3.  By the end of this lesson, you will be able to solve problems using a four-step plan.  Standard 4MR1.1 - Analyze problems by identifying relationships, distinguishing relevant from irrelevant information, sequencing and prioritizing information, and observing patterns.  Standard 4NS3.0 - Students solve problems involving addition, subtraction, multiplication, and division of whole numbers and understand the relationships among the operations.

4.  A roller coaster has 8 cars. Each car has 4 wheels. How many wheels are there in all on 2 roller coasters?  Thinking about what you know about problem- solving…  What strategy would you use to solve this problem?

5.  There are six girls in Daniella’s troop. They are planning a trip to the local amusement park. Admission for children is $12.  What is the total cost of admission for everyone to go?

6.  There are six girls in Daniella’s troop. They are planning a trip to the local amusement park. Admission for children is $12.  What is the total cost of admission for everyone to go?  Understand  What facts do you know?  There are 6 scouts that want to go.  The price of admission is $12 for each girl.  What do you need to find?  The total cost of admission for all girls.

7.  Plan  To find the total cost, you can use addition.  There are 6 girls, and it will cost $12 each.  So, add 12 six times.  What else could you do to save time?  There are six girls in Daniella’s troop. They are planning a trip to the local amusement park. Admission for children is $12.  What is the total cost of admission for everyone to go?

8.  There are six girls in Daniella’s troop. They are planning a trip to the local amusement park. Admission for children is $12.  What is the total cost of admission for everyone to go?  Solve  $12 + $12 + $12 + $12 + $12 + $12 + $12 = $72  Or 6 x $12 = $72  So, the troop needs $72 to go to the amusement park.

9.  There are six girls in Daniella’s troop. They are planning a trip to the local amusement park. Admission for children is $12.  What is the total cost of admission for everyone to go?  Look at the problem.  One way to check the answer is to use a drawing.  There are 6 x 12 or 72 squares, so the answer is correct.

10.  In the previous problem, the price for an adult admission was not included. Suppose the price of an adult ticket is $8 more than a child’s ticket. Find the total cost of three adult tickets. Explain.  If three adults were to go on the trip with the scouts, how much would admission cost for everyone to go?

11.  Using the textbook, please turn to page 27.  Do problems 5 – 11 on a lined piece of paper.  If you get them all correct, you will not have any Math problem solving homework from me!!  Good luck!!
