May I go to the bathroom?
I may hang out with my friends tonight
She may dance like Shakira
We may travel to Europe in vacations
They may visit their parents tomorrow

I can swim since i am five years old
They can skate very well
We can go to the movies after school
She can't speak English 
We can do a party in my house this weekend

Si quieres hacer preguntas solo tienes que poner primero el Can o el May, luego el sujeto y el resto de la oracion queda igual! =D ... Saludos
