 # Square Array
 
 ## Objectives
+1. Practice iterating over an array using the `.each` method.
+2. Practice operating on each element of an array.
+
+## Instructions
+
+You will build a method, `square_array`, that squares each element of an array of numbers and returns a new array of these squared elements. Please use an iterator and implement your own logic.  Don't use any built in array methods other than `.each`––(collect, inject, etc.)
+
+A few question you can ask yourself: 
+
+* What is the return value of calling `.each` on an array?
+* How can I operate on each element of an array and also collect or store those elements? 
+
+## Bonus
+
+Once you have the tests passing, see if you can implement this with a higher level iterator, maybe `collect`.
+
 
-Make a method that will square all the elements in an array.
