11. 5 425 3 522 Solution: 85 Solution: 174 Please pick up all 3 papers on the warm-up table. Then, find the quotient of the following two problems.

12.  Algorithm  a specific set of instructions for carrying out a procedure or solving a problem  Method, procedure, technique Now you can sound super smart! :)

14.  In long division, there are three steps that you keep doing until you reach your goal! Divide Multiply Subtract Bring it Down Zero after subtraction and no number to bring down!

15.  Think of it as an 18-wheeler truck. You are the driver and know how many boxes the company needs delivered. In the back are all of your supplies that haven’t been placed in boxes yet.

16.  You need to deliver 3654 boxes of Girl Scout cookies. You have been able to find 42 large cardboard boxes to put the cookies in. How many boxes of cookies can go in each cardboard box? 42 3654 Step one: How many times does 42 go into 365? (Divide) Strategy: Guess and Check 42 5 = 210 (way too small) 42 9 = 378 (over!) 42 8 = 336 (Oh YEAH!)

17. 42 3654 8 -336 294 Step two: Place the 8 above the final place value of the 365. Multiply 8 and 42 to get 336. Step three: Subtract 336 from 365. Strategy: Guess and Check 42 5 = 210 (way too small) 42 7 = 294 (Perfect!) 7 -294 0 Complete Answer You can put 87 boxes of Girl Scout cookies in each cardboard box. Step four: Bring down the 4

18.  Remainder: is what fraction of the whole is going to be left over.  You are buying a game with your 4 friends that costs $28. How much does each person owe? How do you set up this problem?

19.  Instead of using a R remainder, just keep dividing and form a decimal. 5 28 5 -25 3 R3 5 28 -25 3 5.0.0 0.6 -30 0 THEN NOW

20. 16452 -32 Strategy: Guess and Check 16 2 = 32 16 3 = 48 132 2 -128 8 Strategy: Guess and Check 16 9 = 144 16 8 = 128 4.0 0 -32 -80 8 0 0 0.2 5 Strategy: Guess and Check 16 5 = 80

21.  Our class with 28 people wants to go on a trip to the aquarium. They gave us a group rate of $595 for everyone. How much does each student have to pay?  My 3 roommates and I want to buy new living room furniture. We found some that costs $2499. How much would each of us have to pay? Each student in the class would pay $21.25. Each roommate would have to pay $624.75.

22.  Find the quotient! 41 87248 24 2328 Solution: 2,128 Solution: 97

23.  Sarah’s annual salary is $65,013. If she works all 52 weeks of the year, how much is she paid each week?  The distance from New York to Tokyo is 6,375 miles. If it takes 15 hours to fly from NY to Tokyo, how many miles per hour is the plane flying? Sarah makes $1250.25 per week. The plane flies at 425 miles per hour.

24.  In 2012, Taylor Swift’s concert tour grossed approximately $26,310,144 over her 21 shows. How much money did each concert make on average? Taylor Swift’s concerts made $1,252,864 on average.

25.  MAKE SURE TO PICK UP THE NOTETAKING SHEET AND HOMEWORK FROM THE BACK TABLE!!  Last year, Abby made $33,300. How much money did Abby make each month? Abby made $2775 per month.

26.  The key is ESTIMATION!!!  Estimation helps you make sure that your answer makes sense. 242÷2.2= ? 240÷2= 120  Now make sure that your answer is reasonably close to the estimation.

27. 1) You cannot have any decimals on the outside of the division sign, so you have to move the decimal. 2.2 242 0 Move the decimal until it is a whole number! Then move the decimal the same amount of spaces on the number under the division sign. Place a 0 in each place value where you moved the decimal

28. 2) Use the standard division algorithm. 22 2420 -22 1 2 01 2 00 0 - 0

29. 3) Check and make sure your answer is reasonable. Estimate 240÷2= 120 Exact Answer 242÷2.2= 110 It looks very reasonable! This step helps see if you got your decimals in the right place.

30. 12 50.28.425.124 12.24.19

31.  There is only one difference between multiplying whole numbers and decimals… You have to remember to move the decimal once you get the answer!!! So for your last step, you have to do the DECIMAL DANCE!

32. 3.456 x 1.3 1) Estimate! 3 1 = 3 2) Use your imagination and pretend the decimals aren’t there 3) Use the standard multiplication algorithm 4) Count the number of digits located to the right of the decimal 5) Do the Decimal Dance! 10368 3456 0 + 44928.

33. 10.47 X.92 65.2 x.245 9.632415.974

34.  Sawyer is saving $6.35 a week to buy a video game that costs $57.15. How many weeks will he have to save to buy the video game? Sawyer will have to save for 9 weeks to afford the video game.
