For this activity, you'll take on the role of an inspector. You'll check whether the quotient, or answer for a division problem, is correct or not. You'll practice multiplying a given two-digit quotient times a single-digit divisor. You'll also check the answer by multiplying a one-digit quotient times a two-digit divisor.
Don't forget to add the remainder to the product of the quotient and divisor.
Before you begin, get a piece of paper, a marker, scissors, and glue. Cut the paper into 10 strips. Then write the word "Correct" on 5 strips and the word "Wrong" on another 5 strips. Next, copy the five division solutions below to another piece of paper. As an inspector, you'll check whether each of the quotients to the division problems below is correct or not. If it's correct, paste a "Correct" strip beside the problem and the answer. If the answer is wrong, paste a "Wrong" strip.
1.)
2.)
3.)
4.)
5.)
You can prove that the answer is correct or wrong by solving each problem on your own. Let's try the first problem:
1.)
The problem shows that 253 divided by 8 equals 31 with a remainder of 5 (253 ÷ 8 = 31 + R5). Is the answer correct? It's correct. So let's paste a "Correct" strip beside the problem. Here's how it will look on your paper:
Correct
Then prove that it's correct by solving it on your own. First, we multiply 31 times 8 and get 248 (31 x 8 = 248). We write our answer below 253.
Now we subtract to find the remainder. It's 5! So the answer is correct. It's your turn to inspect the remaining problems.
