add to more than 9, you carry a new ten or hundred to the next column. For a problem like 456 - 128, the ones column 6 - 8 does not work, so you borrow a ten from the tens place to make 16 - 8 = 8. Word problems in Grade 2 use these same steps in real situations like pages read, books collected, or coins saved. In Grade 3, you will keep these ideas and use them for multi-digit multiplication and long division, so mastering place-value strategies now makes later math much easier.

Common Mistakes to Watch For
- Forgetting to carry a 1 to the next column when ones or tens add to more than 9, which leaves the sum 10 or 100 too small and makes the answer wrong.
- Subtracting the smaller digit from the larger digit no matter where it sits, instead of borrowing from the next place when the top digit is smaller.
- Misaligning the digits so hundreds, tens, and ones are not stacked under each other, which mixes up the place values and gives a very wrong total.
Frequently Asked Questions
What does regrouping mean in Grade 2 addition?
Regrouping means trading 10 ones for 1 ten, or 10 tens for 1 hundred, when a column adds to more than 9. You write the extra digit above the next column and add it in.
How do I know when to borrow in subtraction?
You borrow when the top digit is smaller than the bottom digit in a column. Take 1 from the next place to the left, turn it into 10, and add it to the top digit before subtracting.
Can I check my answer a different way?
Yes. Add the answer to the number you subtracted and you should get the starting number. For addition, switch the two numbers and add again to make sure you get the same total.
What if I only need to add the hundreds?
Sometimes you can use place-value shortcuts. For 300 + 400, just add the hundreds to get 700. This works because the tens and ones are zero, so no regrouping is needed.
Do word problems use the same steps?
Yes. Read the problem, pick add or subtract, stack the numbers by place value, and solve. Many Grade 2 word problems need two steps, so add first and then subtract, or the other way around.
