every student in a second grade class sends a valentine to each of the other students in the class, for a total of 306 valentines.How many students are in the class.

The square root of 306 is about 17.5.

So I multiplied 17 * 17 and got 289 Valentines.

There must be 18 students in the class -- and the each sent 17 cards.
