Adding and subtracting whole hundreds is mental math that comes from knowing what a hundred is. 300 + 400 is three hundreds and four hundreds, which is seven hundreds, or 700. 846 - 600 takes six hundreds away from eight hundreds and leaves two, with the 46 untouched, so the answer is 246. Second graders are expected to do this without regrouping or drawing blocks.
This worksheet gives twenty equations on one page, adding two whole hundreds or taking whole hundreds from a three-digit number, and a line for each answer. Ask your child to say the hundreds out loud, for example eight hundreds take away six hundreds, and then to read the whole number back aloud to check it.
Common Core standard: 2.NBT.B.8
300 + 400 is 3 hundreds and 4 hundreds, which is 7 hundreds: 700. 846 - 600 leaves 2 hundreds and keeps the 46: 246.
