Jason Brambila, 14, hid under a bed and made a call to 911 when an intruder broke into his house while he was alone.
Kayla Boyd, 11, called 911 when her grandmother became unresponsive at home.
Kayla was able to give accurate information about her grandmother's health to a 911 operator.
"Just like Jason and Kayla, our children need to know how to call, when and when not to call, and remember not hang up until dispatcher lets them knows it's okay," said Jim Ritz, Berwyn Police Chief.
Friday's event also promoted a program called 911 for Kids.
One of its goals is to reduce unnecessary emergency calls.
