I believe it is 50, one for each state.

50 No particular star is assigned to a particular state.

how many stars are heir in our flag

Since July 4, 1960–Present: 50. Source and further information: http://en.wikipedia.org/wiki/American_flag

50 S on the A F = 50 Stars on the American Flag. :-)

Currently, there are 50 stars, but the U.S. Army Institute of Heraldry has already established patterns for up to 56 stars, in anticipation of future states.

50

50 stars 13 strips

Fifty at the moment. Didn't used to be though.

50 stars, one representing each state. =]

...on my american flag(the one hanging in my room) there are no stars...on the oe in hte class room there are 50 and my teacher thinks that there are about 48 states.

That would depend on which flag. The Flag Resolution of 1777, That flag of the United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new Constellation. In 1795, the number of stars and stripes was increased from 13 to 15 (to reflect the entry of Vermont and Kentucky as states of the union). April 4, 1818, a plan was passed by Congress at the suggestion of U.S. Naval Captain Samuel C. Reid[24] in which the flag was changed to have 20 stars, with a new star to be added when each new state was admitted, but the number of stripes would remain at thirteen to honor the original colonies. The most recent change, from 49 stars to 50, occurred in 1960 when the present design was chosen, after Hawaii gained statehood in August 1959. Before that, the admission of Alaska in January 1959 prompted the debut of a short-lived 49-star flag. As of July 4, 2007, the 50-star flag has become the longest rendition in use. The 50 stars on the flag represent the 50 U.S. states and the 13 stripes represent the original Thirteen Colonies that rebelled against the British crown and became the first states in the Union.

Presently, there are 50, and I really hope the guy who asked this already knew or isn't American because it would just be sad.

at least 22
