In 156 ÷ 3, the first 15 tens divided by 3 give 5 tens in the quotient. Then 6 ones divided by 3 give 2 ones.
In 156 ÷ 3, the first 15 tens divided by 3 give 5 tens in the quotient. Then 6 ones divided by 3 give 2 ones. The answer is 52; 52 × 3 = 156 checks it.
At each stage, divide, multiply to check that part, subtract and bring down the next digit when needed. Keep any necessary zeros in the quotient. With a remainder, check dividend = divisor × quotient + remainder.
Work through one example aloud before independent practice. To check 18 + 7 = 25, calculate 25 − 7. If a word problem asks about meters or coins, include that unit and check whether the answer fits the situation.
