Perfect Squares

A perfect square is a number that can be written as the square of some other number.  But, what does that mean??  It's simple.

9 is a square number because it can be written as 3x3, or 3.  25 is also a square number because it can be written as 5x5, or 5.  When building with tiles, square numbers always have the same length and width, which means they form a square. Can you list the first perfect squares from 1 to 10?
