## HMH Into Math Grade 4 Module 1 Answer Key Place Value of Whole Numbers Musician
Each human culture has music, just as each has language. The Bureau of Labor Statistics summarizes that in 2016 there were over 170,000 jobs for musicians and singers in the United States alone. If you include people who play music just for fun, it is reasonable to assume there are millions of musicians in the world.

It is impossible to know exactly how many types of instruments there are, but experts believe the number to be in the thousands. You might already play, or be thinking about playing, an instrument. There is so much to decide! Which instrument will you choose? How much will you practice?

Work with a partner to gather information about sound. Cut a 4-foot piece of yarn. Tightly tie the handle of a metal spoon to the center of the yarn. Then wrap each end of the yarn around each of your index fingers. Hold your fingers against your ears. Have your partner tap the hanging spoon with a ruler. Try a larger spoon and other types of objects. Collect data about the sound of each object. What can you and your partner infer about sound?
