Divide by 1 Digit Divisors Lesson 2.2 Homework can refer to the Go Math 5th Grade Lesson 2.2 Divide 1-Digit Divisors. This one address the essential question of how do you solve and check division problems. There is a tutorial video on Youtube shared by Anthony Waara that breaks down the important steps of what it means to divide. Below is the summary as explained on the video.
Unlock the Problem:
Jenna’s family is planning a trip to Oceanside, California. They will begin their trip in Scranton, Pennsylvania, and will travel 2,754 miles over 9 days. If the family travels an equal number of miles every day, how far will they travel each day?
Note:
- Underline the sentence that tells you what you are trying to find.
- Circle the numbers you need to use.
Answer:
The one that should be underlined is “equal number of miles every day”.
The ones that should be circled are 2,754 miles and 9 days. Keep in mind that 2,754 is the dividend while the divisor is 9 days.
Step 1:
Use an estimate to place the first digit in the quotient.
Estimate. 2,700 + 9 = 300
The first digit of the quotient is in the hundred’s place.
Step 2:
Divide the hundreds
Step 3:
Divide the tens
Step 4:
Divide the ones
2,754 : 9 = 3066
276 (hundreds)
05 and 00 (tens)
54 and 54 (ones)
Since 3066 is close to the estimate of 300 the answer is reasonable. So, Jenna’s family will travel 306 miles a day.
For your information, division and multiplication are inverse operations. They are the opposite operations that undo each other. Feel free to use multiplication if you want to check your answer to a division problem. Here is the instance to divide and check your answer:
In order to check your answer to a division problem, you will need to multiply the quotient by the divisor. If a remainder does exist, you can add it to the product. In the end, the result should equal the dividend.
6614 : 6 = 102 r2
102 is the quotient, 66 is the divisor, 2 is the remainder is 614.
The second example is 441 : 7, which is 63.
N = 7 x 63
N is the dividend, 7 is the divisor, and 63 is the quotient. By multiplying the divisor and the quotient, the result will be 441.
The third example is 752 : 6. The answer to the question is 125 r. 752 is the dividend, 66 is the divisor, 125 is the quotient, and n is the remainder. By multiplying the divisor and the quotient, the final result will be 125 r.
The explanation above might confuse you. If it is the case, you are recommended to watch the video by Anthony Waara on Youtube.
