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.

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?

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?

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.

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?

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!!
