• Paper
• Pencil
• Calculator (optional)

No specific prior knowledge is required for this lesson.

Activities

1. Activity 1: Counting the Songs

   Listen to the Mama Mia soundtrack or search for the song list online. Count the total number of songs in the musical. Write down the number.

2. Activity 2: Calculating Running Time

   Research the average duration of a song in Mama Mia. Multiply the average duration by the total number of songs to calculate the approximate running time of the musical. Show your calculations.

3. Activity 3: Ticket Sales Revenue

   Find the average ticket price for a Mama Mia show. Multiply the average ticket price by the seating capacity of the theater to estimate the potential revenue from a sold-out performance. Use your calculator if needed.
