Adding within 100 is the heart of second grade arithmetic. This worksheet starts with the easier cases, where no ones add up to ten or more, so there is no regrouping. Some problems add two two-digit numbers, like 74 + 13. Some add a single digit, like 52 + 7. Some add a whole ten, like 36 + 40. The same idea works in every case: add the tens to the tens and the ones to the ones.
Children who see that can do all of these in their heads. Ask your child to say the parts out loud: 70 and 10 is 80, 4 and 3 is 7, so 74 + 13 is 87. Twenty problems on one page give plenty of practice, and none of the sums is 100 or more.
Common Core standard: 2.NBT.B.5
74 + 13: 70 + 10 = 80 and 4 + 3 = 7, so the sum is 87.
Adding the digits across, such as 7 + 4 + 1 + 3, instead of adding place by place.
Add the tens, then add the ones.
