       Do you know how to be a street smart? Being street smart means knowing how to keep yourself

safe from strangers when you're alone or with other kids.     1      

    Most strangers aren't dangerous and wouldn't do anything to hurt kids. Unfortunately, though. some

strangers can be dangerous, and it's impossible to tell who'ok and who's not.     2    That's why it's

important to follow these safety rules all the time:

    Make your whereabouts known.

    The adults who are taking care of you need to know where you are and when you'll be coming home.

idea, and traveling with a group of kids is even better.

    Safe spots are places where you can stop if you need help. Like the houses of kids you know, the

houses of your parents'friends, police stations, libraries, and fire departments. When you're walking or

riding your bike, make a mental note of the safe spots along your route. That way, you'll know where

they are in case you ever need one. 

        5    

    You're probably been told lots of times that you should not shout and keep quiet. But when you think

you might be in danger, it'a the perfect time to be noisy! If a stranger gets close to you, follows you or

tries to grab you, shout as loudly as you can and try to get away. People in the area will hear what's

going on and help you, so make plenty of noise.
