Welcome to Grade 3 addition! Let's solve forty-five plus thirty-two. First, we add the ones place: five plus two equals seven. Then we add the tens place: four plus three equals seven. So our answer is seventy-seven.
Now let's try a harder problem: one hundred seventy-eight plus two hundred fifty-six. First, add the ones: eight plus six equals fourteen. We write down four and carry one to the tens place. Next, add the tens: one plus seven plus five equals thirteen. We write down three and carry one to the hundreds place. Finally, add the hundreds: one plus one plus two equals four. Our answer is four hundred thirty-four.
Now let's solve a word problem. A baker made one hundred fifty cookies on Monday and two hundred thirty-five cookies on Tuesday. How many cookies did the baker make in total? First, we identify the numbers: one hundred fifty and two hundred thirty-five. Then we add them: zero plus five equals five in the ones place, five plus three equals eight in the tens place, and one plus two equals three in the hundreds place. The baker made three hundred eighty-five cookies in total.
Let's practice with more addition problems! First, sixty-seven plus twenty-eight equals ninety-five. Next, one hundred forty-nine plus one hundred eighty-six equals three hundred thirty-five. Remember to carry the one! Finally, two hundred thirty-four plus eighty-nine equals three hundred twenty-three. Great job! Remember these tips: always start with the ones place, carry when needed, and check your work.
