Introducing the Problem Set

Make photocopies of “Solve the Problem: Ticket Please” (page 33) and distribute to

students. Have students work in pairs, encouraging them to discuss strategies they

might use to solve the problem. You may want to walk around and listen in on some

of their discussions. After a few minutes, display the problem on the board (or on the

overhead if you made a transparency) and use the following questions to guide a

whole-class discussion on how to solve the problem:

What is the problem you have to solve? (Figure out the cost of the tickets.)

Look at the clues. How many different types of tickets are shown? (3)What are they?

(child, adult, and senior)

What does Clue 1 show? (The total cost of 3 senior tickets and a museum guide is $13.50.

The museum guide costs $4.50.)

What does Clue 2 show? (The total cost of 5 senior tickets is the same as the total cost of 3

adult tickets.) 31
