Whole hundreds add like ones: 3 + 2 = 5, so 300 + 200 = 500. Seeing the pattern lets kids add large numbers in their heads.

Add Whole Hundreds: how to help at home or in class
Draw squares on paper where each square stands for one hundred, then make groups of two or three and count them together. Ask your child to say the answer in hundreds before writing the number, so "eight hundreds" turns into 800. Finish by asking how many hundreds make 1,000; the answer is ten. When they say that without hesitating and write the right number of zeros, they can move on to adding a one-digit number to a three-digit number.
